The Leveller That Multiplies: How AI Tutoring Widens the Education Gap

There is a particular kind of promise that technology likes to make, and it goes like this: the thing that was once scarce and expensive will now be abundant and cheap, and so the people who never had it will finally get it, and the world will tilt a little closer to fair. It is a seductive story. It has been told about the printing press, about radio, about the personal computer, about the internet, and now it is being told, loudly and everywhere, about artificial intelligence in the classroom. A patient, infinitely available tutor for every child on earth. The end of the postcode lottery. The democratisation of quality education, finally, at scale.
It is a beautiful idea. The trouble is that the evidence, as it accumulates through the early months of 2026, keeps pointing in the opposite direction. Not subtly, either. A run of peer-reviewed studies and institutional research published between December 2025 and February 2026 tells a remarkably consistent story, and it is not the story on the marketing deck. The story the research tells is that AI in education, deployed the way it is currently being deployed, is far more likely to widen the gap between advantaged and disadvantaged children than to close it. The leveller, on closer inspection, looks a lot like a multiplier.
This matters enormously, and not only because education is the mechanism through which societies decide who gets to be what. It matters because the gap between the promise and the evidence has become a chasm, and into that chasm governments are pouring public money, vendors are pouring product, and children, millions of them, are being enrolled in an experiment whose results nobody has bothered to wait for. The question is no longer whether AI can help some students learn. It plainly can. The question is who it helps, who it leaves behind, and who is supposed to answer for the difference.
The Study Nobody Wanted to Read at the Product Launch
Begin with the most direct rebuttal to the democratisation narrative, because it is admirably blunt. In February 2026, the journal Frontiers in Computer Science published a paper titled, with no particular diplomacy, “AI and the digital divide in education.” Its authors, Mokgata Alleen Matjie, Andani Nethavhani and Mary Matlakala, set out to examine what actually happens when AI tools enter educational systems that contain, as nearly all educational systems do, both well-resourced and under-resourced learners.
Their conclusion is the sort of sentence that does not appear in a vendor's promotional video. AI, they write, “might bring more harm than benefits with its biased algorithms, cultural, and language insensitiveness.” The benefits, they found, concentrate among privileged learners in wealthy regions, which happen to be precisely the regions where the tools were designed in the first place. This is not an accident of distribution. It is a feature of how the technology was built and for whom.
Consider the mechanics, because they are where the unfairness lives. A large language model is, at root, a machine that has learned patterns from an enormous corpus of text. The corpus is overwhelmingly English, overwhelmingly Western, and overwhelmingly produced by and for people who already had reliable internet access and the leisure to write things down. When a child whose first language is Tshivenda, or Tamil, or any of the thousands of languages thinly represented in that corpus, sits down with such a tool, they are not meeting a neutral tutor. They are meeting a system that performs best for someone unlike them. The Frontiers authors put it plainly: when “AI tools are developed in a language unfamiliar to the learners, they are bound to struggle” relative to those whose languages shaped the design.
Then there is the algorithmic bias, which is quieter and arguably nastier, because it hides inside the appearance of personalised help. The study found that students from lower-income communities are “more likely to receive less accurate or less supportive guidance, reinforcing disadvantage.” Sit with that for a moment. The tool sold as a personal tutor delivers a worse tutorial to the children who can least afford a worse one, and it does so invisibly, wrapped in the same friendly interface that serves a richer child something better. There is no obvious moment of denial, no locked door, no sign reading “not for you.” There is just a steady, frictionless drip of slightly inferior help, accumulating over years.
The researchers also surfaced something subtler than infrastructure, drawing on a case study from rural China. The problem there was not only that rural schools lacked devices and bandwidth. It was that rural teachers lacked professional development in digital pedagogy, a gap the authors describe through the framework of technological pedagogical knowledge, a TPACK divide. In other words, even where you hand the hardware to a rural school, you have not handed it the capacity to teach with it well. The kit arrives. The knowledge of how to wield the kit does not.
When the Evidence Comes From the Wrong Schools
If the Frontiers paper is the prosecution's opening statement, the Brookings Institution's January 2026 work is the forensic accountant quietly noting that the evidence everyone keeps citing was collected in suspiciously favourable conditions.
Brookings published two relevant pieces of work in that month. The first, a research review by Mary Burns on what the evidence actually shows about generative AI in tutoring, is genuinely encouraging in places, and it would be dishonest to pretend otherwise. Burns walks through randomised controlled trials in which AI tutoring systems performed core functions traditionally handled by human tutors and produced real learning gains. One trial saw an AI tutor more than double learning gains over a conventional classroom model. Another found a language-model assistant lifting middle-school mathematics achievement, with the largest benefit accruing to novice human tutors who used it as support. This is not nothing. The promise is not pure vapour.
But Burns is careful, and her care is the point. She acknowledges that “many claims about the educational benefits of generative AI have outpaced high-quality evidence,” and she stresses, repeatedly, that design matters, that the gains depend on pedagogically sound implementation rather than on the mere presence of the tool. Read the studies she cites and a pattern emerges that should give any policymaker pause. The trials that produced the good headlines were largely run in well-funded, technologically equipped settings, in environments built and staffed and connected in ways that bear almost no resemblance to the conditions in which the majority of the world's children are actually educated. The evidence base, in short, is drawn disproportionately from the kind of school that least needs the help.
This is the methodological version of testing a flood barrier exclusively on dry land and pronouncing it excellent. The places where AI tutoring has been shown to work are the places already rich in the things, reliable connectivity, trained staff, functioning devices, ambient digital literacy, that make almost any educational intervention work. To take those results and generalise them to an under-resourced school in the global majority is not science. It is wishful extrapolation dressed in the borrowed authority of a randomised trial.
The second Brookings output that month made the institution's broader judgement unambiguous. “A New Direction for Students in an AI World: Prosper, Prepare, Protect,” authored by Mary Burns, Rebecca Winthrop, Natasha Luther, Emma Venetis and Rida Karim, drew on a yearlong global study spanning more than 500 stakeholders across 50 countries and a review of over 400 academic studies. Its central finding lands like a cold flannel on the foreheads of the more excitable advocates. “At this point in its trajectory,” the report concludes, “the risks of utilizing generative AI in children's education overshadow its benefits.”
The asymmetry the Brookings team identifies is the crux of the whole problem, and it deserves to be spelled out. The risks of AI in education, they argue, tend to undermine foundational child development directly, regardless of how carefully you deploy. The benefits, by contrast, are conditional. They only materialise when the deployment is good, when the pedagogy is sound, when the surrounding system is competent. Poor deployment does not merely fail to deliver benefits. It can actively prevent positive outcomes from materialising at all, and it can inflict harm that lands hardest on the children with the least capacity to absorb it. The report's framework, the three pillars of prosper, prepare and protect, is in essence an argument that you cannot bolt AI onto a fragile system and expect anything other than amplified fragility.
A Village in Rajasthan and the Anatomy of a Barrier
Abstractions about distribution and asymmetry are easy to nod along to and easy to forget. So consider a more granular picture, the one assembled in a study of large language models in K-12 education in rural India, the work of Harshita Goyal, Garima Garg, Prisha Mordia, Veena Ramachandran, Dhruv Kumar and Jagat Sesh Challa at the Birla Institute of Technology and Science, Pilani. The peer-reviewed examination of LLM use among rural Indian students that surfaced in the December 2025 research conversation makes the gap between promise and practice almost tactile.
The researchers conducted semi-structured interviews with 23 student volunteer teachers working in rural schools across Rajasthan and Delhi, young educators with an average age of 22.5 and around three years of teaching behind them, people close enough to the chalkface to know what is actually happening in the room. What they reported is a catalogue of the barriers that the democratisation narrative tends to wave away.
Start with the internet, that quiet precondition for everything else. Fifteen of the 23 volunteers identified inadequate infrastructure as a serious obstacle, describing connectivity as a huge issue. As one put it, most schools simply do not have reliable internet and tech access is limited. An AI tutor is a remarkable thing when it loads. It is a blank screen and a wasted lesson when it does not.
Then teacher training, or rather its absence. Thirteen of the 23 flagged the lack of access to any AI training. One volunteer offered an observation that should be printed and pinned above every ministerial desk currently authorising a national rollout: “I don't think most government school teachers are aware of GenAI yet.” You cannot deploy your way around that sentence. A tool that requires pedagogical skill to use well, handed to a workforce that has had no opportunity to acquire that skill, does not become a tutor. It becomes, at best, a distraction, and at worst a substitute for teaching that the system was already struggling to provide.
Language surfaced again, exactly as the Frontiers authors predicted it would. Participants described English-language design as a real barrier, noting that students struggle with English while the very textbooks, the NCERT materials at the centre of Indian schooling, are themselves in English. A tool optimised for English-speaking users meets a child wrestling with English as a second or third language, and the gap between the tool's confident fluency and the child's actual comprehension becomes one more place to fall. It is worth dwelling on how this compounds. A child who already finds the textbook a linguistic obstacle is now handed a digital tutor that speaks the same foreign language even more fluently and even more confidently, and the apparent authority of the machine can paper over a comprehension gap rather than close it. The tool sounds certain. The child nods along. Nobody, least of all an overstretched teacher with thirty other pupils in front of them, is positioned to notice that the understanding never actually arrived. A poorer child in a wealthier child's classroom would at least share the same baseline of language and infrastructure. Here the deficits stack: weaker connectivity, weaker device access, a language barrier and an untrained teacher, each multiplying the others rather than merely adding to them.
And affordability, the most stubborn barrier of all. Eleven of the 23 cited cost. Many families, they reported, cannot afford consistent data or even a single device per child. The personalised tutor is not personalised if four siblings are sharing one cracked phone on a patchy connection in the hour before the battery dies.
The volunteers were not technophobes. They saw the potential, the capacity for personalisation, the possibility of lightening an overstretched teacher's load. But they were clear, eight of them explicitly so, that AI should be a complementary tool and not a replacement for teaching, and they worried about students becoming over-reliant on it at the expense of learning to think for themselves. The practical benefit they observed, in other words, fell far short of the promotional claims. The brochure described a revolution. The classroom described a series of obstacles, each of which fell hardest on the children who already had the least.
The Pace Problem
You might reasonably expect that a body of evidence this consistent, arriving this quickly, would induce caution in the people responsible for spending public money on AI in schools. You would be disappointed.
The New York Times reported in January 2026 that governments rolling out AI tools across their school systems were doing so faster than the research on educational impact warranted. Some experts quoted in that reporting issued a warning that ought to function as an emergency brake: poorly deployed AI could actively harm learning outcomes, and it would do the most harm to the students least able to absorb it. That is not a caveat. That is a fire alarm.
The pattern the Times identified is corroborated from other quarters. The Center for Democracy and Technology has warned that the momentum to deploy AI in K-12 schools is outpacing the guardrails needed to protect students. Survey work from the RAND Corporation has found AI becoming a default study tool across K-12 education, frequently without school guidance or parental knowledge, even as a growing majority of students themselves believe it harms their critical thinking. When the kids using the tool are more worried about its effects than the officials deploying it, something has gone wrong with the chain of accountability.
The temptation here is enormous, and it is worth naming honestly because it is not stupid. Education systems are chronically short of teachers, chronically short of money, and chronically short of time. A technology that promises a tutor for every child, at marginal cost approaching zero, is exactly the kind of miracle a finance ministry dreams about. The democratisation narrative is not merely marketing. It is also a genuine hope, held sincerely by people trying to solve real and painful problems. That is precisely what makes it dangerous. The most seductive false promises are the ones that answer a real need.
But hope is not a deployment strategy, and the speed of these rollouts has a specific, corrosive logic. The research takes years. The procurement cycle takes months. The political incentive to announce a bold modernising initiative takes about a week. So the announcements race ahead of the evidence, the contracts get signed, the tools get pushed into classrooms, and by the time anyone has rigorously measured the effect on actual learning in actual under-resourced schools, the next initiative is already being announced. The evidence, when it finally arrives, lands in a world that has stopped waiting for it.
Why a Leveller Becomes a Multiplier
It is worth being precise about the mechanism, because “AI widens inequality” can sound like a vague incantation if you do not show the gears turning. The reason a tool can be sold as a leveller and behave as a multiplier is not mysterious. It is structural, and it repeats across every study cited here.
A new educational resource is never absorbed into a vacuum. It is absorbed into an existing system, and that system already has a distribution of advantage. The well-resourced school receives the AI tutor along with the reliable fibre connection, the device for every pupil, the teacher who has been trained to integrate the tool into a coherent lesson, the parents who can troubleshoot at home, and the ambient digital fluency that makes the whole thing feel natural. In that environment, the tool does roughly what the brochure said. It personalises, it supplements, it extends a good teacher's reach. The Brookings trials caught exactly this, and there is no reason to doubt them.
The under-resourced school receives the same tool and almost none of the surrounding infrastructure. The connection drops. The device is shared or absent. The teacher, through no fault of their own, has had no training. The tool, designed in a distant language for a distant context, performs worse for these particular children, and it does so quietly. So the same technology, dropped into two different systems, does not equalise them. It tracks the inequality that was already there and, because the affluent system can extract far more value from it, it widens the distance between the two. This is the TPACK divide from the China case study, the language barrier from rural Rajasthan, and the algorithmic bias from the Frontiers paper, all describing the same underlying physics from different angles.
There is a grim elegance to it. You do not need anyone to act in bad faith. You do not need a conspiracy to disadvantage the poor. You need only to distribute an unequally usable tool across an already unequal landscape and let the existing gradient do the work. The democratisation narrative assumes the tool is the great equaliser. The evidence shows the tool is a faithful amplifier of whatever it is plugged into, and what it is plugged into is not equal. The history of educational technology is, depressingly, a series of variations on this theme. Each new medium arrives wrapped in the language of access and arrives in practice as an accelerant of existing advantage, because the families and schools best placed to exploit it exploit it first and hardest. What is genuinely new about AI is the quietness of the failure. A missing textbook is visible. A broken laptop is visible. A tutor that simply performs a little worse for poorer children, while smiling the same smile and offering the same interface, leaves no mark anyone can point to. The inequality it produces is real but evidence-free at the level of the individual classroom, which is exactly the kind of inequality that is hardest to argue against and easiest to deny.
What Equitable Deployment Would Actually Require
So what would it take to make this technology behave like the leveller it is marketed as, rather than the multiplier the evidence reveals? The studies, read together, sketch an answer, and it is considerably more demanding than buying a licence and issuing a press release.
It would require, first, that the tools be built for the children who most need them rather than retrofitted from tools built for everyone else. The Frontiers authors are explicit on this. They call for multilingual, culturally responsive AI systems and for diverse, representative datasets to mitigate algorithmic bias. This is not a cosmetic localisation, not a translation layer bolted on at the end. It means including the languages and contexts of disadvantaged learners in the design and the training from the beginning, so that the tool performs as well for a child in rural Rajasthan as it does for a child in a wealthy suburb. That is expensive and unglamorous and commercially unattractive, which is precisely why it does not happen by default.
It would require, second, the pedagogical infrastructure without which the tools are inert or harmful. The rural India study and the China case study both hammer the same nail. Hardware is necessary and nowhere near sufficient. Teachers need genuine training, not a one-hour webinar, in how to integrate these tools into sound teaching. The Brookings prepare pillar is built entirely around this idea of capacity-building for educators and students, and it is the pillar most often skipped, because building human capacity is slow and undramatic in a way that announcing a technology partnership is not.
It would require, third, that deployment proceed at the speed of evidence rather than the speed of procurement. This is the direct rebuke to the pattern the New York Times documented. It means running the trials in the conditions that actually prevail in under-resourced schools before scaling, rather than generalising from results obtained in rich ones. It means the willingness to conclude, as Brookings did, that at this moment the risks may overshadow the benefits, and to act on that conclusion rather than to bury it beneath an announcement.
And it would require closing the equity gap deliberately, with money and design and political will, rather than hoping the technology will close it as a happy side effect. The Brookings report calls for innovative financing to close equity gaps and for tools co-created with educators, students, parents and communities. The common thread is intention. Equity does not emerge from the unsupervised diffusion of a clever tool. It has to be engineered, paid for, and protected against the gradient that is always trying to reassert itself.
The Accountability Question Nobody Wants to Own
Which brings us to the hardest part of the question, the part that the technology industry is structurally allergic to and that governments are politically reluctant to grasp. If a tool is sold to the public on a narrative of democratising quality education, and it turns out instead to widen the gap between the advantaged and the disadvantaged, who is accountable?
The honest answer is that, at present, almost nobody is, and that is itself the scandal. Responsibility in this system is diffused to the point of evaporation. The vendor builds a tool and markets its potential, then points out, accurately, that outcomes depend on how schools use it. The government procures the tool and announces the initiative, then points out, accurately, that it relied on the vendor's claims and the apparent weight of the research. The researchers produce the encouraging trials, then point out, accurately and often in the very same papers, that their results came from well-resourced settings and should not be over-generalised. Everyone has a defensible position. Everyone has someone else to point at. And the child in the under-resourced school, who was promised a tutor and received a barrier, has no one to point at at all, because the entire structure has been arranged so that the harm has no author.
This is not acceptable, and the way out of it is not more sophisticated blame-shifting but a clear allocation of duties. Vendors who sell a tool on an equity narrative should be held to that narrative, which means being required to demonstrate that their products do not perform systematically worse for disadvantaged learners, the precise failure the Frontiers study documented. The marketing claim and the measured outcome should be allowed to collide in public. Governments that deploy these tools at public expense are accountable for the conditions of deployment, for the connectivity, the teacher training, the linguistic fit, and for the basic discipline of not scaling faster than the evidence permits. A minister who rolls out a national programme on the back of trials conducted in conditions nothing like their own schools owns the gap between the two, however inconvenient that ownership may be at the next ribbon-cutting. And the research community, to its considerable credit already doing this in the studies discussed here, bears a continuing duty to keep saying loudly that the evidence comes from the wrong schools, and to resist the quiet pressure to let promising results be laundered into universal claims.
The deepest problem is that the democratisation narrative does a specific kind of damage entirely separate from any individual tool. By insisting in advance that AI is a leveller, it pre-emptively absolves everyone of the duty to check whether it is. If the technology is equalising by its very nature, then there is nothing to monitor, no distributional outcome to measure, no accountability to assign. The story does the work that scrutiny ought to do. That is what makes it so much more dangerous than ordinary marketing. It is not merely overselling a product. It is disabling the alarm system that would otherwise tell us the product is making things worse.
Holding Two Truths
None of this is an argument that AI has no place in education, and it would be a betrayal of the evidence to pretend otherwise. The Brookings trials are real. The learning gains in well-designed deployments are real. The rural volunteers in Rajasthan saw real potential, and they were not naive to see it. Used well, with the right languages and the right training and the right humility about pace, these tools can genuinely help children learn. That truth and the harder truth can be held at once, and holding both is the entire discipline the moment demands.
The harder truth is that “used well” is doing enormous and largely unacknowledged work in that sentence. The conditions under which AI helps, reliable infrastructure, trained teachers, culturally and linguistically appropriate design, and a deployment pace governed by evidence, are exactly the conditions that under-resourced schools lack. Without those conditions, the same technology that lifts the advantaged child does little for the disadvantaged one and may quietly set them back, and the net effect across a system is to stretch the distance between them. That is the mechanism every study cited here describes from a slightly different vantage, and it does not stop operating because the marketing insists it should.
The democratisation of education is a goal worth wanting with everything we have. It is precisely because it is so worth wanting that it should not be handed over to a narrative that congratulates itself on the outcome before the outcome has been measured. The evidence from late 2025 and early 2026 is a gift, if anyone in a position of power is willing to receive it as one. It arrived early, while the rollouts are still young and the harms still reversible. It tells us, clearly and in time, that the leveller is behaving like a multiplier, and that whether it goes on doing so is not fixed by the technology but chosen by the people deploying it. The tools will do what we build them to do and put them where we put them. The accountability for that, finally, is ours, and it cannot be coded away.
