Kenya's 40,000-Writer Essay Mill Is Gone. The Last Job Is Humanizing AI.

TL;DR

The New York Times reported on September 5 that Kenya's academic ghostwriting industry, which researchers estimated employed up to 40,000 people in Nairobi at its early-2020s peak, has all but disappeared in the two years since ChatGPT launched. The story's central figure, Teresios Bundi, wrote more than 2,500 essays for overseas students over 12 years and ran a shop charging $40 to $70 a paper before the orders stopped. Independent reporting shows the slide began within months of ChatGPT's release, and a benchmark from Scale AI and the Center for AI Safety says the share of real freelance projects an AI agent can finish has more than quadrupled since last October. The lesson for anyone building a product is about demand, not price: the customers did not switch to a cheaper vendor. They stopped needing a vendor.

What the Times found

The report, by Adam Satariano and Paul Mozur, follows Bundi from his arrival in Nairobi in 2011 to attend university. His first assignment for a foreign student paid $7 for three hours of work. "That was a lifeline for me. I needed the money. I could not sleep that night," he told the paper. Over the next 12 years he estimates he wrote more than 2,500 essays, sometimes three a day. "It was like getting a parallel education," he said.

He built it into a business: a rented house near the university with desks, internet, and mattresses for the student workers, charging $40 to $70 per paper. After finishing his public health degree in 2015 he stayed in essays, because they paid at least five times what public health did. "I never would have expected AI could do this," he said. He now works for a German government development organization.

The other people in the piece trace the same arc. Richard Esilaba grew his operation to 100 ghostwriters, closed it, and now does photo editing. Alex Munyua, a 30-year-old industrial chemist who found essays paid better than chemistry, moved to data labeling and social media moderation. "Some have gone back to the villages," he said. A writer identified only as Alphline, who started in 2021, now works as a "humanizer": she uses AI for the first draft, then rewrites it so it reads as human. "I can clearly tell a paper that's AI-generated compared to one that's human-generated," she said.

The Times also gives the macro backdrop. Kenya turns out more than 100,000 university graduates a year into an economy where roughly 80 percent of work is informal and about 40 percent of its 54 million people live in poverty. In 2022 the government adopted a ten-year National Digital Masterplan that leaned further into outsourcing and online gig work as the path for those graduates. That is the same year ChatGPT launched. Oxford's Mark Graham, who studies the global gig economy, told the paper that "it's not just going to be Kenya."

Where the 40,000 comes from

The headline number is a researcher estimate, and it predates the collapse. It comes out of the work of Oxford sociologist Patricia Kingori, who published on Kenya's "fake essay" writers in 2021 and then fronted The Shadow Scholars, Eloise King's documentary about the industry. The film premiered at IDFA in November 2024, reached UK cinemas on September 16, 2025, and aired on Channel 4 eight days later. By the time it hit theatres it was closer to a period piece.

KQED's coverage of the film in August 2025 fills in the shape of the trade. Roughly 40,000 writers worked out of Nairobi, a number that swung with the academic calendar and could double at the end of a semester. About 72 percent of Kenya's online labor was writing and translation. The global contract-cheating business was put at about $15 billion, and the writers saw roughly 30 percent of what students paid, with agencies keeping the rest. The agency layer was the real platform, and it folded first.

The slide started in the first months

The Times is writing the ending, but the beginning was documented in real time. In April 2023, five months after ChatGPT's launch, Rest of World interviewed Nairobi writers who were already watching the floor drop. Collins, 27, had made $900 to $1,200 a month in 2022 and was down to $500 to $800, with his monthly assignments falling from 50 to 70 to 30 to 40. Wade Brian, a finance student, had handled up to 60 assignments in a good month in 2022 for $296; in March 2023 he got 10, worth under $74. The same piece cited a January 2023 survey by Study.com of more than 1,000 students in which 89 percent said they had used ChatGPT for homework and 53 percent for an essay.

One quote from that 2023 piece reads differently now. John Kamau, a writer since 2014, was unbothered: "Work will still be there because even editing the AI-generated text to avoid detection takes a lot of time." He was right about the job and wrong about the industry. Editing AI output to beat detectors is, per the Times and TNW's follow-up, most of what remains.

Why it vanished instead of shrinking

Industries usually get squeezed. This one evaporated, and the mechanism applies to more than essays.

The essay mill was already an API. A student pasted an assignment into a marketplace form or a Facebook group, paid per unit, and got text back a day later, without ever learning the writer's name. No brand, no relationship, no switching cost. ChatGPT offered the identical interface with seconds of latency and a marginal cost near zero. Demand did not move to a cheaper competitor. It moved to the model.

Think of it as a vending machine with a person hiding inside. For fifteen years the customer pushed a button and a snack came out, and the person inside was paid by the snack. Once the machine could dispense on its own, nobody missed the person, because nobody had ever seen them. That invisibility is the whole point of Kingori's "shadow scholars" framing, and it is also why the collapse was so quiet.

What survives is the adversarial residue. Universities run detection software, so students pay a human to make the model's output look human. That is a market whose entire reason to exist is another vendor's classifier, which means it has the half-life of a detector update. Universities spent years and real money trying to kill the essay mills. A free research preview did it in about two years, as a side effect.

The benchmark says this was the easy tier

Essay writing never needed a benchmark; it is the thing language models do. The question is how far up the difficulty ladder the same disintermediation reaches, and there is now a gauge. The Remote Labor Index from Scale AI and the Center for AI Safety scores agents on 240 real, paid freelance projects sourced from Upwork across 23 domains, with a combined value of $143,991. Human graders judge whether the deliverable would be accepted by the client who commissioned it. The paper came out at the end of October 2025, and the best agent at launch finished 2.5 percent of the projects.

By the July 1, 2026 update, Fable 5 sat at 15.8 percent, with Opus 4.8 at 8.3 percent and GPT-5.5 at 6.3 percent. In CAIS's words, "the frontier has more than quadrupled in under eight months." The Times rounds that to 16 percent. The projects on the leaderboard are 3D and CAD work, architecture, graphic design, video and animation, audio, data analysis, and web apps, all far harder than essays.

The essay industry died at a point when frontier agents could not complete three percent of a real Upwork project. The work Kenya's displaced writers moved into, and the work the Masterplan explicitly targets, is transcription, data labeling, moderation, and business process outsourcing. That is the tier the index is now measuring, and the number is moving fast.

What a builder should take from this

• Category risk beats competitor risk. The mills did not lose on price or quality to another mill. The category stopped existing. If your product is a text-in, text-out service a customer would rather not have to talk to a human for, the threat is not the startup next door.
• No relationship, no moat. Marketplace-mediated, per-unit, anonymous work has zero switching cost by design. The agencies that took 70 percent of the fee were the platform, and they were the first layer to go.
• Adversarial residue markets are a trap. "Humanizing" exists only because detectors exist. Building a business on the gap between one model and another vendor's classifier is building on a moving part.
• Concentration compounds it. When 72 percent of a country's online labor is one task type, one model release is a macro event. Same for a company whose revenue is one task type.
• Watch the RLI, not the demos. A benchmark that grades agents on whether a paying client would accept the work is the closest thing to an early warning for the next tier.

Caveats

The 40,000 figure is an estimate that predates the collapse, fluctuated with the academic calendar, and the Times does not put a current headcount against it. No essay platform has published order data, so the trajectory rests on reporting, not a dataset. Rest of World's 2023 numbers come from four named writers and are anecdotal. The Remote Labor Index measures a harder class of work than essays and says nothing about essays directly; the link between the two is an argument, not a measurement. Kenyan youth unemployment figures vary by a factor of five depending on definition, so this piece does not cite one. And this was contract cheating: the labor story and the academic integrity story point in opposite directions.

Key Takeaways

• The New York Times reports Kenya's academic ghostwriting industry, estimated at up to 40,000 people in Nairobi at its peak, has all but vanished within two years of ChatGPT's launch.
• Teresios Bundi went from a $7 first essay in 2011 to a shop charging $40 to $70 a paper and 2,500-plus essays over 12 years; a 100-writer operation in the same story has closed.
• Rest of World documented the drop in April 2023: one writer's income fell from $900-1,200 a month to $500-800, another's from $296 to under $74.
• The remaining work is "humanizing" AI drafts to beat detection software, a market that exists only because detectors do.
• Scale AI and CAIS's Remote Labor Index rose from 2.5 percent at launch in October 2025 to 15.8 percent by July 2026, putting the next tier of outsourced work in range.
