An AI-powered writing coach that keeps humans in the loop - and hands students something schools rarely do: a real audience.
The NameplateA wordmark small enough to fit on a student's byline - which is roughly the point. Letterly puts the kid's name above the fold, and its own below.
Here is a fact that should bother more people than it does: according to the National Assessment of Educational Progress, roughly three out of four American eighth- and twelfth-graders are not proficient writers. That is not a rounding error. That is most of a generation leaving school unable to do the one thing every job, every application, and every argument eventually requires - put a coherent sentence on a page. Jane Chen noticed, and unlike most people who notice, she quit her job about it.
Chen spent about a decade on Wall Street as an investment banker and hedge fund analyst before deciding the world needed her attention elsewhere. She is, by background, a Harvard history concentrator and the New York-born daughter of Chinese immigrants who spent part of her childhood in Shanghai. The pivot to education was not sudden - she had volunteered as a writing tutor for immigrants and taught writing around the country - but the founding was humble. She started the Eyre Writing Center with a poster board that, initially, attracted exactly zero students. Then thirty enrolled for the first term. Then COVID arrived and tripled the enrollment, which is the kind of demand signal that tends to change your business plan. In 2022, the in-person tutoring shop became Letterly, a software platform.
The insight underneath Letterly is unglamorous and probably correct: kids do not write badly because they are incapable. They write badly because they do not write enough, they do not get useful feedback when they do, and they are usually made to write about things they do not care about. Schools optimize for the college essay - a single, high-stakes, formulaic document - and treat everything before it as rehearsal. Letterly's bet is that if you flip all three variables at once, the numbers move. And the company says they do: students improve roughly half a grade level in eight weeks, about twice the pace of school.
Daily reading and writing with personalized human feedback, plus the chance to publish. The Journal is a real online publication built entirely from student work - nearly 15,000 pieces so far.
Students write and publish their own book over six weeks. Letterly prints it and ships a physical copy to the student's door. Not a certificate - a book with their name on it.
Multi-week programs where students ages 8-18 draft anywhere from 10 to 40 articles on topics they choose, each paired one-on-one with an individual coach.
Students submit drafts, receive AI-assisted feedback that a human coach reviews, then revise. The AI drafts the response; a real writer decides what is actually true.
An annual contest judged by a panel that includes Ivy League interviewers, with cash prizes and front-page features. A real stage tends to make kids take the work seriously.
A tool for schools that tracks student writing progress over time, supported by Robin Hood Foundation funding and an early partnership with Brooklyn Tech.
Most edtech pitches promise to replace the teacher. Letterly's pitch is the opposite: use AI to give a human coach superpowers, so every kid gets real feedback on every draft without a company needing to hire an impossible number of English teachers. The coaches themselves are the differentiator - Letterly says they are lifelong learners and award-winning writers, the majority holding degrees from Ivy League or top liberal arts universities in English, education, or related fields.
It is a deliberately labor-heavy model dressed in software. A core team of around seven runs a bench of 50-plus contracted editors and coaches. The AI handles volume; the humans handle judgment. That division is the whole company, and it is why a kid writing about, say, competitive Pokemon gets feedback that treats the subject seriously.
