Letterly

Letterly is an AI-powered writing education platform that pairs students ages 8-18 with human coaches to build literacy through daily writing, structured feedback, and real publishing. Founded by former Wall Street analyst Jane Chen, the company runs multi-week bootcamps where students draft, revise, and publish articles - and even ship a physical copy of a book they author. Letterly reports serving more than 3,000 students across 30 states and seven countries, with students improving roughly half a grade level in eight weeks.
