Replit
Browser IDE with AI pair-programming for learners
We publish a full Four-Mismatches fit assessment for the student-facing exam tools first. For this one, the facts below are what we have verified — run the Four Mismatches Test on it yourself for your own students.
Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.
What it does
What the AI actually does — Replit's AI (Ghostwriter, now 'Replit Agent') generates, completes, explains and debugs code inline, and scaffolds whole apps from natural-language prompts.
Why it was built — Let anyone build and ship software from the browser with zero setup — and now, from a prompt.
