Sololearn
Mobile-first coding lessons with AI practice
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 — 'Kodie', an AI code tutor/chat (2023) that answers questions and generates practice; adaptive lesson sequencing.
Why it was built — Make learning to code feel like a mobile, social, gamified habit for beginners on a phone.
