FreeLingo review
An open-source AI tutor with structured practice, available on the web or self-hosted.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FreeLingo is a language-learning app for individual learners who want an AI tutor and a structured practice routine. It combines a CEFR assessment and placement test with a personalized study plan, grammar and vocabulary references, and reading and listening exercises. AI chat and real-time voice conversations add interactive practice, while flashcards, spaced repetition, skill scores, streaks, and end-of-level assessments support ongoing review. It is available as a hosted web app and as open-source software for self-hosting.
The learning flow spans placement, practice, and progress review rather than focusing on conversation alone. AI-generated listening and reading exercises extend practice beyond tutor chat, and flashcards use SM-2 spaced repetition. Progress tracking includes XP, streaks, and skill scores. OpenAI and Ollama integrations give technically inclined learners options for connecting AI services; self-hosting is a meaningful fit for people who want to manage their own deployment. Buyers who want a ready-made mobile app or offline lessons should look elsewhere.
Free Forever includes a 7-day full-access trial, then daily and weekly usage limits. Monthly costs €9.95 per month for unlimited access and renews monthly; Yearly costs €99.5 per year for unlimited access and renews yearly. That makes the free option useful for trying the learning flow, while regular unlimited use requires a paid plan. FreeLingo suits learners comfortable with web access or self-hosting who value AI practice and structured review. It is less suitable for learners who need offline study or a mobile app as their primary learning environment.
