AI language learning platform
Learn with Lingu, your AI language tutor.
Follow a personalized study plan, reinforce what you learn with exercises and games, and put it into practice in voice conversations with Lingu.
Features
Everything in one structured learning loop.
AI tutor chat and memory
Lingu remembers useful details across all your learning languages, while you can add, review, or delete memories from Settings.
Voice conversations
Put your lessons into conversation with Lingu. Start voice practice from a completed lesson, ask questions, and revisit the transcript afterwards.
Listening and reading
Generate level-aware audio and reading comprehension exercises that match your current study language.
Review and learning games
Review vocabulary with spaced-repetition flashcards, consult grammar and useful phrases, and reinforce your learning with Error Detective, Sentence Order, and Vocabulary Pairs.
Multi-language progress
Study English, Spanish, Italian, Portuguese, German, French, Japanese, Korean, and Mainland Chinese side by side, with separate plans and progress for each language.
Cloud or self-hosted
Two ways to use FreeLingo.
Choose a managed service to focus on learning, or run your own installation for control over configuration and infrastructure.
Each installation has its own accounts and progress. Cloud links open the official service at freelingo.app; self-hosting links explain how to set up your own installation.
We manage it. You learn.
Learn in your browser without installing or maintaining anything.
- Hosting, maintenance and updates included.
- AI and voice included within your plan's usage limits.
- Start free without a card, with Premium available for more practice.
Your infrastructure. Your configuration.
Install FreeLingo on your server and choose your AI and voice providers.
- Free, open-source software under AGPL-3.0. No FreeLingo Cloud subscription required; your administrator configures access and limits.
- You handle setup, updates and backups, and cover infrastructure and provider costs.
- Requires Docker Compose and configured AI and voice services; hardware and voice-language support depend on your providers.
External AI or voice providers receive the content they process. Self-hosting does not automatically make all processing local.
Installation guideOpen Source
Built in the open, auditable by anyone.
FreeLingo's source code is available under AGPL-3.0. Inspect it, contribute, or run your own installation. Organisations that need a customised or white-labelled deployment without AGPL obligations can explore the commercial licence.
