Read your way
to fluency.

LitBook is an AI language-learning app that generates short reading passages at exactly your level. Every lesson is an original passage on a topic you chose, followed by eight questions — grammar, vocabulary and reading comprehension — with hints in your own language and instant feedback.

Yes. The free plan includes 30 credits every month — enough for a short reading lesson a day. Paid plans with more credits and read-aloud audio are on the way.

French, Spanish, English, German, Italian and Swedish — each at any CEFR level from A0 (absolute beginner) to C2.

None. LitBook starts at A0 with tiny present-tense sentences built from the few hundred most common words, and you can change your level anytime as you improve.

Duolingo is built around gamified micro-drills; LitBook is reading-first — the whole lesson is a passage written at your level, with comprehension checked and your missed words recycled into future passages.

Yes — any lesson can include read-aloud audio of the passage, so you can pair reading with listening. Audio costs extra credits, shown before you generate.

Passages are generated at a controlled level and difficulty, but AI content can contain mistakes. Lessons are for practice, not authority — and questions below B1 never require grammar terminology.

Research consistently shows that large amounts of reading at a level you ~98% understand is one of the most effective ways to acquire vocabulary and grammar naturally. LitBook exists to keep you at that exact level.
