The smart notebook for people who learn a language for real.
Write down your lesson — Trazo turns it into flashcards, grammar and practice. Everything you learn, organized and remembered, in one place.
Full notebook — free forever · No card · AI free for 14 days
Past tenses: pretérito
Aprendí muchas palabras nuevas hoy. The teacher explained when to use pretérito vs. imperfecto.
New words: el viaje, recordar, de repente.
If you really study a language, your notes end up scattered across paper notebooks and Notion — never reviewed, never connected, never turned into practice. Trazo fixes that.
Four tools that turn lessons into lasting knowledge
Each one feeds the next — capture, remember, practice, reference.
Your lessons, broken down by AI
Type a note or photograph your handwritten page. Trazo's AI reads it and pulls out the grammar rules, vocabulary and example phrases — filed and linked automatically, so nothing is lost between lessons.
- Works with photos of your notebook
- Streaming AI assistant right in the editor
- Every lesson kept by date

Words that come back exactly when you'd forget them
Each word enters a spaced-repetition schedule (FSRS). Trazo decides what to review and when, and the New / Learning / Known board shows your progress at a glance — no manual deck-building.
- Proven FSRS algorithm
- Automatic daily review queue
- Status board built from your real progress

Questions, answered
Who is Trazo for?+
Adults who are actually studying a language — with a tutor, a course, or seriously on their own — and want their lessons to accumulate into real, reviewable knowledge instead of scattered notes.
Which languages does it support?+
Trazo works with several target languages (Spanish, English, French, German, Italian, Portuguese) and native languages. The interface is in English and Russian.
Is it free?+
Yes — the core notebook (lessons, rules, words, examples, practice) is free. The AI features come with a 14-day free trial.
How is this different from Anki or Duolingo?+
Duolingo teaches its own course; Anki only stores cards. Trazo organizes your real learning — your lessons become the rules, cards and games. Think Notion notebook × Anki × an AI tutor.
Do I need to install anything?+
No. Trazo runs in your browser — open the app and start. Your notebook syncs across devices when you sign in.
Your next lesson deserves a notebook that remembers it.
