The method
How Tooti works
Tooti is built on one idea: learn first what you will hear most. Here is how a learner goes from zero to everyday conversation.
The frequency model
We ranked every word by how often it is really heard in conversation. The curve shows how much everyday speech you understand as you learn words in that order. It rises steeply at first: the first few hundred words do most of the work.
- Words learned
- 316
- Everyday speech understood
- 80%
Measured on 111 million words and tested on conversations the model had never seen.
The memory model
Every word has a memory strength that grows with each successful review. Tooti uses FSRS, an open model trained on millions of real reviews, to predict when your recall will fall to the target and schedules the review just before.
- Reviews in 60 days
- 2
- Average recall over 60 days · With Tooti’s reviews
- 95%
- Average recall over 60 days · Without reviews
- 70%
Each well-timed review makes the memory last longer than the one before, so reviews get rarer over time.
The planning model
Combining both models with your daily time, the planner simulates your learning day by day: new words, reviews and the minutes each one costs. That is how Tooti puts a date on each milestone, and why the date moves when your pace changes.
- Basics · 80%
- ≈ 74 days
- Everyday · 90%
- ≈ 191 days
- Comprehension · 95%
- ≈ 620 days
Estimates from the model, not promises. Your own plan is recalculated every week from your real progress.
1. A placement that respects what you know
In about five minutes Tooti checks three things: which common words you recognise, which basic patterns you can use and how much you follow when you listen.
Words you already know are marked as known and never taught again. Complete beginners skip the test and start with Mission 1.
2. A plan with a date on it
Choose how many minutes a day you can give. Tooti calculates when you can expect to reach each milestone and recalculates every week from your real progress.
If life gets busy, the plan adapts. It never punishes you for a missed day.
3. Missions from real life
Each session is built around a mission: a short scene such as ordering food, meeting someone or asking for help.
You hear the conversation, check that you understood it, learn the new words and patterns inside it, and then use them to answer.
4. Patterns side by side with your language
Grammar is shown as a pattern you can reuse, next to the same idea in your own language. You see what changes and why, without tables to memorise.
5. A memory engine that times your reviews
Every word has a memory strength. Tooti schedules each review just before you would forget, so a few minutes a day are enough to keep everything fresh.
6. A new script without the stress
If the language you are learning uses a different alphabet, a starter module teaches its letters and sounds with words you will meet in your first missions.
Why trust Tooti
Robust by design, honest by default
Learning a language is a big investment of your time. Here is why the plan Tooti gives you is one you can rely on.
Built on real speech
Lessons start from 111 million words of real conversation in 13 languages, not from a textbook’s guess at what matters.
Tested on unseen speech
Each word list was built on one part of the data and checked on conversations it had never seen. It held: 89.8–90.0% coverage, as predicted.
Proven memory science
Reviews are scheduled by FSRS, an open model trained on millions of real reviews and also used by the popular flashcard app Anki.
Plans that correct themselves
Your dates are recalculated every week from your own answers, so the plan stays realistic when life gets busy.
Honest numbers, checked automatically
No “fluent in 30 days”. Every number on this site is stored with its source and checked by automated tests before each release.
Private and dependable
No voice recording, no ad trackers, no chatbot making things up. Every lesson is written and checked, and Tooti keeps working offline.
Your first mission takes five minutes.
