# Pezmu

> Conversation practice with an AI tutor that remembers your life, in Spanish, French, German, Italian, Portuguese, Russian and Greek.
> One long chat about your real day instead of lessons and exercises — and a
> record of every word you've actually produced.

Pezmu is a web app (mobile-first, typed chat) for people who understand a fair
amount of the language they're learning but can't say much, and for people who
learned one once and can feel it slipping. It is not a beginner course and not a
flashcard app.

Seven languages: Spanish, French, German, Italian, Portuguese, Russian and Greek. Each keeps its own words, its own conversation and its
own record; switching between them mixes nothing and deletes nothing, and what
the tutor knows about your life carries across all of them.

It runs in any modern browser on any device — phone, tablet or computer, iOS,
Android, Mac or Windows. There is nothing to install; on a phone it can be added
to the home screen and opens standalone. The account holds the conversation, so
it is the same on every device.

## What makes it different

- **It measures production, not recognition.** Every sentence you write is read:
  which words you used unprompted, which structures you avoid, which mistakes
  repeat, how long your turns run. A word only counts as learned once you
  produce it yourself, with nothing showing it to you.
- **The tutor is calibrated against that record.** It aims each turn one notch
  past what you can already say — a slightly richer word dropped in context.
  Two learners at the same nominal level get different tutors, because their
  output differs.
- **It remembers you.** Your job, the people in your life, what's coming up.
  The conversation continues across sessions rather than restarting. Every
  remembered fact is visible on one page and can be deleted individually.
- **No curriculum, no streaks, no units.** There is nothing to fall behind on.
  The structure is underneath the conversation — in the record — rather than on
  top of it as a syllabus.
- **Feedback is specific and periodic.** Corrections arrive in the moment,
  attached to the sentence you got wrong; longer feedback on your vocabulary
  reach, recurring mistakes and fluency trend arrives every so often, drawn
  entirely from what you wrote.

## Honest limits

- You type; it is not a speaking app. The tutor can read its replies aloud, and
  nothing listens to you speak or grades your accent. Talking back instead of
  typing is not ready yet; we are working on it.
- The tutor is an AI and can be confidently wrong about grammar, a translation,
  or a fact about the world. It is a conversation partner, not an authority.
- In a closed beta, and free while it is. The way in is the waiting list at
  https://pezmu.app/ — places open a few people at a time, and the app admits
  only accounts that were invited. No card at any point. There will be a price
  later; the amount is not decided, and nobody is charged without being told
  first.
- Being in beta means screens and wording change week to week, and some paths
  are newly built. It does not mean the record is disposable: what a learner
  writes is kept and counted the same as it will be later, and they can export
  or delete all of it at any time.

## Privacy, in short

Messages go to Google's Gemini models to generate the tutor's reply and the
word/error analysis, on the paid API tier, where what is sent is not used to
train Google's models. Everything else is stored in Pezmu's own database and
read back to the learner. Nothing is sold or shared with advertisers. Every
learner is shown what is collected and where it goes before their first message.
A learner can download their entire record, delete any remembered fact, wipe
everything permanently, or delete their account outright — all from inside the
app, with no request to anyone. Deleting the account removes the email address
too. Learners must be 16 or over and confirm so before their first message.

Pezmu is run by Sasha Stekhov, an individual based in Cyprus, who is the data
controller. Processors: Google, Supabase, Vercel, Resend.

- [Should you learn words or whole sentences?](https://pezmu.app/blog/learn-words-or-sentences) — Learn the word with its meaning first. Then add sentences to it. Vary them once the word isn't new. The order is what makes a word stick.
- [The intermediate plateau in language learning is real](https://pezmu.app/blog/is-the-intermediate-plateau-real) — Yes, it's real — and half of it is a measurement problem. What stops moving at intermediate, what keeps moving, and why nobody can tell you how long it lasts.
- [Why you understand a language but can't speak it](https://pezmu.app/blog/understand-but-cant-speak) — Understanding and speaking are different skills, and practice transfers to the one you practised. What's really going on, and what to do about it.
