“I want to speak Japanese with my grandson.”

Sathi Beta

Intelligence that grows around your life.

Talk or type to Sathi in your own language. It reads the school mail and the letter on the table, remembers what you have told it, and leaves the decisions to you.⁠*

Start with something you care about

A fictional family, drawn in code. Each step below uses something Sathi does today.

  1. Monday

    It starts from something they already do together.

    I want to speak Japanese with my grandson.

    Sathi:

    What do you two like doing together? We can start there.

    We cook together. Teach me things I can use.

  2. A short lesson, and a recording to practise with.

    Sathi:

    Three things to say while you cook:

    • Kō yatte? Like this?
    • Mō sukoshi A little more
    • Oishii ne! Tastes good!

    I’ve recorded each one twice, so you can listen while you cook.

    They set the pace, and the next step gets smaller.

    That was too fast.

    Sathi:

    Then just one for now. Here it is three times, with a pause after each. Try it as you fold the next one.

    • Kō yatte? Like this?

  3. Thursday

    Days later, the same conversation picks up where it left off.

    Can we practise again? We’re making dumplings together on Sunday.

    Sathi:

    Yes. Last time we slowed down to one phrase. We’ll start there, then add the next.

    • Kō yatte? Like this?
    • Mō sukoshi A little more

  4. Sunday · a family video call

    On the call, it’s the two of them.

    “Kō yatte?”Like this?

  5. After the call

    They choose what comes next.

    Next time, help me ask about his school.

    Sathi:

    We’ll start there next time.

The same Sathi, the rest of the week

The stage

Beta: one deployment, its first families in daily use, and no billing today. Future hosted plans will publish finite allowances before anyone pays.

Sathi’s Hindi and Bengali have not yet been reviewed by native speakers.⁠*

What leaves, and to whomSathi keeps your archive on a server we operate. To help with a task, relevant messages, document or image content, audio and reply text may reach configured model and speech providers. Storage custody is different from processing. The provider entry below describes this boundary; running suitable models ourselves is planned.Storage, models and serving providers →

With us · Working todaySathi Systems operates your private deployment. Your archive is not stored by the model provider. Models may change. Your archive and understanding stay with your Sathi.

What would you like to begin?

Your Sathi starts here.

An account is what lets Sathi remember: your conversations, documents and family circle, kept for you and carried across your devices. You can export it or delete it.⁠*

Get started

Guests can chat freely — no account needed. Sathi keeps no memory of guests; guest conversations are kept for testing and feedback for as long as an operator setting allows (30 days by default).
