    How it learns

    It watches.
    It notices.
    It offers.

    1. 01 — Observe

      Watches, on your device

      Which apps you open, when you open them, what you do next. It's stored locally and you can pause it whenever you want.

    2. 02 — Learn

      Finds your patterns

      Standup at 10:00 every weekday. The same three tabs after lunch. Figma straight after Slack. RTIN spots the routine.

    3. 03 — Suggest

      Offers the next step

      A small suggestion floats in. Press Tab and it happens. Ignore it and it fades away. You're always in control.

    Help with anything on screen

    Select it.
    Circle it.
    Ask it.

    Press Tab twice and RTIN helps with what’s in front of you, in any app. On a Mac with Apple Intelligence, it all happens on your Mac.

    1. 01 — Select

      Fix, translate, explain

      Select any text and press Tab twice. Messages get polished, other languages translated, code and jargon explained. Nothing changes until you press Replace.

    2. 02 — Circle

      Circle anything

      Nothing selected? Press Tab twice and draw around a chart, an error, a photo or a screenshot of code. RTIN tells you what it is and points right at it.

    3. 03 — Ask

      Tell it what to do

      End a message with a line like “rtin make it formal” or “rtin translate to Spanish”, then press Tab twice. RTIN does it and removes that line.

    The capsule

    Tab twice.
    It comes alive.

    RTIN lives in a small glass capsule at the edge of your screen. Pink and orange liquid moves as it thinks. Double-tap Tab from any app and it wakes up: select text to polish, translate or explain it, or circle anything on screen and it tells you what it is. You can even type “rtin make it formal” and press Tab twice.

    zzz…

    macOS 26+
