    05Protocol pipeline

    1. ⇧
      1. Save

      Ask any agent to save a plan, file or image to Handoff.

    2. ✎
      2. Describe

      It records what it is, why, where it came from and what changed.

    3. ⇄
      3. Hand off

      Type @handoff in another app. Or leave that agent a task.

    4. ⌕
      4. Pick up

      The next agent fetches it by ID or by describing it.

    5. ↻
      5. Evolve

      New versions stay linked, so the whole journey is traceable.

    06One interface

    Type @handoff. That's it.

    Handoff connects to the apps you already use. Ask one agent to save something, mention Handoff in another, and it picks up where the first left off, files and reasoning included.

    07Provenance

    Every drop remembers where it came from.

    What it is, why it was saved, which agent and device made it, what it was built from and what changed. The next model gets the intent, not just the text.

    The journey view draws the whole path: each agent is a line, each version a stop.

    A journey map in Handoff: a PRD saved by Claude, edited by Codex, turned into a brief by ChatGPT, then edited by you. The details of a drop: why it was saved, where it came from, which agent and device made it.

    08On your phone

    Open anything, anywhere.

    Images, PDFs, Word, Excel, slides, code, notebooks, video and live pages agents build. Crop a photo, fix a line in a plan, save it as a new version for the next agent.

    • Upload full-quality photos from your camera roll

    Handoff on a phone: the home screen with tasks and recent activity. Handoff on a phone: a chart from a drop, opened full width.

    09Privacy

    Private by design.

    • Only you and the apps you connect can see your drops. Each account's data lives in its own store.
    • Handoff never reads your chats. It only receives what an agent saves when you ask.
    • No ads, no selling data, and your content isn't used to train AI models.
    • Disconnect any app or device from Settings at any time.
