FIND YOUR WORK. CHOOSE WHAT GOES NEXT.

The transfer flow
we are preparing.

The Mac app finds your local sessions automatically. Sending starts with a selection; receiving starts with one Key. The transfer service is not connected in this preview.

  1. 01

    Find and select your sessions

    Open the Mac app to see sessions from standard Codex and Claude locations. Search, browse pages, and select one, several, or all conversations in the shown scope.

  2. 02

    Review what you want to send

    Start Send from your selected sessions. This preview shows the review step; it does not upload, charge you, or generate a receive Key.

    Sending by Key is not connected yet
  3. 03

    Receive with one Key

    On the receiving computer, the flow starts with a single receive Key. Its screen can be previewed now; downloading and restoring through it will need the connected service.

PRIVATE BY DESIGN

Some things should
stay in your hands.

The Mac preview reads local conversations for your library. It does not send them to a server. The planned Key-based service will encrypt content before transfer.

  • No model account required here.Sign in to Codex or Claude in their own apps. Session Transfer does not copy agent sign-in or credential files.
  • Your project stays your project.This product is for moving conversations and their required session material. Repository files remain a separate part of preparing the receiving computer.
  • Nothing sent by this website.This website does not scan your computer, accept session uploads or provide a sign-in form.

CLEAR EXPECTATIONS

Know what makes the trip.

Reading a conversation, importing a file, and continuing in the original desktop app are different milestones.

A FEW GOOD QUESTIONS

Before you move.

Does this move my project files too?

No. Bring the repository and any uncommitted changes to the receiving computer yourself. Session Transfer moves the conversation and its required session material. The conversation itself may contain code snippets.

Can I move from Codex to Claude?

The CLI can prepare readable context for another agent. You then review that material and provide it in a new conversation. It does not preserve running processes or private agent state. Key-based handoff is not connected in the Mac preview.

Will opening the app change my sessions?

No. The Mac app reads the standard local session locations to build its library. Browsing, searching and selecting do not change agent files or configuration. The preview does not upload sessions.

Is native desktop recovery ready?

Not yet certified. We are verifying that both agents can show the complete history, continue a new turn, and keep the restored session after restarting on a second computer. A successful file import alone is not this guarantee.

Can I send a session with a Key today?

Not yet. You can review the Send and Receive screens, but the transfer service is not connected. This preview does not create a working Key or take payment. The planned price remains $9.90 per batch.
