Set up your second device

Bring your history to another PC.

On PC 1 (the one that already has the history):

  1. Install ChatRelay and choose a backend.
  2. Upload: click Upload now in the Simple view (or Upload everything at the end of setup), or Push on a project in the Advanced view. A preview shows each conversation and any secrets found; you can choose to hide (redact) them in the uploaded copy.

On PC 2:

  1. Install ChatRelay and choose the same backend (the same synced folder, or the same GitHub repo).
  2. Put the project folder on PC 2 (for example with git clone). The path may differ, for example D:\work\shop instead of C:\Users\me\shop.
  3. Click Bring history to this PC (Simple view), or open the Sync view (Advanced view). ChatRelay lists every project in the backend and where it would go on this PC:
    • Git projects are matched automatically by their remote URL.
    • Other projects: click Import into… / Link and pick the local folder once. The link is remembered.
  4. Check the dry run: which files will be written and every path change (for example ×166 C:\Users\me\shop → D:\work\shop). Then confirm.
  5. Open the conversation in the tool: claude --resume or the VS Code Claude panel; codex resume or the Codex sidebar.

For Codex: close Codex first (CLI, VS Code extension and desktop app). ChatRelay never writes to Codex's files while it is running; that conversation is skipped with the reason "Codex is running", and comes in the next time.

Turn on Auto-sync on both PCs and you don't need to do any of this by hand again.
