🤝 Handshake
Switch models without losing a word.

Your conversations should not belong to the model you started them in. Import your Claude Code, Claude.ai or ChatGPT history, continue on any model, and switch again mid-thought — the whole history, the attached files and a visible trail of every hand-off move with you. For companies, the same engine measures a migration of your real workload before you commit to it.

Import a Claude Code session and continue it on another model
Real recording: a Claude Code session imported into the Manager, continued on GPT, then handed to a second model — the history travels.

What moves with you

📥

The history

Claude Code sessions found on your machine in one click; Claude.ai and ChatGPT exports; any transcript. It becomes a live session on the model you choose.

📎

The context

Attached files and folders travel with the conversation. The new model sees what the old one saw.

🧭

The trail

Every hand-off is recorded on the session: which turn, from which model, to which. You always know who said what.

Two ways to use it

For you — in the Manager, free

  • Import from Claude Code, Claude.ai, ChatGPT
  • Switch the model in a dropdown; the session continues
  • Fork to a second model and compare side by side
  • Relay: a cheap model drafts, a strong one polishes
  • Cross-check the answers with a neutral jury
  • Export the transcript as Markdown — portability both ways
