Combine Sessions
Select sessions from Claude Code, Codex, and Gemini CLI and merge them into a single conversation — giving your next agent the full cross-agent context.
Why You Need This
How this feature boosts your daily productivity
Real projects don't live inside a single AI agent. Claude refactored your API, Codex wrote the tests, and Gemini updated the docs — but each agent only knows what it did. When you start a new session, you lose all that cross-agent context and waste time re-explaining what already happened. Combine Sessions lets you select 2 or more past sessions from any mix of agents, merge their conversation histories, and launch a new terminal pre-loaded with all of it. Your next agent picks up with full knowledge of every decision, every change, and every approach tried — regardless of which agent did the work.
