Time-travel any message

Click a line in any session and see the exact code at that instant, rebuilt from your commit history.

Four tools, one timeline

Claude Code, Codex, Cursor & OpenCode — normalized into a single history.

100% local, no server of its own

Your session data never leaves your machine: no LLM calls, no telemetry, no account. The one outbound call reads your own Claude plan windows with Claude Code’s own token, on by default and off in Settings. Source logs and repos are opened read-only and never written to.

Insights across every session

Spend, tokens, and agent-active time — sliceable by model, tool, or first-class Subagents — plus a one-click Security Check for leaked secrets.
