// 01 SEARCH
Find that one conversation in seconds
Search every prompt and reply across thousands of sessions. Results come back grouped by session with the matching message, project, and cost, so you can jump straight to the moment it happened.
- Pick who to search: everyone, only your prompts, or only the assistant
- Match any words, an exact phrase, or a regular expression with one click
- Optionally include tool output and subagent transcripts
// 02 FILE TIMELINE
git blame, but for AI conversations
Open any file and the timeline lists every session that edited it, across Claude Code, Codex, OpenCode, Grok, and Copilot. Expand a session to read the exact prompt and open its diff.
- Auto-follows the active editor, or right-click any file
- Every session and prompt that touched the file, newest first
- Jump from a prompt straight to the diff it produced
// 03 SESSION CHANGES
Review every edit, undo any of them
Every turn shows the files it touched with +/- counts. Open a diff, undo a change, or reapply it. Review Changes gathers every file edit from a conversation in one place.
- Per-turn file cards with +/- line counts
- One-click diff, undo, and reapply for each edit
- Review Changes: every file a conversation touched, in one view
// 04 CONVERSATION VIEW
Every turn, every file it touched
Open a session and read it like a transcript: rendered markdown, code, tasks, and a Turn changes card for each step. Resume it in the terminal, the desktop app, or the Codex extension, or export it as Markdown.
- Per-turn file changes with +/- counts, diff, undo, and reapply
- Context window graph, cache hit rate, cost, and turn count per session
- Resume in Terminal, ChatGPT App, or the Codex VS Code extension
// 05 QUOTA & USAGE
Know when you will run out
Live 5-hour and weekly quota cards for Claude, Codex, Fable, and Grok, with burn-down charts that project when each window exhausts. An activity heatmap and a day-by-day cost table sit right below.
- Exhausts in 2d 4h style projections from your real burn rate
- Contribution-style activity graph with streaks
- Tokens, cost, and session counts per day for the last 7 or 30 days
// 06 MCP SERVER
Let your agents read each other’s history
A local MCP server exposes your session history to Claude Code, Codex, Grok, OpenCode, and Cursor. Say "continue my last Codex session" in Claude Code and it pulls a distilled handoff block.
- search_sessions, get_context, get_session, and list_recent_sessions
- grep_sessions, get_session_changes, and get_file_sessions on Pro
- Loopback only, off by default, one-click setup for every CLI
// 07 SESSION BROWSER

- Pin, rename, hide, or tag sessions to keep large histories tidy
- Live dot on sessions that are still running
