Claude Code and Codex Assist is a VS Code extension for developers who code with AI agents every day.

Your agents' sessions sit in JSONL files under ~/.claude and ~/.codex. This extension reads them on your machine and turns them into something you can use:

- Every session from Claude Code, Codex, OpenCode, Grok, Copilot and Cursor in one list, grouped by project with the cost of each folder - File Timeline: open any file and see every prompt that edited it, with the diff (git blame for AI conversations) - Undo or reapply any edit an agent made, turn by turn - Search across all prompts, replies and tool output, with exact-phrase and regex matching - Live 5-hour and weekly quota cards that project when you'll run out - Session Archive, so transcripts survive Claude Code's 30-day cleanup

Works in VS Code, Cursor, Windsurf, Antigravity and Trae. No account or setup. Free for the last 7 days of history; Pro is $4.99/month or $49.99 lifetime.

## Features

- **File Timeline**: Open any file and see every session and prompt that edited it, with the exact diff.
- **One history for every agent**: Claude Code, Codex, OpenCode, Grok, Copilot and Cursor sessions in one list, by project.
- **Undo any agent edit**: Per-turn file changes with diff, undo and reapply, plus a Review Changes view.
- **Search every session**: Prompts, replies, tool output and subagents, with exact-phrase and regex matching.
- **Quota burn-down**: Live 5-hour and weekly quota cards that project when you will run out.
