Claude Code and Codex Assist

Claude Code and Codex Assist is a VS Code extension for developers who code with AI agents. It reads the session files Claude Code, Codex, OpenCode, Grok and Copilot keep on your machine and gives you one history for all of them, grouped by project. Open any file to see every prompt that edited it and its diff, undo or reapply any agent edit, search every session with regex, and watch live 5-hour and weekly quota with a projection of when you'll run out. Session Archive keeps transcripts after Claude Code's 30-day cleanup. Works in VS Code, Cursor, Windsurf, Antigravity and Trae, with no account or setup. Free for 7 days of history; Pro from $4.99/month or $49.99 lifetime.
