tbrain
One dashboard for every AI coding session on your Mac — Claude Code, Codex, Cursor, OpenCode and Antigravity, all in one place.
Free · macOS 14 or later · Apple Silicon
What it does
- Watches your existing session files from Claude Code, Codex, Cursor, OpenCode and Antigravity, and lines them up in one list — no separate login or account for any of them.
- Sessions, rules, skills and memory for a project in one screen, updated live as you work rather than only after a session ends.
- Launches agents from the same window. Pick a project and a tool, and it opens a real embedded terminal running that tool — the session keeps running in the background while you look at something else.
- Optional AI summaries. Point it at your own OpenAI or Anthropic API key and it writes a short summary and pulls out memory candidates for each session — off by default, and always your own key, your own bill.
Why it exists
Working across several AI coding tools means the context of what you were doing is scattered across several tools' own session storage, each with its own format and its own place to look. tbrain reads all of it and keeps a single, cross-tool timeline per project, so switching agents doesn't mean losing track of what the last one did.
Using it
Open the app once — it starts its own local hub in the background (a small server and a file watcher, both on your machine only) and remembers it across launches. Pick a project folder, and its sessions, rules, skills and memory show up as soon as it has any.
Click a tool's button at the top to start it against that project in an embedded terminal, right inside the window. Switching tabs doesn't kill the process — it keeps running until you close its tab.
What stays on your machine
tbrain only reads the session folders each tool already keeps on disk — ~/.claude, ~/.codex, ~/.cursor, and the equivalents for OpenCode and Antigravity. Everything it collects goes into one SQLite database under ~/.tbrain on the same machine.
Nothing is sent anywhere unless you turn on the optional AI summarizer and supply your own API key — in that case, the text of a session goes to whichever provider you configured, using your key, and nowhere else. With no key configured, tbrain makes no network calls at all.
What you need
| macOS | 14 (Sonoma) or later, Apple Silicon |
|---|---|
| Useful with | Claude Code, Codex, Cursor, OpenCode, or Antigravity — at least one installed |
The app isn't notarized. macOS will warn about an unidentified developer the first time you open it — right-click the app, choose Open, and confirm once.
tbrain is free and comes with no warranty. It's a tool I built to keep track of my own AI coding sessions and published because it might be useful to someone else running the same mix of tools.
