Every agent at once, not one in an editor.
Claude Code, Codex, Grok and the Terramind agent, side by side on subscriptions you already pay for.
Bring your Claude, ChatGPT or Grok subscription. Open your repo and go.
The rest of the launch, in the same app.
The deck, the spreadsheet, the release video and the forecast come out of the same chats.
Side by side, row by row.

Agents that know what the team decided.
Issues, docs, decisions and goals from Spaces are in every chat, and a plan becomes an issue.
Keep your editor open beside it.
Nucleus works on your local repo, so any editor can stay open on the same folder.
- Same folder
- Worktree per chat
- Review in place
Before you decide.
When is Cursor the better choice?
If you want an editor first, with completions as you type, Cursor is built around that.
Do I have to give up my editor?
No. Your editor can stay open on the same folder while agents work in Nucleus.
Does my code leave my machine?
Your repo and worktrees stay on your Mac. Cloud runs upload the work only when you start one.
What does it cost?
Free to start, and one subscription covers both apps. Agents on your own subscriptions bill to those, not to your credits.
Is it Mac only?
Yes, for now. Nucleus and Spaces are built for Apple silicon Macs, and there are no Windows or Linux builds yet.
Every agent at once, on all the work.
Works with the Claude Code, Codex and Grok subscriptions you already have.
