A workspace for conversation, code, and everything in between.
Polygon is Invariant's conversational AI — rebuilt as a full workspace. Chats, projects, artifacts, code, and design surfaces sit side-by-side, with a sidebar that actually organises what you're working on. Formerly Pluto.
- A real sidebar — switch between Chats, Projects, Artifacts, Code, and Design without losing context.
- Projects that remember your instructions, files, and preferences across every conversation.
- Artifacts you can name, edit, share, and version — not just one-shot responses.
- A built-in code surface that reads, writes, runs, and iterates across files.
- Light and dark themes built top-down so toggling doesn't reshuffle the UI.
How access works
- Open Polygon as a guest — no account needed, hard daily caps apply.
- Sign in to lift caps, save chats and projects, and unlock Apex models and extended thinking.
- Beta features unlock after approval in Settings → Beta.
- Code Studio opens from the Code view in the sidebar.
Free, forever — guest sessions get the same model quality with a tighter daily envelope.

Conversational AI Workspace
Formerly Pluto
What Polygon delivers.
- One workspace for chats, projects, artifacts, code, and design.
- Projects carry your context — instructions, files, style — across every session.
- Artifacts you can edit and share live alongside the chats that created them.
- Code surface with run-and-iterate on real files, not just transcripts.
