Common questions
What MCP clients are supported?
Thoughtbox is optimized for Claude Code. It also works with Cursor, Windsurf, and any MCP-compatible client.
I have a beta invite code. How do I use it?
Click Get Access, then enter your code in Stripe's Add promotion code field during checkout. If your code is a full comp, your card won't be charged until the beta period ends.
Do I need Thoughtbox for every task?
No. For quick tasks (<10 minutes), your agent thinks just fine natively. Thoughtbox shines for deep research, strategic planning, complex debugging, and architecture design — tasks that take 30+ minutes of sustained reasoning.
