The parts the pricing page doesn’t lead with
- Monthly billing costs about 20% more per seat than annual.
- The personal AI agent is gated to Business+ — Pro only gets basic AI.
- On the free plan, everything older than 90 days is held hostage until you upgrade.
The other bill
One plan covers the whole workspace
Openbook replaces Slack inside a full agent-first workspace — boards, docs, chat and 18 room types, with AI agents that write stories, build changes and open pull requests. Start free, then upgrade one shared plan when you need more work. There are no extra seat charges.
