Highlights
A free tier with no expiry
You can now use ProductBrain free, with no trial countdown. The free tier includes standing API and MCP access, so your own agent can read and write the plan and run the planning workflow with your own LLM, no AI credits spent. It’s the full machine-facing surface, not a teaser. A free project holds up to 50 nodes. It’s a soft cap, checked when you add a node, so you can always delete to make room. It’s there to keep the free tier sustainable, not to start a clock. Outgrow it and the paid tiers lift the cap. Nothing to lose by trying it: shape a real plan, hand it to your agent, and see whether it earns a place in how you build. Start in the Builder quickstart.The live canvas comes with the API, free included
Realtime rides with the machine-facing surface: on Builder plans, including the free tier, you drive the canvas from the CLI or your own agent and watch it update live. That loop doesn’t start behind a paywall. (Strategist is the solo in-app experience. AI credits in place of the API and live canvas.)Export your plan as OKF
Alongside JSON, you can now export a project as an Open Knowledge Format bundle. Portable, typed Markdown that any agent can read. Your strategy is yours: take it anywhere, any time.Other improvements
- Lapsed plans fall back to free, not locked out. If a paid plan lapses, your account drops to the free tier’s rules, never read-only, never a lockout. You keep working under the free cap, with a reminder to renew.
