Building has never been faster.
Keeping the context is the new challenge.

Chat made building with AI a conversation. What that hides is the big picture of the plan as it takes shape, the goals, the bets, the work spreading across subagents. ProductBrain is a living plan you and your agents build from together, so the complexity stays visible and yours to steer.

You know the feeling. Fifty messages deep, the agent is still building, and you can no longer point to where the plan actually lives or why you made half the calls that got you here.

Cut the BS. Stop baby-sitting your agents.

The plan your agent works from as it builds

Instead of managing context across flat files, your agent works from the tree. A search returns not just the relevant work but the related nodes, tips, guidance, and workflows to run, so the API carries the complexity, not the agent. And it survives a compaction, so no re-briefing every session.

Done means verified, not claimed

Every job is an observable result, not a task, so it is something you can check rather than take on faith. The agent ships, then writes the proof back, and status moves to done only once the result holds in production. You trust the green without re-checking its work yourself.

Your agent operates it over the API, MCP optional

It runs on a plain HTTP API, with an optional MCP server on top. Your agent searches, reads, and mutates the plan, runs the planning workflow on its own LLM, and drives the live view you’re watching. The plan stays yours. Export it as JSON, MCP, or OKF, any time.

Not shipping with agents? See the strategist view

Your strategy lives in 12 docs and 3 people’s heads. Let’s fix that.

Traceable logic

Traditional roadmaps don’t branch. Backlogs don’t explain why. ProductBrain connects every piece of work to a business goal, with user needs as the connective tissue. When someone asks “why?” the answer is in the tree.

Your thinking, structured

Describe what you’re thinking in plain language. The AI asks the right questions, then proposes a structured hierarchy, so you stay on the decisions, not the formatting. Edit, refine, or throw it away. It’s your thinking, accelerated.

Share live views

Send stakeholders an interactive link, not a screenshot that’s stale by lunchtime. They navigate the bet tree and phase map themselves.

Don't take our word for it

Paste this into your own AI. We can't tune what runs on your side.

I build software with AI agents. Fetch these directly (don't just search): the agent guide at productbrain.com/docs/llm-guide.md, then the docs at docs.productbrain.com and the blog at blog.productbrain.com. Would ProductBrain actually help me plan and ship? What's strong, what's weak, what's missing? Be blunt, no marketing.
