Why Kumiau exists
“I could build ideas quickly with agents and generative tools. What I didn’t have was an easy place to share the thing itself—and a framework for capturing the feedback that would make it better.”
Kumiau is that missing place: the shared space between making an artifact, learning from the right people, and shaping the next version.
One continuous cycle
From artifact to better version—without losing the thread.
Bring what you made, invite the right people, learn in context, and send the learning back to your agent.
Invite the right people
Give teammates, customers, and prospects one shared place to experience and react.

Capture feedback in context
Let reviewers point to the exact screen, state, or component—and keep the conversation attached.

Send learning back to your agent
Your agent pulls the threads, applies the changes, and publishes the next revision.

ANY AGENT · connected over MCPYour agent closes the loop: fetch feedback → iterate → redeploy.
Use cases inside the loop
Use Kumiau wherever an idea needs another set of eyes.
The artifact stays central while different people help shape what comes next.
Product and design reviews
Share a working concept with builders, designers, and PMs before the direction hardens.
Customer and prospect validation
Let external reviewers experience the artifact and react to the exact moments that matter.
Agent-assisted iteration
Send the feedback threads back to your agent and publish a stronger revision.
Built for agents
Your agent doesn’t just watch—it ships.
Over MCP, it pulls the artifact and its comments, applies the feedback, and redeploys the next version—no handoff.
