How it works
From Slack thread to shipped prompt, in one place.
Set up in five minutes. Use it the same week. No new tools to wedge into the team's workflow.
Connect GitHub
Point mowa at your repos. We scan and import every prompt automatically. No tagging, no config, under 60 seconds.
Invite your team
Owners, editors, viewers, and PM roles. Non-technical teammates can read, suggest, and review without a GitHub seat.
Propose, test, ship
Edits become versioned proposals. Run evals against prior versions. Promote when the numbers move the right way.
Audit, always on
Every change carries an author, timestamp, and reason. The audit log is queryable, exportable, and tamper-evident.
MCP server
Edit prompts from wherever you work.
Every workspace ships with an MCP server. Connect it to Cursor, Claude Desktop, or any MCP-compatible client. Your AI agent can read prompts, list versions, and propose changes that flow through the same review process as your team.
