About
I ran a design agency in Seoul for five years. The projects that fell apart almost never fell apart in the code. They fell apart because nobody had written down what we were actually building. So I started Manyfast. Give it an idea and it drafts the PRD, the feature spec, the user flows and the wireframes, then hands the whole thing to Claude Code or Codex over MCP. About 20,000 PMs use it today, most of them in Korea. Now I'm taking it everywhere else. Always up for trading notes with anyone working on specs, planning, or the handoff to coding agents.
