Plainify is for developers, designers, product managers, and founders who want AI coding assistants to build from a clearer plan than a short prompt. It turns a product idea into a structured PLAIN specification, helping communicate both what an app should do and how it should look and feel. Start with a brief idea in Relax Mode, or use Custom Mode to work through the spec section by section with guided options and examples. The resulting Markdown file can be used as project context for tools such as Claude Code, Cursor, v0, and Bolt. Plainify is useful when you want to spell out requirements, design direction, and technical choices before asking an AI assistant to generate an app.
