About

PromptMason is a desktop application for organizing reusable prompts and building them from shared text blocks. Users can create blocks for roles, background, tasks and formats, then update a block once to revise every dynamic prompt that uses it. The app includes prompt search, fill-in variables, AI-assisted rewriting, prompt evaluation, and privacy checks that flag sensitive information. Its optional local AI model can run on the user’s computer without sending prompt text to a cloud AI provider. Built-in MCP connections let Claude Desktop, Cursor and Claude Code search, fill and save prompt-library content. Users can also access prompts through a Chrome extension, share libraries using their own cloud-storage folders or a network drive, and manage Markdown documents and downloadable AI Skills. A free plan includes all features with limits of 25 blocks and 15 prompts; Pro removes those limits.
