PromptMason
A private prompt library for people who use AI every day.
The problem
Good prompts get rewritten from scratch, scattered across documents, and pasted into public AI tools along with information that should have stayed private.
What it does
- Build prompts from reusable blocks; improve a block once and every prompt that uses it follows
- Built-in MCP connects the library to Claude, Cursor and other AI apps
- A free AI model that runs on the user’s own computer, so private work never leaves it
- Encrypted team libraries that sync through the cloud drives teams already use, with no PromptMason server
- Desktop app for Windows and Mac, with a companion Chrome extension
