The insight

The best prompts shouldn’t be lost in a chat log.

System prompts, agent instructions, specs, AI drafts — the good ones get reinvented in every chat and then forgotten. Mdfoundry is a native Mac home for the community’s prompt library: browse and search it, read every prompt in source or rendered, fork the good ones, and publish your own.

Features

A calm native home for the prompt library.

Source and rendered

Read any prompt as raw Markdown or beautifully rendered — both side by side.

Offline-ready

Your library is cached on your Mac, so it opens instantly — even on a plane.

Search and tags

Find any prompt by keyword or tag, and browse what’s trending in the community.

Fork and publish

Fork any prompt into your own copy, or publish yours for the community to use.

Community tips

See how other people adapt and improve each prompt, right under it.

Native on macOS

A fast, calm Mac app — not a browser tab, not a spinner.
