Your best prompt always disappears right when you need it

It lives somewhere between a ChatGPT thread, a .cursorrules file and a Markdown note you'll never open again. So you rewrite it from scratch — and lose the version that actually worked.

🗂️

Prompts scattered everywhere

Chat threads, rules files, gists and notes. No single place to look.

🔁

Rewrite the same prompt again

The version that worked last month is gone, so you start over.

🧨

Leak a key into a chat

A stray API key or .env line slips straight into an AI tool.

Everything your prompts need to become assets

  • Save every prompt with tags, scene, tool and model. Lightning-fast full-text search brings back the exact prompt that worked last month in seconds.
  • Every edit is saved automatically. Compare two versions side by side, restore an older one, add change notes and mark the best version per model — it's Git for your prompts.
  • Turn a one-off prompt into a reusable template with {{variables}}. Add defaults and descriptions, fill them once, and generate the final prompt — ready to paste into any tool.
