About

PromptMate — Your personal prompt library for ChatGPT and Claude (Beta)

Save time and stay consistent with your most effective prompts. PromptMate adds a sidebar to ChatGPT and Claude that lets you:

- Save frequently-used prompts with Tone and Output Format presets
- Insert them into the chat input with one click
- Edit and customize prompts on the fly
- Sync prompts across devices via your own Google Drive
- Track how often you create, use, and copy prompts (local stats only)

How your data is stored
PromptMate uses Google Sign-In to sync your prompts to a hidden, app-only folder in your personal Google Drive. This folder is sandboxed — PromptMate cannot see or modify any other file in your Drive. No backend server is involved; prompts move directly between your browser and your Drive.

Usage counters (created, used, copied, edited, deleted) are stored on your device and never leave it unless you click "Share Analytics", which copies a summary to your clipboard.

Who it's for
Students creating study guides, developers optimizing code requests, and anyone fine-tuning prompts for ChatGPT or Claude.
