Your best prompts keep disappearing

You craft the perfect prompt once — then lose it in history, notes, or another tab.

Buried in chat history

The prompt that worked last week is buried under dozens of throwaway chats.

Rewriting the same thing

You retype the same instructions every day instead of reusing what already works.

Tools don’t share prompts

ChatGPT, Claude, Gemini, Grok, Perplexity — your library doesn’t travel with you.

One-click insert

Open the side panel, hit Insert — your prompt lands in the active chat input. No copy-paste dance.
