PromptCase

Your prompt library across ChatGPT, Claude, Gemini and other AI chat sites — save what you write, reuse it where you type.

PromptCase saves the prompts you write in AI chat tools to your own searchable library, so a prompt you got right once is never lost in a scrollback again. HOW IT WORKS: Connect the extension once with a token from your PromptCase dashboard. After that, prompts you send on any supported site are captured in the background and synced to your account, where you can search, tag, and organise them into folders. REUSE THEM WHERE YOU TYPE: Type // in the chat box to search your saved prompts and drop one straight into the composer — no copy-paste, no leaving the page. An optional AI "enhance" for your current draft is available once you turn on AI features in your PromptCase dashboard. WHAT IT CAPTURES: Only the prompt text you write yourself. PromptCase never stores AI responses, and never reads pages other than the supported chat sites listed below. SUPPORTED SITES (13): List is available on https://promptcase.dev/about CONTROLS: Turn capture on or off per site, or globally, from the settings page. • See exactly what is queued and what has synced. • Disconnect at any time — the extension holds no data once disconnected. REQUIRES A PROMPTCASE ACCOUNT: The extension syncs to a PromptCase account. Sign up at https://promptcase.dev SUPPORT Questions or a site not capturing? Write to support@promptcase.dev
