About this extension
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, organise into folders, and copy them for reuse.
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):
ChatGPT, Claude, Gemini, Microsoft Copilot, Perplexity, Mistral (Le Chat), HuggingChat, You.com, Poe, Grok, Bolt, Lovable, and Replit.
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
