PromptCase Firefox

PromptCase

Capture the prompts you write in ChatGPT, Claude, Gemini and 10 more AI chat sites, and sync them to your PromptCase account — searchable, taggable, and ready to reuse. Captures only your own prompt text, never AI responses.

Features & Capabilities

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.

Is PromptCase Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PromptCase requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PromptCase is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
