Features & Capabilities

GemType checks your writing on every website and fixes it with one click — like Grammarly, but powered by Google's Gemini AI and your own free API key. No account, no subscription, no company server in the middle.

HOW IT WORKS ✔ Type anywhere — Gmail, LinkedIn, X, Reddit, GitHub, any text field ✔ Pause for a second — mistakes get wavy underlines ✔ Click an underline — accept the fix (Ctrl/Cmd+Z always undoes) ✔ After each fix, the whole sentence is automatically re-checked

REWRITE ON DEMAND Select any text and choose: Improve, Fix grammar, Shorten, Formal, or Casual. Also available from the right-click menu. Rewrites keep your meaning — corrections keep your exact wording.

BRING YOUR OWN KEY (FREE) GemType uses your personal Gemini API key from Google AI Studio (aistudio.google.com/apikey — free tier, no credit card). Requests go directly from your browser to Google. We never see your text or your key.

PRIVATE BY DESIGN • No accounts, no tracking, no analytics • Your key and settings stay on your device • Your text is sent only to Google's Gemini API • Turn GemType off globally or per-site in one click

WORKS IN YOUR LANGUAGE Auto-detects the language you write in, or pin one in settings.

Is GemType — AI Writing Assistant 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.

GemType — AI Writing Assistant requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

GemType — AI Writing Assistant is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
