Can I use it for Gmail on mobile?

Currently, LLM Hotkey is a browser extension available for desktop Chrome and Edge. Mobile support is on our roadmap for future releases.

Is my email data safe?

Absolutely. LLM Hotkey processes text locally and only sends the selected text to AI models when you request it. With BYOK mode, requests go directly to your chosen AI provider. We never store or log your emails.

What AI models power the email suggestions?

By default, we use Google Gemini 3.0 Flash for fast, high-quality responses. Pro and BYOK users can choose from OpenAI GPT-4, Claude, or custom models.

How many emails can I write per day?

Free users get 10 AI requests per day. Pro users get 300 requests per day. BYOK users have unlimited requests using their own API keys.

The Gmail Writing Struggle

Email takes up 28% of the average workday. You stare at blank compose windows, rewrite the same phrases, and second-guess your tone. Copy-pasting to ChatGPT breaks your flow and wastes precious time.
