Frequently asked questions

Can I use ChatGPT inside Gmail with Krater?

Yes. Krater connects to Gmail and runs GPT-5, Claude Opus 4, Gemini 3 Pro, and 350+ other models against any thread. Plans start at $20/month.

Is Krater a Gemini in Gmail alternative?

Yes. Gemini in Gmail requires Google Workspace Business Standard ($14+/user) or the Gemini add-on. Krater is $20/month, model-agnostic, and works with any Google account — personal Gmail included.

Will Krater send emails on my behalf?

Krater drafts replies for you to review and send. You can also approve full automations — for example, auto-replying to specific labels — but nothing sends without an action you set up.

Does this work with personal Gmail accounts?

Yes. Personal Gmail and Google Workspace accounts both work. Personal accounts do not need admin approval.

Will my email content be used to train AI?

No. Krater never trains on your data. Email content is sent to your chosen model only for the specific request and never retained for training.

How do I connect Gmail to Krater?

Open Krater, go to /additions, search Gmail, click Connect, and complete the Google OAuth flow. Takes about 30 seconds.
