Frequently Asked Questions

Does UpInbox read my emails on a server?

No. UpInbox runs 100% inside your browser as a Chrome extension. Your email content is processed locally on your device and never sent to any external server. AI classification uses on-device processing or your own API keys, keeping your data completely private.

What AI providers does UpInbox support?

UpInbox supports four AI providers: OpenAI, Anthropic Claude, Google Gemini, and local models. On the Pro plan, you can bring your own API keys from any provider, giving you full control over AI costs and which models process your emails.

How does AI Auto Drafts work?

Auto Drafts analyzes incoming emails and generates reply drafts in your writing style. It learns your tone and common responses over time, so drafts improve the more you use them. You review and edit before sending — nothing sends automatically without your approval.

What is the free tier limitation?

The free tier includes basic AI classification for up to 50 emails per month, a priority inbox, and full sender scoring. Paid plans starting at $4.99 per month unlock more classifications, auto drafts, thread summaries, send later, and bulk cleanup features.

Can UpInbox manage multiple Gmail accounts?

Yes. The Pro plan ($24.99/mo) supports up to five Gmail accounts with unified classification, custom categories, draft profiles per account, and cross-account search. Each account gets its own AI classification and draft settings.
