How does Inbox Ninja keep my emails private?

Inbox Ninja runs locally on your Mac. Your emails never leave your device - only the specific content you're working with is processed. OAuth connection to Gmail can be revoked anytime.

Will replies sound like me?

Yes. Inbox Ninja learns your communication style from past emails. Draft replies match your tone, formality level, and typical response patterns.

Does it work with Google Workspace?

Yes. Works with personal Gmail and Google Workspace accounts. Same OAuth flow, same privacy guarantees.

How is this different from Gmail's smart compose?

Gmail suggests sentence completions. Inbox Ninja writes full contextual replies, summarizes long threads, and triages your entire inbox to surface what matters. It's the difference between autocomplete and an assistant.
