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.

What does an AI email assistant actually do?

Who is this AI email assistant for?

Inbox Ninja is built for founders, operators, executives, and small teams who live in Gmail and need faster triage, cleaner follow-up, and better reply drafting without losing their voice.

Why this page exists

Most AI email assistants promise speed. The real job is reducing cognitive load.

Plenty of tools help you write faster. Fewer help you decide faster. If your inbox is the front door to the infinite workday, the problem is not just typing replies. It is constantly switching context, decoding who owes what, and figuring out what deserves your attention.

Inbox Ninja is positioned around that gap. It is an AI email assistant for Gmail that turns unread chaos into a decision brief: what changed, what is blocked, what needs a reply, and what can wait until later.
