See which emails were written by AI

Anyone can now send you a hundred "personal" notes a day. Inbox Hero recognises cold pitches written or mass-templated by AI and moves them out of the way, so the people you actually know stand out.

The AI Outreach folder (Gmail)

An AI score on each email

Inbox Hero's Insights show how likely an email is to be AI-written, next to its scam risk and how well you know the sender, so a fluent message from a stranger doesn't pass for a friend.

Never filed as AI Outreach: people you've emailed, replies in your threads, mailing lists, receipts and notifications. The AI Outreach filter is a switch you turn on per Gmail account.

On an iPhone Duo? Inbox Hero uses both screens: your inbox on one, the email and a reply drafted in your voice on the other. See it on the Duo.

Free for 14 days, no card. Then 27 cents a day ($99 a year).

Gmail access reviewed and approved by Google after an independent security assessment.

Frequently asked questions

Can you tell if an email was written by AI?

Inbox Hero estimates how much of an email reads as AI-written and, on Gmail, files AI-written cold pitches from strangers into an AI Outreach folder. It is an estimate, not proof.

How do I block cold sales emails?

Turn on the AI Outreach filter. First-contact pitches from strangers move to their own folder, and people you know are never filed.

Will it hide real email from people I know?

No. It only looks at first contact from strangers, and anything you move back is never filed again.
