Stop the scams.
Skip the AI pitches.
Inbox Hero checks every new Gmail message for scams and risky links or attachments. It files newsletters and promos away and shows how likely each email was written by AI.
Start with your email
We email you a 6-digit sign-in code. No password needed.
Check your email
We sent a 6-digit code to your inbox. Enter it here to sign in on this device.
Next you connect the inbox you want sorted: Gmail, iCloud, Yahoo or other email. Inbox Hero works once one is connected.
Or tap the link in the email. The code and the link work once, for 15 minutes.

Google will ask to read and organize your Gmail so we can catch scams. We never delete mail on our own or send without your tap.

Scam emails are written by AI now, so typos no longer give them away.
So Inbox Hero ignores how an email reads and checks what a scammer can't fake: who really sent it, where its links go, and what its attachments are.
Sender verification
Reads each message's authentication results (SPF, DKIM, DMARC) and flags mail whose display name, reply-to address or domain doesn't match who it claims to be.
Link inspection
Checks the links in new email against public lists of known phishing sites. The lists sit on our own server, so your links are never sent to a list provider. Also flags look-alike domains, raw IP addresses, shortened links and buttons that show one site but go to another.
Attachment checks
Catches “invoices” that are really programs (invoice.pdf.exe), files that run when opened, macro-enabled Office files, attached fake sign-in pages and password-locked archives. Attachments are judged by name and type and are never opened or downloaded.
AI intent review
Anything suspicious gets a second look from an AI that judges intent, not writing quality: credential theft, fake invoices, gift-card, wire and crypto requests, CEO and vendor impersonation.
Quarantine, not deletion
Clear threats, and mail with several warning signs from a sender that fails email checks, move into InboxHero/Fraud where you can review them. One tap brings a message back, and Inbox Hero learns from it.

See which emails were written by AI.
Anyone can now send you a hundred “personal” notes a day. When you open an email, Inbox Hero shows how likely it was written or polished by AI, so a mass-templated pitch is easy to spot. It never moves a person's email because of it.
A score, not a filter
A small “92% AI” mark sits on the email when you open it. Mail from people stays in your inbox either way.
Judged on the writing
An AI reads the text and estimates how much of it was written by a model. Short notes are too short to judge, so they get no score.
Yours to turn off
The score is on by default. Turn it off in Settings any time.
Quick question about your growth plans

- First message · you've never replied
Hi Mike, I hope this finds you well! I came across your company and was really impressed by the work your team is doing.
We help companies like yours unlock scalable growth with done-for-you outbound. Would you be open to 15 minutes next week?
P.S. Just bumping this to the top of your inbox in case it got buried.
Know who's really emailing you before you act.
Inbox Hero checks each new email. When one deserves a second look, it gives it a verdict, shows you the signals behind it, and lines up the next step, so one tap does the work.
Three meters, at a glance
Scam risk, AI-written and Relationship strength: how much you've actually emailed this person, how fast you reply, and when you last talked.
Why, in plain words
The specific signals behind the verdict, like a bank account that changed since the last invoice or a reply-to address that doesn't match. Plus one line on what the sender wants.
One tap, Inbox Hero does it
Draft a reply. Hold a payment request and draft a check-in. Move it to Fraud. Mark it safe. Add the deadline to your calendar. Nothing is sent until you tap.
The verdicts
- Likely scam
- Check before paying
- AI-written pitch
- AI-assisted, known sender
- Trusted contact

Invoice #2291: updated payment details
InboxInboxHero/Check before payingA vendor you know, but the bank details changed. Confirm by phone before paying.
- Your last 4 invoices from Brightline went to an account ending 4417. This one asks for 9032.
- Reply-to is dana.ortiz.billing@gmail.com, not her company address.
- Sent at 3:12 am, outside her usual hours.
Pay $18,400 to a new bank account by Friday.
Hi Mike,
Please find attached invoice #2291 for October production ($18,400). Note that we've moved banks, so please use the updated details below for this and future payments:
Account name: Brightline Studio LLC
Routing: 121000358
Account: ****9032
Could you process by Friday? Thanks so much!
Dana
One verdict per email, only when it's worth one.
Why: look-alike domain coastline-bank-secure.co, failed DMARC, and the “Verify now” button goes to a raw IP address.
Why: first contact from a stranger, template phrasing, flattery then a generic “15 minutes next week?” ask.
Not a warning. Written with AI help, but you've traded 64 emails and he replies within a day.
What she wants: your approval on the Q4 budget by Thursday.

The panel inside the email
Turn this on and Inbox Hero adds the panel to the top of the flagged email itself, right inside Gmail. The original is kept in Trash for 30 days. Off by default.
Set it up in a minute. Keep using Gmail.
Inbox Hero works in the background on the inbox you already have. Sign up once and the filtering just runs: you never have to open our app. Your folders show up as ordinary Gmail labels on every device.
- Step 1
Sign in and connect Gmail
Start with your email, no password to share. Google will then ask you to allow three things: read and organize your Gmail, send email you approve, and view (not change) your calendar so replies and reminders know your schedule. iCloud, Yahoo, Fastmail, AOL and other IMAP mailboxes can be added with an app password.
- Step 2
Every new email is checked, then sorted
Threats go to Fraud first. Mail from people stays in your inbox. Bulk mail is sorted by what it actually is:
NewslettersShoppingNotificationsLater+ your own folders - Step 3
Correct it once and it learns
Drag a message back to the inbox and that sender stays there. Move one into Shopping or Newsletters and it files that sender there from then on.

Quick Reply
Inbox Hero drafts replies that match how you write: your greeting, your sign-off, your length. Glance, tweak and send. Nothing goes out until you tap send.
Ask your inbox
Ask in plain English: what you're waiting on, when a package arrives, what someone said last month. Inbox Hero reads your mail and answers.
Daily brief
Each morning at 9 your time, a short email with what was filed, what was caught and replies ready to confirm. Turn it off with one click.
Built to be trusted with your email.
Gmail stays the source of truth. If Inbox Hero ever went down, your email keeps working exactly as it does today.
- Encrypted at rest. OAuth tokens and app passwords are stored with AES-256-GCM. We never see your Google password.
- Minimal permissions. Read and organize, plus send only when you tap send.
- Attachments never opened for scam checks. Fraud checks read headers, links and attachment names and types.
- Email can't steer the AI. Message content is treated as untrusted data, so a crafted email can't hijack it.
- Disconnect anytime. Disconnecting deletes your stored access immediately.
- Per-account isolation. Your mail is never mixed with anyone else's.

The straight answers.
Does Inbox Hero delete my email?
No, never on its own. It moves mail between Gmail labels: threats go to InboxHero/Fraud, bulk mail to folders like Newsletters and Shopping. Everything stays in your account, and every move is one tap to undo. The only thing that deletes is your own Delete button, which moves an email to Trash with Undo.
Will it send email on my behalf?
Only when you approve it. Inbox Hero drafts replies, but a reply goes out only after you tap send in the app or confirm it from your daily brief.
Do I have to use your app?
No. Plenty of people sign up just for the filtering. It runs in the background and you keep reading mail in Gmail on any device. Scams go to a Fraud folder and clutter goes to ordinary Gmail labels. Our app is there if you want answers, drafts and a morning brief.
Will it catch every scam?
No filter catches everything. Inbox Hero is strict about what it quarantines, because moving a real email is worse than leaving a suspicious one where you can see it. Treat any request for money, passwords or codes with care.
Which email providers work?
Fraud protection runs on Gmail, Google Workspace and IMAP mailboxes (iCloud, Yahoo, Fastmail, AOL and others): scams are moved into a Fraud folder on all of them. In-email Insights run on Gmail and Google Workspace. IMAP mailboxes are connected with an app password and also get sorting, Ask your inbox and Quick Reply.
Does it move AI-written email?
No. Mail from a person stays in your inbox, even when it reads as AI-written. When you open an email, Inbox Hero shows how likely it was written by AI (for example "92% AI"), so a mass-templated pitch is easy to spot and skip. You can turn the score off in Settings.
What are Inbox Hero Insights?
When a new email deserves a second look, Inbox Hero gives it a verdict (Likely scam, Check before paying, or Be careful), three meters for scam risk, AI writing and how well you know the sender, the reasons why, and one-tap actions. You see it in the Inbox Hero app and in your daily brief. If you turn on the optional setting, Inbox Hero also adds the panel to the top of the flagged email in Gmail and keeps the original in Trash for 30 days. Insights run on Gmail, and they're guidance: nothing is sent unless you tap.
What does it cost?
It's free for 14 days, with no card needed. Near the end of the trial Inbox Hero asks if you want to keep everything; if you add a card, nothing is charged before the trial ends and we email you 7 days before the first charge. If you don't, you move to the free plan: scam and phishing protection keeps running on your first mailbox. After the trial it's 27¢ a day ($99 a year), or $27 a quarter or $10 a month for your first mailbox, plus $5 a month for each extra one.
Nothing during the beta, and there's no card to enter. The planned price after beta is 27¢ a day ($99/year), or $10/month per mailbox.
Give your inbox a bodyguard.
Free for 14 days, no card needed. Connect your Gmail and the first check runs right away. Google will ask for Gmail access and read-only calendar access; you can disconnect any time.
