Free Gmail extension · Open beta
They'll know you wrote it. And they'll actually see it — Human Mode proves a person typed your email, then lands it at the top of the Primary Inbox, above the generated noise.
It does it by switching off paste, autocomplete, and AI inside Gmail — for as long as the switch is on.
Every Human Mode email carries an [H] in the subject and a signed line at the bottom. You don't have to swear you wrote it yourself — the proof rides along with the message.
Visible to every recipient, extension or not.
Generated mail is drowning everyone's inbox. A Human Mode email arrives in the Primary Inbox marked Important — not because you paid to be there, but because a person sat down and typed it.
Applies when your recipient runs Human Mode too.
How it earns that — this box is running Human Mode. Type in it, then try to paste.
Written in Human Mode
The switch
One button in the Gmail sidebar. Green means the next email you write has to come from your own hands.
Paste, autocomplete, and generated replies stop working for as long as the switch is on. It's a small amount of friction, applied exactly where it matters.
Why it compounds
The [H] works on anyone. The inbox placement works between people who both run it — so the switch pays off more each time someone you write to flips it on.
Start with the ten people you most want to hear back from. Send them something a machine couldn't have written, and tell them where it came from.
Not an argument against AI
Most email is logistics. Draft it, generate it, template it — nobody is reading it for your voice.
Human Mode is for the ten that aren't: the apology, the pitch, the thank-you, the hard conversation, the note to someone who'd notice if a machine wrote it. Those are worth the extra four minutes.
Getting started
Free, and it only asks for access to mail.google.com.
The Human Mode button appears under Compose. Green means it's on.
Type it out, hit Send, and it goes with the [H] attached.
Before you install
No. Human Mode never reads, stores, or transmits the contents of your messages. It watches one thing — the compose box — and it does that entirely inside your browser.
Turn the switch off for that email. Human Mode is a mode, not a policy — you decide which messages are worth it.
No. Anyone can receive a Human Mode email and see the [H] and the signature. The Primary Inbox and Important flags only apply when they're running it as well.
Nothing. It's free during the beta and there's no account to make.
Gmail on desktop Chrome, today. Other browsers are next.
Get the beta, and send one email this week that couldn't have been written by anyone else.
