AI that lives where you already write
Most "AI for email" lives in another tab. You write a prompt over there, copy the result, switch back to Gmail, paste, and clean up the formatting. Persona is a Chrome extension that runs inside Gmail — the button sits right in the compose and reply window, so your draft appears exactly where you need it.
One click, in the message you are already reading. That is the whole point: the fastest AI email writer is the one you never have to leave Gmail to use.
It reads the thread, so the reply actually fits
A generic AI draft ignores what was said three messages ago. Persona reads the Gmail thread context — who asked what, what was promised, the last open question — and writes a reply that responds to this conversation, not a blank page.
- Context-aware replies. The draft answers the actual email in front of you, referencing the open thread.
- One click, in place. The reply lands in the Gmail compose box — nothing to copy, nothing to paste.
- Tone you choose. Seven personas and eight behavioral dials let you set how the message lands before you send it.
Tone, not grammar — set how you land
Spell-checkers make an email correct. Persona engineers the tone, power read, warmth, and urgency. Inside Gmail, you pick a writing persona and turn eight dials — assertiveness, warmth, urgency, brevity, formality and more — until the reply lands the way you intend.
- Turn down assertiveness to soften a "no" without sounding weak.
- Turn up urgency on a sales reply where a slow, flat answer loses the deal.
- Use My Voice to draft in your own style, learned from emails you actually write.
Private by design
A Gmail AI extension sees sensitive threads, so privacy cannot be an afterthought. Names, email addresses, and phone numbers are stripped inside your browser before anything leaves it — the model never receives the personal details in your thread. See our privacy approach.
