Persona — AI Email Writer for Gmail

AI email writer for Gmail that sounds human — 7 psychology-built personas, 8 tone dials, one click. Privacy-first. Free to start.

Most AI email tools fix your grammar. Persona engineers how your message lands. Persona is an AI email writer for Gmail built on a simple truth: the hardest part of email was never the words — it's the tone. The same sentence can read as confident or cold, warm or weak, decisive or dismissive, depending on how it's built. Persona treats tone as a science, not a guess. Its writing engine is grounded in published behavioral research — Brown & Levinson's politeness theory, Labov's sociolinguistics, and DISC communication profiles — so every draft is engineered to land the way you intend, on the person you're sending it to. That's why Persona's drafts sound like a human wrote them: they're built the way humans actually communicate. HOW IT WORKS Type your intent in plain words — "push the deadline without annoying them," "say no to this meeting but keep the door open," "ask for the raise." Pick a voice. In one click, Persona drafts the complete email right inside Gmail. Not a template. Not a starting point you'll rewrite. A finished, human-sounding email that says what you meant, the way you meant it. SEVEN PERSONAS. SEVEN DISTINCT HUMANS. Each persona is a fully realized communication character — a pre-tuned behavioral profile, not just a writing "style": • Direct & Decisive — the busy leader. Bottom line first, zero fluff. • Bold & Energizing — passionate and rallying. Gets people excited to act. • Careful & Considerate — thoughtful and diplomatic. Softens hard messages. • Precise & Data-Driven — analytical and rigorous. Every claim backed by facts. • Quick & Casual — reads like a fast Slack message. No ceremony. • Calm & Organized — steady and process-minded. Keeps things moving. • Big Picture & Inspiring — expansive "what if we…" thinking. EIGHT BEHAVIORAL DIALS Under every persona sit eight independent tone dials you can adjust like a mixing board: Assertiveness, Tact, Expressiveness, Warmth, Detail, Urgency, Brevity, and Formality. Slide from consultative to directive, from diplomatic to unfiltered, from data-dense to headline-only — and watch the draft change. This is what email tone control should have meant all along. IT READS THE ROOM Persona reads the Gmail thread you're replying to, so drafts respond to what was actually said. It can also adapt to who you're writing to: the results-first executive who wants one line, the relationship-driven colleague who needs context before the ask, the skeptic who trusts nothing without numbers. IT SOUNDS LIKE YOU Turn on My Voice and Persona learns a numerical fingerprint of your writing — sentence length, greetings, sign-offs, contractions, hedging — from a few samples you provide. Your raw emails never leave your browser; only the fingerprint does. Drafts come out in your voice, not a robot's. PRIVACY-FIRST, BY ARCHITECTURE Privacy isn't a policy page here; it's how the product is built. Names, emails, and phone numbers are stripped before anything leaves your browser — replaced with anonymous placeholders and restored locally after generation, so our servers never see them. The extension reads only the thread you have open (never your inbox or archive), your content is not used to train AI models, and permissions are limited to Gmail. FREE TO START Your first 15 emails are free — no credit card. If Persona earns a place in your day, paid plans add draft history, My Voice, custom personas, and more.
