Confirm: Email & Message Checker

Catch mistakes before you hit Send, Post or Submit. Missing attachments, wrong dates, tone, privacy slips and more, in any text box.

Spellcheck catches typos. Confirm catches the mistakes that actually cost you: the attachment you said you attached, the "Friday the 27th" that's really a Sunday, "Hi Sara" to someone called Sarah, your phone number in a public comment, the API key you pasted into a chat, the [NAME] you meant to fill in. It works in the text box you're already typing in: email, chat, social posts, comments, job applications, contact forms and almost anywhere else you write. HOW IT WORKS 1. Write as usual. A small badge in the corner of the text box shows a tick when all is well, or a number when there is something to look at. 2. Click it to see what Confirm found, why, and a suggested fix. Replace it in one click, or dismiss it. 3. Press Send. If something important is still wrong, Confirm pauses the send and tells you. "Send anyway" is always one click away. WHAT IT CHECKS • Attachments mentioned but missing • Dates: weekday and date that disagree, dates that don't exist • The wrong name in your greeting • Personal details in public posts; passwords, keys and card numbers anywhere • Placeholders left unfilled, broken or missing links, email-address typos • Caps lock, repeated words, stray punctuation • With AI review: grammar, clarity, tone, missing context, unanswered questions, contradictions and numbers that don't add up • Commitments you're making ("I'll send it by Thursday") FREE AND PREMIUM • Free: unlimited local checks and 10 AI reviews a day. • Premium: unlimited AI reviews, tone and missing-context checks, replies checked against the thread, full commitment tracking. • Premium will be a one-time $4.99, no subscription. Purchasing opens after launch; until then the trial gives you everything. • Launch offer: new accounts get 30 days of Premium free from September 25 through October 25, 2026 (UTC). After that, new accounts get 7 days. No card needed. PRIVATE BY DESIGN • AI review runs on Chrome's built-in AI, on your own computer. What you write is never uploaded, stored or sold. • Password, card and one-time-code fields are never read. • Passwords, keys and card numbers are masked before even the on-device AI sees them. • You choose which sites Confirm works on, and can turn it off on any site in one click. • No ads. No tracking. Sign in with Google only so your allowance, purchase and settings follow you. REQUIREMENTS Desktop Chrome. Local checks work everywhere. AI review needs Chrome 138 or newer on a computer that can run Chrome's built-in AI, and a one-time download that Confirm walks you through.
