AI product read Gmail pre-send verification popup that intercepts the Send button and displays TO/CC/BCC recipients grouped by domain for manual confirmation before sending Prevents accidental email mis-sending to wrong recipients by forcing a domain-by-domain visual confirmation step before the Send button becomes available
User composes email in Gmail → clicks Check button (red, replaces Send) → modal popup appears showing all recipients grouped by domain with color-coded TO/CC/BCC labels → user clicks each gray domain group to verify and turn green → when all groups are confirmed green, original Send/Send & Archive buttons appear → user clicks Send to deliver the email
Hides native Gmail Send button and replaces it with a 'Check' button Opens a modal dialog showing all TO/CC/BCC recipients grouped by email domain Color-coded display: TO=red, CC=green, BCC=purple for easy visual distinction Click-to-confirm workflow: each domain group starts gray, user clicks to turn green Send button only appears after all recipient groups are confirmed (turned green) Displays subject line and attachment list for additional pre-send verification
Target users Japanese business professionals sending emails to customers / Users concerned about email mis-sending in corporate/enterprise environments / Gmail users who need an extra verification step before sending important emails ChEx.js is a utility library (~29KB) used for DOM observation; full audit not needed for login/paid decisions as it contains no auth or billing logic No background script exists - the extension is purely content-script based with minimal attack surface Monetization No paid features detected No payment, subscription, license, or upgrade mechanisms exist in the code. All keyword matches for 'paid', 'pro', 'license' are false positives from jQuery library internals (.prop() method calls, jQuery MIT license comments). No billing APIs, no premium feature gating, no payment UI.

Login required No
Reason The extension is a pure content script injected into Gmail pages. It has no authentication UI, no login API calls, no user account system, and no external service communication. It simply modifies the Gmail compose UI. The only 'login' involved is the user's existing Gmail session, which is the destination service's login, not the extension's.
