About SlotOwl — Appointment Monitor

Get the slot. Skip the queue. SlotOwl is a free Chrome extension that watches government appointment portals from inside your own browser session and alerts you the second a slot opens — by desktop notification, email, or push notification on any device you've paired. WHAT IT MONITORS • US visa interview slots (consular appointments) • Schengen visa appointments • INM Mexico — cita / temporary & permanent residency • Global Entry & TSA PreCheck interview slots • US passport renewal appointments • Any government scheduling portal that loads in Chrome HOW IT WORKS 1. Sign in once with Google. 2. Open the appointment portal you care about. 3. Hit "Start" — SlotOwl polls the page every couple of minutes from your own logged-in session. 4. The instant a slot appears, you get an alert and the extension auto-pauses so you can claim it. ALERT CHANNELS • Desktop notification (always on) • Email (Resend-backed, no spam) • Cross-device push (scan a QR with your phone or tablet) PRIVACY-FIRST BY DESIGN • No headless scraping. No proxy IPs. No bots pretending to be you. • Polling happens in your own Chrome tab, in your own session. • We never see your portal cookies, your form fields, or your appointment details. • The only thing the backend stores is the workflow you defined and a tiny "available / not available" status used to fan out alerts. • Optional alert-time screenshot (your trigger, your choice) is private to you and auto-deleted after a short retention window. FREE WHILE WE'RE IN BETA 50 alerts per month per account. No credit card. No subscription. Pricing will arrive later — early users will be grandfathered.
