About

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.
