IDX does two things, both on your phone. VERIFY AN ID Scan a driver's licence, ID card or passport, take a selfie with a quick liveness check (a blink and a head turn), and see exactly what was read and how it compares: the face on the ID against your selfie, every field read from the document, and the front of the card checked against its barcode. No account. No install needed when it is opened from an IDX link or App Clip Code. SAY WHAT YOU NEED On iPhones with Apple Intelligence, tap "Think out loud" and talk. IDX writes down what you said, then turns it into a short note: a title, the gist, what you need from IDX, a section for each subject, and your next steps. Check it, add your name and email (or scan your ID to fill in your name), and send it to IDX by email. PRIVATE BY DESIGN - Your ID, selfie and voice are processed on your phone, using Apple's on-device speech and language models and IDX's own on-device document and face technology. - Nothing is uploaded. There is no account and no tracking. - The app keeps your voice notes and ID checks only on your phone, protected, and you can delete any of them or all of them in History. The App Clip keeps nothing. - The only thing that ever leaves your phone is the email you choose to send. Made in Vancouver by IDX Studios.
