About

Granite

Features
Read full description

Granite (granite.co) is a document vault for iPhone. Scan or drop in a receipt, an insurance policy, a tax form, or a passport, and Granite reads it, works out what it is, pulls out the dates and amounts that matter, and files it so you can find it again. CAPTURE Scan a page with the camera and Granite straightens and crops it for you. Share a file into Granite from Files, Mail, or Safari. Everything you add is read and filed the same way, whatever door it came through. FIND IT LATER Search reads the words inside every page, not just the file name. Ask a question in plain English, like "what did I pay for car insurance last year", and get an answer with the document behind it. STAY AHEAD OF DATES Granite pulls renewal and expiration dates off your documents and tells you before they pass, so a lapsed policy or an expired passport is never a surprise. ORGANIZED WITHOUT THE WORK Documents group themselves into collections, and into the people, cars, homes, and accounts they belong to. There are no folders to design and no naming scheme to keep up. WHAT PEOPLE KEEP IN GRANITE Tax forms and W-2s. Insurance policies and cards. Passports, IDs, and Social Security cards. Receipts and warranties. Medical records and explanations of benefits. Car titles, deeds, closing documents, leases, contracts, and invoices. YOURS, AND PRIVATE Every file is encrypted. Face ID or Touch ID locks the app. You can export everything you have put in, at any time, in a format you can read without us. Granite Free holds 25 documents and 1 GB. Granite Paid is an annual subscription that lifts the limits and unlocks Ask. Terms of Use: https://granite.co/terms Privacy Policy: https://granite.co/privacy
