Granite

Granite is a document management tool built around a simple frustration: important papers vanish into folders, email threads, and scans you never label. Instead of asking you to name, tag, and file every upload, Granite acts as an AI document organizer that does that work itself. It recognizes more than 110 document types, including W-2s, 1099-NECs, driver's licenses, vehicle titles, home insurance policies, and leases, and it sorts them into collections that form on their own around tax years, vehicles, and vendors.

The part that separates Granite from a plain cloud drive is retrieval. Search works in plain English, so you can ask "when does my passport expire" or "what's the deductible on my home insurance" and get an answer drawn from the actual document, with a citation pointing to the source page. A semantic index and a keyword index both run scoped to your own vault, which is what makes natural-language questions return a specific policy rather than a pile of matches.

So why bother? Because most document apps make you do the sorting. Granite skips that step.

Encryption is the foundation rather than an add-on. Each upload gets its own AES-256 key before it reaches storage, and titles, summaries, and extracted fields are encrypted again inside the database. The catch is flexibility: because Granite reads your documents to organize them, some derived data such as vector embeddings and a digit index stays queryable on the server. That's a deliberate trade of strict zero-knowledge design for a vault that can actually answer questions. Granite also has no monthly plan, so you commit for a year or stay on the free tier. No middle ground.

Getting Started

1. Create an account at granite.co and open your first vault, or poke around the live demo first if you'd rather look before you sign up.
2. Upload documents by dragging in files, forwarding an email, or shooting a photo on your phone. PDFs, JPGs, PNGs, WebP, HEIC, and plain text all work, and folder upload covers bulk imports.
3. Let Granite read each file. It identifies the document type, extracts the key fields, and files it into an auto-collection without any naming or tagging from you.
4. Ask a question or search for a document in plain English, then open the citation to confirm the answer against the original page.
5. Move to Granite Paid when you pass 25 documents, or connect an Evernote or Dropbox archive under Settings to bring an existing library across.
