What is Granite
Granite is a digital “vault for every document that matters,” designed to store and manage items like tax forms, IDs, insurance policies, leases, vehicle titles, and receipts. Instead of relying on manual naming, tagging, or foldering, Granite focuses on understanding each document, extracting key fields, and filing it into a structured library that’s easy to browse and retrieve later. It supports common formats (PDFs, scans, phone photos, and forwarded emails) and is built around long-term portability, allowing users to export their entire vault whenever they want.
Key Features of Granite
Granite is an AI-powered, encrypted document vault that accepts documents in whatever format you already have (PDFs, scans, photos, forwarded emails, and common image formats like HEIC). It automatically reads and understands each document, extracts key fields, and files it into a structured library connected to relevant people, vendors, places, vehicles, and tax years—without manual naming, tagging, or foldering. You can later retrieve documents or ask questions in plain English and get answers backed by citations from the source document, with portability features that let you export the entire vault at any time.
Multi-format “Drop” ingestion: Upload PDFs, scans, phone photos, forwarded emails, and common file types (including HEIC/HEIF) individually or via folder upload, so you don’t need to convert documents first.
Automatic document understanding and filing: Granite identifies the document type, extracts important fields, and files it into the right context (e.g., tax year, vehicle, vendor) without requiring you to name, tag, or organize items manually.
Plain-English search and Q&A with citations: Find specific documents (“my 2024 W-2”) or ask questions (“when does my passport expire”, “what’s my deductible”) and get answers sourced directly from your documents with verifiable citations.
Structured library with auto-collections: Documents get a permanent home in a bookshelf-like library, with collections that form around common groupings such as tax years, vehicles, and insurance policies.
Security model focused on privacy and control: Uses two layers of AES-256 encryption (per-upload wrapping plus encrypted metadata/fields) and claims staff don’t browse vaults; emergency access is opt-in, audited, and never silent.
Portability and full-vault export: Documents remain in their original form and you can export the entire vault as a zip, including extracted fields, reducing lock-in risk.
Use Cases of Granite
Personal finance and tax organization: Store W-2s, 1099s, 1040s, receipts, and other tax documents; quickly retrieve forms by year and ask questions like how much was withheld, with citations for verification.
Household and family records management: Centralize IDs, passports, leases, medical EOBs, and insurance policies; query upcoming expirations (e.g., “anything that expires in the next 90 days”).
Small business / freelancer admin: Manage contracts, invoices, receipts, and formation documents; reduce time spent filing and quickly answer questions during bookkeeping or audits by pulling cited details.
Vehicle and property document hub: Keep vehicle titles, registrations, and insurance together with property-related documents; retrieve key fields (like policy deductibles) instantly when filing claims or renewing coverage.
Estate planning and emergency readiness: Maintain a secure, exportable archive of critical documents and enable audited, opt-in emergency access for a trusted person when needed.
Pros
Minimal manual organization: automatic reading, field extraction, and filing reduces tagging/folder work.
Powerful retrieval: plain-English search and Q&A with citations makes it easy to verify answers against source documents.
Security and control: layered AES-256 encryption plus opt-in, audited emergency access and full-vault export improve privacy and portability.
Cons
Annual-only paid plan: pricing is $99/year with no monthly option mentioned.
Free tier limits: capped at 25 documents and 1 GB storage, which may be restrictive for document-heavy users.
Coverage depends on supported document types: while 60+ types are supported and growing, uncommon documents may not be recognized as well.
How to Use Granite
1) Create your Granite vault: Go to https://granite.co/ and sign up to start your document vault (you can begin on the free plan).
2) Upload documents (Drop): Add documents in whatever form you already have: upload PDFs, Word files, images (JPG/PNG/WebP), HEIC/HEIF photos from your phone, or upload a whole folder. You can also forward an email that contains the document.
3) Let Granite process them (Read): After upload, Granite automatically identifies what each document is, extracts key fields, and links it to relevant entities (people, vendors, places, vehicles, tax years). You don’t need to name files, tag them, or manually file them.
4) Verify documents are organized (Filed): Open your library to see each document placed into a permanent home. Review auto-created groupings/collections (e.g., by tax year, vehicle, or vendor) that form automatically.
5) Find documents with plain-English search (Ask → Find): Use natural language to retrieve documents, e.g., “my 2024 W-2” or “anything that expires in the next 90 days.” Granite returns the best-matching document.
6) Ask questions and check citations (Ask → Answer): Ask questions like “when does my passport expire,” “what’s the deductible on my home insurance,” or “how much federal tax was withheld in 2024.” Granite answers using your documents and provides citations so you can verify.
7) Export your vault for portability: When you want a backup or to move your archive, export the whole vault as a ZIP. Documents remain in their original formats, and extracted fields are included alongside them.
8) Choose a plan (optional): Stay on Granite Free (up to 25 documents and 1 GB) or upgrade to Granite Paid ($99/year) for 100 GB storage, no document cap, and emergency access for someone you trust.
9) (Optional) Set up emergency access: If you’re on the paid plan, configure opt-in emergency access for a trusted person; access is audited and not silent.
