Drop your paperwork. Granite reads every document the moment you upload, files it correctly, and remembers it indefinitely. Find anything later by asking in plain English.
Granite is a long term doc vault. Legal, medical, business, taxes, etc.
It's NOT a knowledge base. It's a place to drop documents you may never need or only need once or twice. But you should be able to find those docs instantly.
Imagine a title for a vehicle. Or receipts for taxes. Or a purchase agreement from a business transaction. You simply dump all of those docs in Granite and never think about them again...until you do.
No organization. No tagging. No folders. Simple plain english text input to find exactly what you need right when you need it.
"Files it correctly" is doing a lot of quiet work in that one sentence. When a document is genuinely ambiguous — a PDF that's half a tax form and half a personal letter — does it ask me where it belongs, or just pick a home and let me correct it later?
Document vaults that surface the right thing at the right moment have been broken for years. Curious how Granite handles version control — the financial-model templates I publish on Eloquens get updated quarterly, and the gap I keep seeing is users who download v1, fork it, then have no way to back-propagate updates. Is Granite solving for derivative-document drift, or strictly the canonical-version storage side?
"Documents you may never need or only need once or twice — but should find instantly" is exactly the framing missing from most consumer doc tools. The category I keep returning to is mortgage paperwork — most first-time buyers I work with end up with 40-60 PDFs across loan offer, valuation, conveyancer correspondence, insurance, and refix renewal letters, and the cost of not finding them quickly is real (missing a rate-fix window can cost £10-20k over the term). I built MortWise (https://mortwise.netlify.app/) on the analysis side of that journey but the storage problem you're solving sits right alongside it. Curious whether you're planning any time-sensitive triggers — e.g. "this document references a date and you haven't opened it in 11 months" — which is where vault apps usually fall short.
Love the idea! If I see it correctly, everything is stored on proprietary servers? is there a plan to make this work locally + with local LLMs with a one time purchase for Granite? That feels much safer to me personally :)
This solves something I didn't know had a name — I call it 'document anxiety', that feeling when you know you have something important somewhere but have no idea which folder or email thread it's buried in. The plain English search is the key unlock. Does it handle documents in multiple languages or is it English only for now?
