Paperstack does the work you keep meaning to do — automatically.
Point your camera at any receipt — paper, thermal, or handwritten — and Paperstack parses it in seconds. Merchant, date, total, line items: all extracted, all searchable.
Paperstack automatically detects warranties buried in receipts and product docs. Set it once and receive alerts at 30, 14, and 3 days before expiry — never scramble for a receipt again.
Share your stack with up to 5 household members. Receipts, warranties, and spending history are all visible to your crew — so whoever bought it can find it.
Powered by Claude Haiku, Paperstack handles the trickiest receipts: faded thermal rolls, multi-page invoices, handwritten slips from the farmers market. If there's a total, we'll find it.
Your data is yours. Export a clean CSV for your accountant, a formatted PDF for a warranty claim, or a full ZIP archive of everything — whenever you want, with one tap.
Find any purchase in your history by merchant name, item description, amount, or date range. Full-text search across every receipt in your vault, available offline.
Not all receipts are created equal. Paperstack's OCR engine is trained on the full range of what gets handed to you at checkout — including the receipts you were sure would be unreadable.
The warranty is always in the last place you look — usually after it's expired. Paperstack reads purchase dates and warranty terms automatically, then reminds you while there's still time to use them.
Who bought the blender? When does the fridge warranty expire? With Paperstack, the whole household has the answer — not just the person who happened to be at checkout.
