Document extraction that remembers.
Send invoices, statements and IDs from any sender, as PDFs, scans or photos. Every layout answers with the same keys, under your own field names, so there is no parser to write. docRefinery learns each layout once, then remembers it.

Printed anywhere, in any words. It lands in the same place.
Each supplier puts the invoice number, the amount and the due date somewhere different, and calls them something different. You get them in the same three fields, every time, named the way you chose.
Your invoice record
- Invoice numberprinted “Invoice No.” HP-2026-0417
- HP-2026-0417
- Amount to payprinted “Amount Due” $9,428.58

Same three fields for every supplier. Dates and amounts written one way. Sample suppliers and values.

Ready to post, one field for review
The first invoice teaches it. The rest are remembered.
Most extractors read your five hundredth invoice as though it were the first. docRefinery learns a sender’s layout once, and every document after starts from what it already knows.

Not in the catalogue? We train your type freeFine-tune a sender’s layout before it runs
Classification tells you what a document is. Fine-tune decides exactly what you get from one sender: the fields only they print, an instruction in your words, the accuracy you need. Approve it once and every document of that layout follows it.
The document is recognised and the fields for its type are lined up. Nothing has run yet.

Field-level governance. Your organisation decides what gets extracted.
An admin defines each field once: a plain instruction, the key it returns as, its type, whether it is required and the confidence it must reach. Every call obeys it. Try it: switch a field or move a threshold.

Built for the teams who live in paperwork
The advantage grows wherever the same senders keep sending the same forms.
Accounts payable
A fixed supplier list sending the same forms every month is the best case this product has.
Your vendor list barely changes. A few hundred layouts cover years of invoices, and each one is learned the first time it arrives.

Why not just ask a general LLM?
It will read a document. It will not tell you when it guessed, where a value came from, or remember the sender next month.
Field accuracy on 2,400 business documents
Invoices, receipts, statements and IDs from 310 senders, 14 languages. Each system scored on the same hand-checked fields.
2,400 documents
docRefinery98.1%
Manual entry, single pass96.3%
General-purpose LLM, prompted91.4%
Template OCR86.7%
Open-source parser81.2%
Scale from 0 to 100%. Fields a system left blank count as wrong; a correct null counts as right.

A general LLM: Can return a plausible value

docRefinery is a document data extraction API, a form of intelligent document processing (IDP). It reads a PDF, scan or photo, OCR included, and returns structured fields with confidence scores. Teams use it for invoice extraction in accounts payable, and for lending, KYC, insurance claims and logistics paperwork. You define the output, every document type answers in the same format, and it learns each sender’s layout once and remembers it.
Invoices, bank statements, receipts, purchase orders, utility bills, passports, bills of lading and more: 20 types in the catalogue, in 70+ languages and scripts. Files can be PDFs, scans or photographs, and spreadsheets (.xlsx, .ods, .csv) on the API where your deployment enables them. Presentations and wider office formats are in development, and a retrieval pipeline is planned; neither is available yet.
Confidence scoring is on by default: fields come back with a score earned from the page, and you set the threshold for each field. A field that is not on the page comes back null rather than a plausible guess. Anything below your threshold goes to a review queue, where a person confirms or corrects it and every change is kept. A correction becomes a suggested fix, tested on that layout’s own documents before anyone applies it.
Through a REST API. POST a file to /v1/runway/async, poll for the run, and read structured JSON. When you want the same fields every time, build a workflow from one sample document and run it by its id. Results export as JSON, CSV or XLSX, and a Chrome extension in early access fills the form in your open tab. API keys are switched on per account, so talk to us when you are ready to connect a system; until then you can run documents in the dashboard. Webhooks are in design, not available yet.
Yes. Private VPC and fully air-gapped on-premises deployment run today on the Enterprise plan, on models hosted inside your network, so a document never has to leave it.
Not yet. Our SOC 2 Type II audit is in progress, with no report yet. SSO is planned for Enterprise and not available yet. We make no data-residency commitments yet.

We’ll remember the rest.
The first document teaches us the layout. Every one after it is recognised on sight.
