Live demo, invoice automation

An invoice lands. Five steps later it's a clean row.

AI reads the PDF, code validates it, duplicates get blocked, a human only sees the edge cases.

Watch one go through

Run a sample, or upload your own invoice (PNG, JPEG or PDF). The saved samples answer instantly; your own upload goes to the live model.

The live model hit today's free-tier quota. The saved samples below still work.

The samples are saved runs: instant, and they use no AI tokens. Upload your own sends that single file to the live AI, so give it a few seconds, and you get 3 free tests a day. We don't store it: your file is read once, kept in your browser for this session only, and never saved on our side.

How it works

The model reads. Code decides.

The money path is plain code, not model judgement. That's on purpose. You want the same answer every time.

Alert / human review

The model only reads

It pulls vendor, number, date and totals out of the image or PDF, and rates how sure it is on each field.

The rules decide

Code checks the required fields, the date range, whether the totals add up, and whether you've seen this invoice before.

People see edge cases

Clean invoices get logged on their own. Duplicates, broken totals and low-confidence scans stop for a quick human look.

In your business

Where this plugs in

Straight from your inbox

Point it at a Gmail or Outlook label. Invoices get picked up the moment they arrive, nothing to forward by hand.

Own it in n8n or Make

Prefer a visual workflow you control? The same five steps drop into n8n or Make. Or keep it as plain code.

Not just invoices

Receipts, purchase orders, delivery notes. The read, validate and route pattern is the same for all of them.
