How AI Receipt Scanning Works
A technical-but-friendly tour of what happens when you snap a photo of a receipt and an AI converts it into structured expense data.

From paper to structured data
When you snap a receipt, the image is processed through layers of computer vision and language models — first to extract raw text via OCR, then to interpret what each field actually means.
The pipeline
- Capture — image enhancement, perspective correction, glare reduction.
- OCR — extracting characters and lines.
- Parsing — identifying merchant, total, tax, line items, date.
- Classification — assigning a category.
- Validation — flagging anything uncertain for a one-tap fix.
Why it matters
A few seconds of AI replaces minutes of manual data entry. That compounds quickly when you're tracking dozens of receipts a month.
