Use case / Document processing agents
See which page each field came from.
Extraction agents read invoices, contracts and forms, and one wrong field can slip through. Trace page to field so every value can be checked against where it came from.

- Linked
- Reviews

Extraction record
Each field, with its page.
Every file becomes a trace, so any filed value has a history.
Page splits show which pages were hard to read.
Each field is a span with the text the model saw.
A wrong or low-confidence field is flagged on its page.
Review handoffs are recorded, so you see what people fixed.
- 01ok
File received
A 6 page supplier invoice, PDF.
- 02ok
Pages split
Page 3 is a scan with low contrast.
- 03ok
Fields extracted
Eleven fields, one with low confidence.
- 04misread
Total read wrong
The subtotal was read as the total.
- 05ok
Sent to review
The field is queued for a person.
The failure to catch
An invoice total read from the wrong line, and filed as correct.
Trace extraction from page to field so a misread amount or a missed clause points back to the step that got it wrong.
What Tracify watches.
Pages read
Recorded on every run, so it can be searched, compared and alerted on.
Fields extracted
Recorded on every run, so it can be searched, compared and alerted on.
Confidence per field
Recorded on every run, so it can be searched, compared and alerted on.
