Document AI

Which document AI tool is actually most accurate?

We gave every serious extraction tool the same 50 documents and the same schemas, scored the output field by field, and published all of it. Real invoices, bank statements, a rotated scan, a spreadsheet, a Hebrew payslip. If a tool could not read a file, that scored zero rather than quietly disappearing from its average.

Reviews

What each product is good at, where it fails, and the documents where a lower-ranked tool beats a higher-ranked one.

Scoring

A file it cannot read is a zero.

Vendors publish accuracy on the documents they could process. We score the ones they choked on too, which is why our numbers sit below the marketing ones and why the gaps between tools look different here.
