Independent measurement bench

We measure OCR accuracy.
Vendors don't get to.

Every OCR / Document-AI API below is scored by running the same public-domain document set through it and computing the Character Error Rate ourselves, alongside measured latency. The numbers are first-party measurements — and sponsors cannot edit them.

Method: FUNSD (public-domain US-gov scanned forms) + a Project Gutenberg / IA printed-page slice · scored with CER (jiwer / Levenshtein) vs transcribed ground truth · latency = median of 5 runs · v1-illustrative

⚠ The numbers below are ILLUSTRATIVE samples. The method is real and reproducible — replace these with measured numbers after running the benchmark with real API accounts. No real accounts, keys, or money were used.
