<strong>Confidence Scores.</strong> Get per-word and per-page confidence scores that help you flag sections needing human review and route low-confidence regions to verifiers while auto-approving the rest.
<strong>170 Language Support.</strong> Process documents in 170 languages across 10 language groups with strong performance on rare and low-resource languages that other systems struggle with.
