There’s a better way to pay for PDF accessibility
Traditional accessibility vendors charge per page, so the bill grows with every upload. SentraCheck’s flat-subscription BYOK model brings the total cost of a large corpus down dramatically — request a demo for a quote sized to your agency.

How SHA-256 deduplication saves money
Every PDF uploaded to SentraCheck is fingerprinted with a SHA-256 hash. If we’ve ever processed an identical document — for any customer, anywhere on the platform — we serve the cached result instantly at zero AI cost.
For government agencies, this is significant. City council agendas often appear identically across departments. State agency templates get posted by hundreds of entities. Staff reports follow common formats. Our analysis shows 15–25% of documents in a typical city corpus are exact duplicates.
With per-page vendors, you pay for every upload. With SentraCheck, duplicate processing costs $0.
What drives the BYOK savings at 500K pages
Traditional per-page vendors charge for every upload at the same corpus size — no dedupe, no archive-exempt discount. Request a demo for a quote sized to your corpus.
