There’s a better way to pay for PDF accessibility
Traditional accessibility vendors charge $0.25–$0.50 per page. At 500,000 pages, that’s $125,000–$250,000 per year. SentraCheck’s BYOK model brings the same corpus to under $35,000 all-in.

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.
