For many years, axes4 has been offering the PDF Accessibility Checker (PAC) – the standard tool for checking individual PDF documents for accessibility. PAC is a free Windows application widely used by organizations around the world.
axesSense builds on the same trusted checking routines as PAC, but allows you to check large numbers of documents automatically and at scale. Unlike PAC, axesSense requires a license (API Key) from axes4.
axesSense is available in two editions: On-Prem and Cloud.
axesSense Cloud is a hosted solution provided by axes4. Through our Web API, you can upload PDF documents and have them validated against the Matterhorn checks.
