Better Results Through Better Technology

In an age of digital transformation, ensuring accessibility for people with disabilities is no longer optional. It is necessary.
PREP’s sophisticated AI-powered automation technology and a fierce commitment to user experience enable easy, affordable, and scalable document remediation for accessibility.

What Makes PREP Different From Other PDF Accessibility Tools?

Skip the Tedious with Cutting Edge AI

Powered by sophisticated AI-based auto-tag detection, PREP’s document remediation software accelerates the time-consuming and tedious process of tagging nested lists and table of contents (ToC), saving you more than 60% turnaround time. In addition, its intelligent system gets more accurate over time, giving you better results with every review and validation.

Scalability Made Affordable

Document remediation at scale can be complex and resource-intensive, resulting in high costs. PREP’s advanced AI helps you deliver exponential cost savings by reducing the manual time spent in document remediation, whether done in-house or outsourced to our team at Continual Engine for scale remediation.

Reliable, Intuitive, Anywhere Access

PREP’s document remediation platform is cloud-based, allowing easy access at any time, from anywhere, simply by using a browser. It also means you do not need to install any software. New features are available instantly through automatic upgrades.

Accelerating Accessibility with Collaboration

Whether it is assigning documents for faster remediation or driving accessibility across the organization, PREP’s collaboration features accelerate accessibility.

Look Beyond Compliance. Achieve Inclusion!

PREP’s remediation output is 100% compliant with ADA/508/EAA regulations and WCAG 2.2 AA guidelines. This not only helps you avoid any lawsuits but also promotes diversity, equity, and inclusion (DEI) initiatives, thereby improving engagement and opening doors to new business opportunities.

Quick Onboarding and Low Learning Curve

PREP’s human-centred design makes it exceedingly easy for beginners, part-time employees, or new users to get started instantly. No prior remediation knowledge is necessary. PREP’s PDF remediation software offers more power to accessibility experts while effortlessly onboarding new users or non-experts.
