Continual Engine, an artificial intelligence (AI) technology company with a deep commitment to accessibility and learning developed PREP to empower individuals, institutions and organizations in making accessibility within easy reach. 

A casual dinner conversation with friends started Continual Engine’s journey in leveraging artificial intelligence, deep learning, machine learning, automation, vision technologies, and more to bring inclusion with affordability and accelerated accessibility. The company was founded by a technologist with extensive experience in building innovative products and is supported by a team with decades of experience in higher education, accessibility, and custom learning design.

PREP - The Beginning

A few early explorations and in-depth discussions with industry leaders and accessibility experts helped the Continual Engine team understand the gaps in online accessibility for documents and images. Experts reported that most accessibility tools did not alleviate the challenge but instead they experienced complicated workflow of document accessibility, and lack of efficient digitization tools which affected business continuity.
These pivotal initial conversations provided valuable insights and the Continual Engine team recognized the need for a comprehensive solution that was able to address multiple document formats, structures, and varied user needs.
With an aim to close these apparent gaps by collaborating closely with stakeholders at multiple levels across industries, the team gained a deeper understanding of the challenges they faced in making inaccessible documents available for users of assistive devices. The goal was to ensure that the document structure, reading order, or format of each remediated document was preserved and readable through screen readers.
Recognizing a revolutionary opportunity, the Continual Engine team decided to design and develop an efficient product to counter the challenges of document accessibility and digitization. The genesis of PREP followed several brainstorming sessions, guided by experienced accessibility professionals, and intense teamwork.
