Overview

Signapse is an AI sign language translation platform converting video content into British Sign Language (BSL) and American Sign Language (ASL) in real time. Generative AI blends a library of qualified sign-language video segments with natural transitions, producing translations that read as fluent signing rather than robotic, isolated signs.

Named products cover the full delivery chain: SignStream API for live translation, SignStudio Platform for post-production sign-language content, Transport Solutions for digital signage in transit environments, and a Website Plugin for embedding translated content directly on a site.

Signapse targets media and broadcast organizations, transportation networks, universities, government agencies, and corporate accessibility teams. Three pricing tiers are available, with a free trial of SignStream; specific rates aren’t published and require contacting the team.
