Leading AI for Sign Language Accessibility
BSL and ASL solutions designed by Deaf-led teams, built for digital platforms, education, communications, and transport
Make digital content
accessible and inclusive for all.
Signapse builds AI-powered tools that translate spoken or written English into British Sign Language (BSL) and American Sign Language (ASL), quickly, accurately, and with cultural respect.
Unlike subtitle-first solutions, we centre sign language as the first language for millions of Deaf users. Our products help you build access into your content, communications, and infrastructure.

Real customer experiences
Transport for All believes that every disabled person should be able to access information in a format that works for us. There’s been a fantastic rise in the number of organisations making information accessible to BSL users, but there are now long waits for translators to work on materials. Signapse’s system allowed us to plan with confidence. We knew the translation would be ready, and we could be certain our communications would be accessible to all

Real customer experiences
Working with SignStudio has been a dream. It wasn’t a “good” alternative, it was an ideal one. Not only was SignStudio able to modify their deliverables to our needs (a full screen translator video rather than an overlay) but their service teams were so open and willing to work with us every step of the way. We could not have achieved our goal of producing 14-16 hours of translated content at speed without this solution.

Why Subtitles Aren't Enough: The Case for Sign Language Access
Subtitles are useful but they’re not true access. For millions of Deaf people, British Sign Language (BSL) or American Sign Language (ASL) isn’t just a helpful feature. It’s their native language. That means relying on text-based solutions like subtitles or captions can leave them confused, disengaged, or completely excluded.
This whitepaper explains why and what you can do about it.
It’s clear, practical, and packed with real-world examples that bring the issue to life. We walk through the challenges Deaf people face when subtitles are treated as a one-size-fits-all solution, especially in live events, video content, education, and public announcements. We also explain why so many subtitling tools (like live auto-captions) fail to meet the mark.

While we are not currently able to support the translation of on-the-fly messages, this is a capability we are working towards.
We currently support the translation of English text into British Sign Language (BSL) or American Sign Language (ASL). We plan to support additional languages and sign languages in the future.
