Signapse AI

What is Signapse AI?
Signapse translates videos, live events, signage, and announcements into British Sign Language (BSL) and American Sign Language (ASL) using generative AI reviewed by Deaf translators. Its three products cover post-production video (SignStudio), real-time live translation (SignStream API), and website embedding, serving transport operators, broadcasters, and enterprises that need sign language at scale.
Unlike generic captioning tools that add text overlays, Signapse generates photo-realistic sign language video from a large dataset of qualified signer footage blended by AI. SignStudio handles uploaded videos, documents, and YouTube URLs with brand customisation, while SignStream turns short English phrases into live BSL or ASL video in about 15 seconds for screens, broadcasts, and digital signage.
Transport networks use Signapse for train announcements (over 5,000 BSL announcements generated daily across the UK). Media teams batch-translate hours of content through SignStudio. Developers embed the SignStream API into apps, chatbots, and venue displays for real-time accessibility.
Vidby

What is Vidby?
Vidby translates, dubs, and subtitles videos for teams that need to reach viewers in other languages without hiring a full localization studio. Upload a file or paste a link, pick one of four quality tiers from fully automated AI dubbing to human actor voiceover, and get a localized video in minutes instead of weeks.
Where most dubbing vendors quote opaque per-minute rates, Vidby publishes subscription plans with included credits and a checkout calculator for one-off orders. The platform covers 150+ languages and dialects, offers kid, teen, and elderly AI voices, and includes lip sync, voice cloning, and burnt-in subtitle options on paid tiers.
YouTube lists Vidby as a recommended vendor for multi-language audio tracks. Corporate customers include media brands registered with Disney and Warner Bros. supplier programs. A free tier exists with watermark exports, while Basic starts at $9.95 per month with 100 credits.
