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.
Rask

What is Rask?
Rask translates and dubs video and audio into 130+ languages with cloned voices, lip sync, and subtitle workflows built for marketing clips, training modules, and long-form media. Upload a file or connect via API, and the platform handles transcription, translation, voice generation, and optional lip matching in one pipeline.
General translation suites spread across text, documents, and live chat. Rask narrows on A/V localization with multi-speaker detection, a translation dictionary for brand terms, voice presets, and SOC 2 Type II certification for enterprise buyers who need audit trails. Free browser tools cover subtitles, dubbing, and transcription without opening the full editor.
The product targets L&D teams, marketers, podcasters, and film distributors who publish the same footage in multiple languages. Plans scale by included minutes from a 3-minute free trial through Creator, Creator Pro, and Business tiers, with custom Enterprise contracts for high-volume API users.
