Readable

What is Readable?
Readable translates PDF files into Japanese while keeping the original layout intact, including tables, figures, and images. Built by NextLab Inc., it targets researchers reading academic papers and business teams working through manuals, reports, and contracts without rebuilding documents by hand.
The reader shows original and translated text side by side so you can scan a translation and jump back to the source line when something needs a closer look. Premium users can register custom dictionaries so product names, abbreviations, and field-specific terms translate the same way every time.
Readable runs in the browser and through a Chrome extension for quick file translation. Pro Standard focuses on English-to-Japanese PDFs, while Pro Premium adds 200+ source languages, larger file limits, and optional ChatGPT-based translation engines.
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.
