AlterAI

What is AlterAI?
AlterAI is a Chrome extension from Secrin Labs that turns informal Hindi and English text into formal English with one click. It is built for anyone who reads or writes Hindi online and wants polished English output without leaving the page.
Most Chrome translators lean on Google Translate for dozens of language pairs. AlterAI does the opposite: it only handles Hindi and informal English input, and it rewrites the result into formal English rather than a literal word-for-word translation. That narrow scope is the whole point if you need business-ready phrasing from casual Hindi or Hinglish you found on a webpage.
The extension sits in your browser toolbar. Select text on any webpage, trigger translation, and get formal English back. It runs on Chrome and other Chromium browsers that support extensions.
It fits professionals, students, and bilingual readers who run into Hindi content during everyday browsing and need a fast path to clear, formal English.
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.
