slAItor

What is slAItor?
slAItor is an online translation assistant built around large language models from the GPT family, combined with standard machine translation pipelines. Instead of returning a single translated string, it is designed for people who want more context around a translation: explanations, alternatives, style adjustments, and error checking.
The product targets language learners, translators, and professionals who need more than a quick paste-and-go result. Benjamin Marie, who holds a Ph.D. in machine translation and has spent more than a decade in MT research, built slAItor to explore what becomes possible when GPT-style models sit at the center of a translation workflow.
slAItor supports 28 language pairs across Chinese, English, French, German, Italian, Japanese, Portuguese, and Spanish. The site is upfront that raw translation quality can trail established systems in some cases, but positions itself on price and on features like step-by-step explanations, paraphrasing, and a checker mode that reviews your own drafts.
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.
