## About the product

DeafSync is an AI accessibility platform, based in Cotonou, Benin, for deaf and hard-of-hearing people, hearing users, and organizations that need sign language translation, learning tools, and accessible media.

It operates through three products:
- **HandVoice**: real-time translation of text, audio, images, and video into sign language via an AI engine, output as a **3D avatar** or video, with real-time video-call translation and grammar/non-manual markers (like facial expressions) rather than word-for-word signing
- **Lambdy**: an e-learning platform offering adaptive courses in sign language and local language
- **Vocood**: a media dubbing tool that adds AI sign language dubbing, with 3D avatar technology, to existing video content

Developers can integrate translation into third-party apps via a **REST API**.

Available on **Web** (including a dedicated Deaf Translator web tool) and **Android** (HandVoice, on Google Play); a browser extension is stated on the site but no published listing was found.

It targets a **B2B2C** audience: individuals who communicate in sign language, plus companies, institutions, and media teams that want accessible communication and content.

Confirmed sign language coverage is **Beninese Sign Language (LSB)** and **American Sign Language (ASL)**; broader "Pan-African" coverage is stated as an ambition but not yet evidenced beyond these two. The company was selected for **MTN Benin's second Innovation Lab cohort** in 2026, and its site lists Mastercard Foundation, Tony Elumelu Foundation, Segal Family Foundation, and MDF as partners — though only the MTN relationship is independently confirmed in press coverage.
