Ultra Audio Description Maker

Adds audio description to any video: the narration that tells blind and low-vision viewers what happens on screen. AI analyses the video and writes short descriptions, the user reviews and edits them, and a natural voice speaks each one at the exact moment the action happens, in the pauses of the soundtrack, the way streaming services do it. Professional audio description is expensive and rare, so most online video has none; this tool lets any creator, teacher or organisation add it themselves.

Available as a Windows desktop app (released), a browser extension that describes web videos live while you watch, and an Android app (in development). Opens local files or web links, downloads FFmpeg automatically, reports detailed progress, and uses the user's own Gemini key, so there is no subscription. English and Serbian interface.
