The script it writes
From the example above. Where the narration leaves a gap, the description goes in the gap. Where it doesn’t, the video pauses at the end of a sentence, the description plays, and the video carries on.
How it works
Upload your video
MP4, MOV or WebM, or a Google Drive or Dropbox link.
AI reads the picture
Speech is transcribed, pauses are found, and on-screen text, charts, people and actions are described in short, objective lines.
Voiced and fitted
A natural voice reads each line, in a gap or with a brief pause. Each line is checked against its frames before export.

ADA Title II
U.S. state and local governments, including public colleges, must meet WCAG 2.1 AA: by April 26, 2027 for entities serving 50,000 or more people, April 26, 2028 for smaller ones. Timeline
European Accessibility Act
Enforced since June 28, 2025 for many consumer-facing products and services sold in the EU, with EN 301 549, aligned with WCAG 2.1 AA, as the reference standard.
Your clients ask for it
Course publishers, training vendors and agencies that sell to public institutions are asked to prove their video is accessible before a contract is signed.
Questions
What is audio description?
Audio description is narration that tells blind and low-vision viewers what is happening on screen: on-screen text, charts, actions and scene changes that the soundtrack does not explain.
Does WCAG require audio description?
Yes. WCAG 2.1 success criterion 1.2.5 (Level AA) requires audio description for prerecorded video with synchronized media. Level A (1.2.3) allows audio description or a full text alternative. Most laws that point to WCAG 2.1 AA, including the ADA Title II rule and the EN 301 549 standard used under the European Accessibility Act, therefore expect audio description.
What do I get back, and how?
Everything is delivered in your browser: download an audio-described MP4, a full-length audio description track, WebVTT and SRT files, the script and a compliance note, one by one or as a single ZIP. Direct publishing to YouTube and Vimeo is coming soon.
Standard or extended description?
Standard description fits inside natural pauses. When the narration is continuous, like most lectures, we produce extended description, which briefly pauses the video. Extended description is WCAG 1.2.7 (Level AAA) and is the only way to describe dense videos without talking over the speaker.
Is AI description accurate enough?
The pipeline checks every description against the frames it describes, prioritizes on-screen text and numbers, and never guesses names it cannot read. AI can still misread a scene, so every plan includes a script editor: change any line and the audio, track and VTT are rebuilt automatically in seconds.
How long does it take?
Fully automated, around the clock. A 10-minute video is usually ready in a few minutes; large batches run in parallel.
