Video accessibility preflight
AI-assisted caption preparation for prerecorded MP4/WebM — human review recommended.
Video transcription requires temporary processing. Your video is uploaded to private temporary storage and sent to OpenAI for transcription. This application does not intentionally keep the uploaded video after processing. Generated transcript and captions remain in the current browser session unless you download them.
What this tool checks
- Timed caption cues and reading-speed heuristics
- Non-speech audio review prompts
- Platform video publishing checklist
What it does not do
- Certify ADA, WCAG, or legal compliance
- Burn captions into video or publish to social platforms
- Translate captions or live-stream captioning
Automated accessibility guidance is not legal advice or certification. Some criteria require human review in the native app.
