Why YouTube captions are both accessibility and SEO.
YouTube's auto-generated captions are about 70 percent accurate, which fails on technical terms, proper nouns, and accented speech. Inaccurate captions hurt accessibility (deaf and hard-of-hearing viewers get garbled text) and SEO (YouTube reads the caption text for keyword ranking, so wrong words mean wrong rankings). Our AI generates captions at near-perfect accuracy by reading your video, scripts, and any reference docs, then formats them with timestamps in YouTube's expected SRT or VTT format. Multi-language tracks generate from the primary script. The captions get the search weight and the accessibility coverage in one pass.

Accurate captions plus timestamps in one export.
YouTube's auto-captions miss the words that matter most: technical terms, brand names, niche jargon. Inaccurate captions hurt accessibility and SEO. Our AI reads the video and (when provided) your script, then generates captions at near-perfect accuracy with timestamps in YouTube's expected format.

Creators in technical or jargon-heavy niches
Creators making content with technical terms, brand names, or specialized vocabulary that auto-captions consistently get wrong. Our AI handles the accuracy that the auto-caption layer fails on.

Caption questions
What creators ask about captions and SEO.
Does YouTube use captions for search ranking?
Yes. YouTube reads the caption text and weights it for video ranking, especially for specific phrases viewers might search.
What's the difference between captions and subtitles?
Captions transcribe everything (speech, sound effects, music cues) for deaf and hard-of-hearing viewers. Subtitles only translate speech.
Can our AI translate captions to other languages?
Yes. Ask for additional language tracks. Our AI translates your primary caption file to the languages you specify.
What format does YouTube accept?
SRT and VTT are both supported. Our AI exports both.
Will captions slow down my video upload?
No. Captions upload separately as a text file. The video upload happens first; captions get added after.
Should I use auto-captions or generate my own?
Generate your own for any video where accuracy matters. Auto-captions are fine for casual content but always need at least a quick review.
