Auto-Generate Subtitles for Any Video
Upload a video and ScreenApp transcribes the audio automatically, then lines the text up with timestamps so it comes out as a subtitle file. There’s no manual typing and no timing to set by hand: the AI listens to the video and does both at once.
You get the file, not a captioned video. Add the SRT or VTT to your upload on YouTube, drop it into your editor, or use it on any platform that reads subtitle files.
What you get:
- A transcript with timestamps, in 100+ languages
- Export as PDF, DOCX, TXT, SRT and VTT
- transcript and caption translation, for a subtitle track in a second language
- Speaker labels when more than one person talks
- Free plan: 2 transcriptions of recordings up to 45 minutes each
How to Auto-Generate Subtitles
- Upload a video or paste a link: drag in an MP4, MOV, AVI, WebM or similar file, or paste a video URL.
- Let the AI transcribe it: ScreenApp processes the audio track and times each line to the moment it’s spoken, with no manual entry.
- Download the subtitle file: export as SRT or VTT and add it to your video on YouTube, in your editor, or on the platform you publish to.
Accuracy depends on the audio. Clear, single-speaker narration transcribes best; overlapping speech or heavy background noise leaves more to review and fix. See how we measure accuracy.

Who Uses an Auto Subtitle Generator
Content creators upload a video once and get a subtitle file ready to attach on YouTube or another platform that reads SRT and VTT natively, without typing a single caption.
Educators turn a recorded lecture or webinar into a transcript automatically, then export the file so students who need to read along or use a screen reader can follow it.
Businesses run product demos and training videos through the generator so viewers with the sound off still get the message, then attach the file when they publish.
Podcasters publishing video versions get subtitles generated automatically from the recording instead of typing captions by hand for each episode.
International teams transcribe a video and use caption translation to produce a subtitle track for a different market without re-recording anything.
Filmmakers generate a first-pass subtitle file for dialogue in a short film or documentary, then review it for accuracy before publishing.
