Frequently asked questions
- Why use an AI subtitle generator?
The value is speed first, then polish where it matters.
Skip manual transcription: AI gets you to a first draft fast, so you are not typing out dialogue or timing captions from scratch.
Edit before you publish: you still control the final result. Review wording, timing, and line breaks before exporting your captions.
Use one lightweight workflow: generate subtitles, make fixes, and export from the browser without opening a full editing suite for a simple caption job.
AutoSubtitles is built for people who want a fast AI subtitle generator, not a bloated editor. You get accurate subtitle drafts quickly, real editing control when the AI needs cleanup, and exports that are good enough to publish or hand off downstream.
- Is this AI subtitle generator really free?
Yes. AutoSubtitles lets you generate AI subtitles for free in your browser. The free plan includes the full editor, every caption style and animation, and exports up to 720p for videos up to 10 minutes, with a small watermark and no signup required.
- How does the AI subtitle generator work?
Upload a video, let the AI transcribe the audio, review the subtitle text, then export either a burned-in video or subtitle file. AutoSubtitles runs in the browser, with only the audio sent for transcription.
- Do I need an account to generate AI subtitles?
No. AutoSubtitles works instantly with no signup, login, or account. Open the site, upload your video, and generate subtitles right away.
- Can I edit the subtitles after AI generates them?
Yes. You can correct words, adjust timings, split or merge lines, and style the captions before exporting your final video or subtitle file.
- What languages does the AI subtitle generator support?
AutoSubtitles supports 20+ languages with automatic language detection, including English, Spanish, French, German, Portuguese, Japanese, and more.
- Does my video stay private?
Your video is processed locally in your browser. Only the audio needed for AI transcription is sent for processing, and it is deleted immediately after.
