Frequently Asked Questions
- What's the most accurate AI subtitle generator?
- Tools using OpenAI's Whisper model (like Subtape) consistently rank highest for accuracy, especially for English. Descript's proprietary model is also very accurate. For non-English languages, Happy Scribe's human review option ensures the highest accuracy.
- Can I generate subtitles for free?
- Yes. Subtape offers 5 free AI subtitle generations per month. Kapwing and VEED.io also offer free subtitle generation but add watermarks to exports. Descript offers 1 hour of free transcription.
- What's the best format for subtitles — SRT or VTT?
- SRT is the most widely supported format and works with YouTube, Vimeo, and most video players. VTT supports more styling options and is used for HTML5 video. Most tools in this list export both.
- Can AI subtitles handle multiple speakers?
- Descript has the best speaker detection, labeling different speakers in the transcript. Other tools generate subtitles without speaker labels, though you can manually add them.
- Should I burn subtitles into the video or use an SRT file?
- It depends. Burned-in subtitles are visible everywhere (social media, messaging apps) but can't be turned off. SRT files let viewers toggle captions and are better for YouTube, accessibility, and SEO. Subtape lets you do both.
