Picking the best subtitle generator for your workflow
Ask yourself these 5 things:
- Are you creating YouTube videos, Reels, TikToks, or podcasts?
- Do you need auto captions in different languages?
- Will you export subtitle files like SRT, VTT, or burn-in on the video file?
- Do you care about animations, fonts, and templates?
- What’s the function—speed or perfection?
