Frequently asked questions
- Why does no watermark matter?
Free should still look usable when you hit export.
AutoSubtitles gives you a clean starting point: AI subtitle generation and simple watermark-free exports. Switch to the full editor for presets and animations, or go Pro for custom fonts, saved styles, and no watermark.
Good enough for publishing: free exports are simple, readable, and usable for real videos when you just need clear subtitles.
Useful basic control: you can still adjust font, size, color, background, outline, and shadow: enough for clean subtitles that fit your video.
Start clean, upgrade later: free is built for simple, readable subtitle exports. If you need richer styling and more polished visual treatment, upgrade when the project calls for it.
- Is AutoSubtitles really free with no watermark?
Yes. The simple editor lets you generate subtitles, style them, and export your video with no watermark: unlimited, free, no signup or credit card required.
- What’s the catch? How is it free?
The simple editor covers the essentials (AI subtitle generation, typography, color, background, outline, and shadow) and exports without a watermark at up to 480p. The full editor adds animations, word highlighting, 28 style presets, custom font uploads, and saved styles; it exports with a small watermark unless you upgrade.
- Do I need to create an account?
No. AutoSubtitles works instantly in your browser with no signup, no login, and no account. Just open the site and start adding subtitles.
- Is my video uploaded to a server?
No. Your video stays on your device and is processed locally in your browser. Only the audio track is sent for AI transcription and is deleted immediately after.
- What video formats are supported?
AutoSubtitles supports MP4, MOV, WebM, and most common video formats. It works with any aspect ratio: landscape, portrait, or square.
- Can I create auto captions without a watermark?
Yes. The simple editor exports auto captions and subtitles without a watermark, unlimited and free. If you want richer styling (animations, presets, custom fonts), the full editor adds those, and Pro removes its watermark.
