Frequently Asked Questions – Video Subtitle Generator 2026

Is this video subtitle generator really free?

Yes, 100% free and will remain free. awaaitools.com provides unlimited usage without sign‑up or hidden costs. All processing happens in your browser – we don’t charge or show ads.

How accurate is the auto subtitle generation?

It uses your browser's built‑in Web Speech API (speech recognition). Accuracy depends on audio quality, language, and accent. For best results, use clear speech and low background noise. You can manually adjust any subtitle timing.

Do you store my videos or subtitles?

Absolutely not. Everything stays on your device. We have no servers that receive your video. That’s why it’s called “client‑side”. Your privacy is our priority.

Can I generate subtitles in languages other than English?

Yes! Web Speech API auto‑detects or uses the browser's language setting. Most modern browsers support dozens of languages. The generated text will match the spoken language.

What subtitle formats can I export?

You can download .SRT (SubRip) and .VTT (WebVTT), both compatible with YouTube, Vimeo, and media players. Additionally you can export an MP4 with subtitles burned in (experimental client‑side burn).
