Why use this one

Your video stays private

Nothing is uploaded — perfect for unreleased or client footage.

Readable by default

Lines are split to broadcast length (2 × 42 characters) so captions don't flood the screen.

Edit in place

Fix names and typos right in the list and see them on the video instantly.

English subtitles from any language

Translate speech in 90+ languages straight into English captions.

Questions

Is this subtitle generator really free?+

Yes — no sign-up, no watermark, no length limit. Subtitles are generated on your own device, so there's nothing for us to charge for.

Is my video uploaded?+

No. The video stays on your computer. Your browser extracts the audio and runs the Whisper speech model locally. Only the model itself is downloaded, once.

How do I add the subtitles to YouTube?+

Download the .srt file, open YouTube Studio → Subtitles → your video → Add language → Upload file → “With timing”, and pick the .srt.

Can I use the subtitles in Premiere, DaVinci Resolve, CapCut or Final Cut?+

Yes. All of them import .srt files. VLC and most video players will also load an .srt automatically if it has the same name as the video.

Can I make English subtitles for a video in another language?+

Yes. Open the options and set Subtitle language to “English (translate)”. The speech is translated to English as the subtitles are generated.

Can I fix mistakes before exporting?+

Yes. When it finishes, click any subtitle line to edit it. The video preview and the SRT/VTT exports update instantly.

Can it burn the subtitles into the video?+

Not yet — it exports subtitle files (SRT/VTT), which every editor and platform accepts and which viewers can turn on or off.
