Automatic or hands-on
Start from generated text, then make precise corrections instead of retyping the entire video.
Add subtitles to a video in one straight line.
Bring the clip. Automatic transcription, caption editing, styling, and export stay together from the first upload to the finished file.

How it works
- 01
Add the video
Choose a supported video file or drop it directly onto the uploader.
- 02
Generate subtitles
The spoken audio becomes timed caption text automatically.
- 03
Edit and position
Correct the wording, choose a style, and place the captions where they stay readable.
- 04
Download
Export the video with subtitles burned in or download a separate caption track.
Built for the correction after generation.
Designed for silent viewing
High-contrast presets and active-word emphasis help short clips stay readable without audio.
One source, several destinations
Use a captioned MP4 for social feeds or take an SRT or VTT file to a platform player.
Nothing to install
The whole path runs in the browser. There is no desktop editor to download, no project file to manage, and no render queue on your own machine.
A deletion schedule you can read first
Uploads go from your browser to private storage. Guest projects are removed after a day, Free projects after 7 days and Starter projects after 90.
Keyboard as well as pointer
Caption position and size are adjustable from the keyboard, not only by dragging, so placement is not a pointer-only feature.
Burned in, or a separate subtitle file?
Both come out of the same transcript, and the right one depends entirely on where the video is going. This is the decision most people get wrong first.
Burn them in for feeds
Instagram, TikTok and Shorts autoplay muted and give the viewer no way to switch subtitles on. If the words are not in the picture, most of the audience never sees them.
Use a file where the player supports it
YouTube, Vimeo and most course platforms draw their own subtitle track from an SRT or VTT. That keeps the text selectable, translatable and searchable.
Burned-in captions cannot be turned off
That is the point on social, and a drawback elsewhere. A viewer who wants them gone, or wants another language, has no route to it.
You do not have to choose once
The same project exports both. Take the MP4 for the feed and the SRT for the platform upload without transcribing the video twice.

When this is not the right route.
Some subtitling jobs want a different kind of tool. These are the ones.
You already have a finished SRT
If the text and timing exist and you only need them attached, this will re-transcribe the audio rather than import your file. The free tools can convert and retime an existing subtitle file instead.
You need translated subtitles
Captions are generated in the language that is spoken. Translation into a second language is not part of this path.
Your captions must be in CJK or Thai
The speech transcribes, but no bundled font can draw those characters, so burning them in is refused rather than returned as empty boxes. SRT and VTT keep the text intact.
Questions before upload
How do I add subtitles to a video online?+
Upload the video, generate its transcript, review the timed captions, choose a style, and export the finished result.
Can I add captions to a video for free?+
Yes. Free includes 3 distinct video projects each month with watermark-free 1080P downloads; revising and downloading the same project again uses the same slot. Every style can be previewed, and Podcast Lower Third and Documentary can be exported on Free. Subtitle files are not counted.
Should I burn the subtitles in or use a separate file?+
Burn them in for muted autoplay feeds like Instagram, TikTok and Shorts. Use an SRT or VTT where the player draws its own track, such as YouTube or a course platform.
How long does it take?+
There is no fixed time. It depends on the video's length, your upload speed and how many renders are queued. The transcript is often ready to review before the whole video has finished uploading, because captions are made from the audio first.
Can I move the subtitles on the video?+
Yes. Caption placement and sizing can be adjusted against the video in the editor.
Can I download subtitles without burning them into the video?+
Yes. Download SRT, VTT, or TXT when you need a separate subtitle track. Those downloads do not use a monthly video project slot, and you still sign in to download them.
Do I need to install anything?+
No. Upload, transcription, editing, styling, and export all run in the browser.
What happens to my video after I download it?+
Free projects and their source files are deleted after 7 days, Starter after 90, and guest uploads after one day.
