Captions for people watching on mute
Most short videos are watched without sound. Word-level captions keep the viewer reading along instead of scrolling past.
Your talking-head video, bouncing highlight style
Upload a video and get subtitles timed to the exact word, in the style short-form accounts actually use. No typing, no dragging a caption around a timeline.
From the file on your desk to a subtitled video you can post.
Any video you already have: a talking head, a podcast clip, a voice-over. The language is detected on its own, so there is nothing to declare.
Not a block of text per sentence: a start and an end for each individual word, which is what makes subtitles land on the syllable instead of a second late.
Eleven ready-made styles, from clean broadcast captions to the bouncing highlighted look. Change anything you want in the editor, then render.
The details that separate real subtitles from auto-generated ones.
Every word carries its own start and end, so the highlight follows the voice exactly. Sentence-level timing is what makes most auto-subtitles feel out of sync.
Each preset sets the font, the outline, the highlight colour and the animation together. Pick one, and it already looks like the accounts you are competing with.
A second pass reads the transcript and marks the words that carry the meaning. Those get the accent colour and the pop, the filler words stay calm.
Turn on speaker detection and an interview comes back with each voice on its own colour, so a viewer knows who is talking without hearing it.
A name Whisper got wrong is corrected in one place and updated everywhere it appears, instead of being edited in nine separate captions.
9:16 for TikTok, Reels and Shorts, 16:9 for YouTube. The subtitles are placed for the format you chose, not squeezed into it afterwards.
Auto Subtitles is a free online tool that adds word-by-word subtitles to a video automatically. Upload a talking head, a podcast clip or a voice-over: Whisper detects the language and times every single word, the AI highlights the words that carry the meaning, and eleven ready-made styles give it the look of short-form captions. Speaker detection gives each voice its own colour.

Turn on speaker detection and each guest gets a colour, so a viewer knows who is speaking even without the audio.

Ads and demos often start muted in the feed. Clean broadcast captions carry the pitch until the viewer turns the sound on.

The language is detected on its own, so a video in Portuguese, Japanese or Polish is subtitled the same way as one in English.

Accurate, word-timed captions make every video readable for deaf and hard-of-hearing viewers, with nothing to type by hand.

Whisper handles around a hundred, and detects which one it is hearing on its own - you do not pick it beforehand. Accents and code-switching are handled well; very noisy audio is where any speech model starts to guess.
The transcription step takes files up to 25 MB, which is a few minutes of a normal clip. Longer than that, cut it into parts - and the editor lets you paste the pieces back into one timeline.
Yes, all of it: the words themselves, where the lines break, how many words show at once, the position, the colours, which words are emphasised. The generation is a starting point, not a locked result.
No. The subtitles are rendered into the video itself, which is what short-form platforms need - a separate subtitle file is ignored by TikTok, Reels and Shorts feeds.
Yes. Music-only passages are recognised as such and left without text rather than transcribed into nonsense, and the speech around them keeps its timing.
Creating and subtitling a video is free; only the final render consumes credits, and a free account gets renders to try it with. You see the cost before you start it.
