Speech to text
Every word timed, so captions land on the beat
The audio is transcribed with a timestamp for every word, and the language is detected automatically. Names and technical terms can still be misheard on noisy audio; fix them in the text editor and the clip re-renders with the corrected captions.
Caption styles
Three caption styles, switch any time
Bold word-by-word, karaoke highlights or calm and minimal. Pick one per clip and change your mind later: re-rendering with another style costs no credits. In every style the key words of a clip are picked out in an accent color. Per-platform templates come after the beta.
Turnaround
Drop a file, come back to captioned clips
Paste a YouTube link or upload up to one hour of footage. Transcription, clip selection and rendering run in the background, so you can leave the page and come back when the clips are ready.
Brand styling
Your fonts, your colors, your brand
Save a brand kit with your caption and highlight colors, one of five caption fonts and your logo, and apply it to a project. Or open a clip and customize its captions: font, text, highlight and outline colors, size, position, uppercase and emoji, with a live preview, for that clip or every clip of the project. Uploading your own font file comes after the beta.
Text-based editing
Edit text, not timelines
Open a clip in the text editor to fix a misheard word or trim the clip by choosing its first and last word. Saving re-renders the clip, and the burned-in captions and the SRT and VTT files show the fix. Deleting a sentence from the middle comes after the beta.
Clip, caption, post, measure. One workspace for all of it.
Each feature page shows one tool. They all run on the same project, so a clip made here is ready for captions, scheduling and analytics without an export in between.
