Speech recognition that never leaves your computer
Most caption generators upload your video to a server, transcribe it there and charge by the minute. ClipLime does the opposite. It downloads Whisper, an open-source speech-recognition model, into your browser and runs it locally, on your graphics card through WebGPU when it's available, otherwise on your processor. Your audio is never transmitted, which matters for client work, unreleased content and anything personal.
The model is downloaded once and cached by your browser, so the next video starts transcribing almost immediately. Choose Fast for quick drafts, Balanced for most videos, or Accurate when there are accents, jargon or background noise.
Sentence subtitles or short-form captions
- Sentences, classic subtitles of up to two lines, split at natural pauses and punctuation. Best for YouTube, courses, interviews and anything watched with sound off on a big screen.
- Short-form, one to six words at a time, big and bold, the style that keeps people watching on TikTok, Instagram Reels and YouTube Shorts. Pair it with word-by-word highlighting.
Because ClipLime keeps the timing of every word, you can switch between the two at any point and the captions are regrouped instantly, no need to transcribe again.
Make them look right
Start from one of five looks, Clean, Pop, Boxed, Lime and Karaoke, then adjust size, position, font, weight, colors, outline, shadow and background. Highlight the word being spoken colors or boxes each word as it's said, which makes fast speech easier to follow.
The preview is drawn with the same code that burns the captions into the export, so what you see on screen is exactly what you'll get. For vertical videos, check that captions stay clear of the app's buttons with the safe zone checker.
Fix mistakes quickly
No speech recognition is perfect, especially with names and specialist terms. Click any line to jump the video to it and type the correction. Times can be typed directly, lines can be merged or deleted, and Find & replace fixes a misheard name everywhere at once.
Already have subtitles? Import an SRT or VTT file to restyle them and burn them in, no transcription needed. To convert or re-time subtitle files, use the subtitle fixer.
Burned-in captions or a subtitle file?
- Burn in (MP4) when the platform has no caption support or you want a specific look: Reels, TikTok, Shorts, ads, LinkedIn. The captions can't be switched off.
- SRT or VTT for YouTube, Vimeo, course platforms and editing software. Viewers can turn them on and off, and search engines can read them.
- Transcript for show notes, blog posts and quotes.
Tip: tighten the edit first with the silence remover, captions on a video without dead air read much better.
