An offline auto caption app for Windows, Mac soon

Short answer: Offline Captions is a desktop app that makes animated, word-by-word captions entirely on your computer. Drop in a video, fix the few words it flags in yellow, export an MP4 with the captions burned in plus an SRT. No uploads, no credits, no subscription: $39 once ($29 founding). Try it first in the free web version (clips up to 5 minutes).

What "offline" means here

Transcribed on your computer

English runs on NVIDIA Parakeet-TDT, a Hinglish mode handles Hindi-English speech, and Whisper covers other languages. The model downloads once.

Rendered on your computer

Captions are burned into the video with ffmpeg at the source resolution, up to 4K. Nothing is queued on a server.

No meter

No minutes, credits or video caps. Caption a whole folder in one batch.

How it works

Drop in a video or a folder

MP4 or MOV from your phone, camera or editor. Pick English, Hinglish or another language.

Check the yellow words

Words the engine is unsure of are highlighted, so you review a handful instead of the whole transcript. Fixes go into a personal dictionary.

Pick a style and export

Bold, Clean, Punch or Reveal. You get the captioned MP4 and an SRT for YouTube, CapCut, Premiere or DaVinci.

How accurate is it?

On our own 28-clip English benchmark, the Parakeet engine scored a 7.6% word error rate, against 9.6% for Whisper-small on the same clips. That puts it in the same range as the cloud tools, without the upload. Method, results and limits.

Compared with other offline caption apps

Most offline tools make plain subtitle files; fewer burn in animated, short-form styles. See the honest roundup of offline caption apps, including free ones.

FAQ

Does it really work without internet?

Yes. Offline Captions downloads its speech model once, then transcribes and renders on your computer with no connection. Only licence activation needs the internet.

Is my video uploaded anywhere?

No. Video and audio stay on your machine. There is no cloud transcription step to opt out of.

What is the best offline auto caption app?

For animated word-by-word captions on Reels, Shorts and TikTok, Offline Captions ($39 once) is built for exactly that. For plain subtitle files and translation, free tools like Overcaption are strong. Our roundup compares seven.

Windows 10/11 today. The Apple Silicon Mac version is coming soon; the free web version already works on a Mac.
