Auto-Generated Captions for Video, Without a Subscription

Burned-in captions increase watch time on nearly every short-form platform — most viewers watch with sound off, especially on their commute or in public. The problem is that most captioning tools are either a paid subscription, a slow manual process, or both.

Speech-to-text has gotten good enough to run locally. Automatic speech recognition models that once required a server can now run inside a browser tab, producing timestamped captions from your video's audio track without uploading the file anywhere. It's not perfect — names, jargon, and heavy accents still need a manual pass — but for a first draft of captions it saves the bulk of the time.

Always proofread before publishing. Auto-captions will occasionally mishear a word in a way that changes the meaning of a sentence, which is worse than no captions at all. Budget two or three minutes to scan the output before you burn it into the video.

Timing matters as much as accuracy. Captions that lag behind the speech by even half a second read as sloppy. Tools that give you per-line timestamps let you nudge individual lines instead of re-generating the whole track.

One-time model download, then offline. Like other in-browser AI tools, expect a one-time download (often around 40MB) the first time you use auto-captions, after which the feature works without an internet connection.

If you're editing video anyway, Creator Command Center generates timestamped captions in the same Studio tab where you trim, resize and add music — no separate app, no upload.
