How it works / 90 seconds
Add a layer of attention.
Nothing more.
Caption Confidence improves a track you already have. It does not transcribe audio, scrape protected streams, or make medical claims.
-
01
Bring captions
Import a local VTT or SRT file, or read a caption track that an HTML5 video exposes.
-
02
Name your pairs
Add the exact words you tend to confuse. Matching words receive a high-contrast lichen mark.
-
03
Replay once
Press R from the page to return to the start of the current caption, with your chosen lead-in.
Honest signals

The extension also labels source-authored uncertainty and unusually tight or overlapping cue timing. Timing flags describe the caption file—not the speaker or your hearing.
