Hey y'all!
As y'all are well-aware, YouTube's auto-captions are inaccessible as they appear word by word, forcing us to fix our gaze on the ever-changing words in the caption bar instead of scanning the fully rendered sentence quickly and reverting our gaze to the actual content. I made a forever-free extension that rerenders them into customizable full phrase/sentence-style captions to show the full phrase
It works on Chrome, Brave, and Firefox. You can adjust font, size, position, lines, background, and much more. It's open source and doesn't collect data. I built it for myself at first, r/deaf (and many individuals I've been emailing back and forth with) gave tons of feedback and feature recommendations over the past months that helped shape the current version, including MUCH more context-aware features, manual customizability, and bug fixes. You can use it even on Youtube shorts. It has a few hundred users now!
Link to Demo, Chrome+Firefox Extensions, and Github. Alternatively just google "Ketuvia"!
The hardest part (after figuring out how to hook into youtube's caption API) was balancing readability guidelines from DCMP with full customization: showing full sentences when possible, splitting at natural clause boundaries (punctuation) when needed, and timing captions so they appear early enough to scan without lingering forever. I eventually figured out how to make it do the large amount of calculations/rendering almost instant, even on 5+ hour videos, so it should be lightweight and convenient to use.
I think the extension works pretty quick and intuitively now. I hope y'all find it useful too
