Captionfy is a free Youtube community captions platform with a subtitles/captions editor that you can use to create captions for any public Youtube video. You can then download the subtitles file, share the Captionfy video page with the captions (using the original Youtube video embed), and provide the Youtuber with a link to the video to download the captions and publish them on Youtube.

A recent update from YouTube allows YouTubers now to invite others to be "Subtitle Editors" for their channel. It is the closest they got to the old Community Captions (where anyone could caption the video, not only the "allowed" users). There are also free alternatives to Community Captions like Captionfy and Amara, but probably many YouTubers don't know about them. Source: about 2 years ago
If you want to contribute, but don't know where to get started, I recommend using Captionfy.io or amara.org. Source: about 2 years ago
