Autoplay Youtube Thumbnail Previews Thingy is a Chrome add-on developed by dai. This free program falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The main purpose of this add-on is to animate all the Youtube preview thumbnails at the same time. Instead of having to hover your mouse over a single thumbnail to play a preview, this add-on allows all the video thumbnails on the page to play simultaneously, without requiring any mouse hovering.

Autoplay Youtube Thumbnail Previews Thingy currently works for search results, Youtube channels, and related videos on the video page. To use the add-on, simply load the extension, turn it on, and reload the Youtube page.

It is worth noting that the add-on does not work on the homepage and does not log or track any user information. If the add-on stops working, users can reach out to the developer for assistance.
