Welcome to Thumbsy

How Thumbsy fits together
- The extension lives on
youtube.com. It adds a save menu to every thumbnail, a one-click color palette tool, a Studio overlay for exporting styled thumbnail cards, and bulk-select tools for grabbing many thumbnails at once. - The webapp (this account's dashboard, at
thumbsy.io) is where everything you save ends up. Organize it into boards, search and filter, export cards, and — on Pro — access the Vault, run feed simulations, and collect feedback through Collab Reviews.
Both share one account. Sign in once in the extension and your saves sync straight to the dashboard.
