About this extension
GrumpTools Assist puts a save button on every YouTube thumbnail so you can collect the ones that work, then study them side by side on your GrumpTools inspiration board.
HOW IT WORKS
Hover any video on YouTube and click the GrumpTools button. That's it. It appears on the home feed, search results, channel pages, the watch-page sidebar and Shorts. Your board lives at grumptools.com/tool/thumbnail-inspo, so it's on every device you sign in from.
SAVE WITH A NOTE
Hover the button a moment longer and a small menu opens beside it. "Save with note" lets you jot down why a thumbnail caught your eye, the part you'll have forgotten by next week. Notes are yours to edit or delete later from the board.
