Scored by a Toolio reviewer after real useOur verdict
Platstack saves links, highlighted text with your own notes, and right-clicked images into a personal collection you can revisit and, if you choose, share publicly to a broader pool of saved knowledge. YouTube video-highlight capture is listed as coming soon rather than available today. Using it requires a separate Platstack account and mobile app to get the full experience, so this extension alone is really just the web-clipping half of a larger system.
