Spade: Draw on and Annotate the Web & PDFs

Amazing tutorial, best UI of an annotation extension I've seen so far. 10/10.

I tried at least 10 annotation tools n picked this one. ONLY flaw is that font size could be editable n smaller, similar to the font size on websites. Changing font doesnt really minimize the size. writing long comments not possible.

Don't know what's with the negative reviews. Absolutely love for studying!!

Requires a login, but no option to delete account. Extremely glitchy. Does not work at all. Don't waste your time, find another app.

I can't understand the instruction of this tools

Need to register in order to use. After that it's literally buggy and cant even properly draw on the pdf, there are places on it where it doesn't allow you to. Then after I tried saving my pdf it literally deleted most of my work on it...

AMAZING for taking notes while studying, recording thoughts on research for school

Great tool! Wish I found it earlier, other alternatives can't compare.

Great potential but as someone else noted tool bar only appears on Spade (and Google.com) websites.

Unfortunately, annotations and underlines break when changing devices - computers / tablets / phones
