Find hypothesis because of running out of Weava storage space. Really impresses me not only the amazing introduction video and the feeling of reading webs by the whole world. Really nice extension! Updated: Well, I meet a issue after using for some while. How to enable it automatically when I open a web or a local pdf?
Every time i log into my account on a page i previously annotated, i get random highlights which i did not put there, nor do they make any sense. Anybody knows what is the problem/ solution. Thank you very much.
This is awesome. It would be cool if a feature were added that allowed users to upvote comments on an annotation(reddit style). This way could serve as an indicator of how valid/factual some users comments are if on a research paper for example
nada melhor pra estudantes! ferramenta útil demais! principalmente para leis !
It is easy to use and make my work more effciently
After a few semesters in school, and conducting research papers, I finally got fed up with not having the ability to highlight or take notes in real time on a web page. Insert Hypothesis. This honestly changed the way I research papers. Thank you so much for this amazing product
broken under this site: https://reactjs.org/docs/thinking-in-react.html annotations from different pages shown in one page
Excelente. Ajuda muito.
I would pay money for this and yet it's free! Amazingly clean and simple. Works great for all my note-taking, video/image posts, and research. Between Hypothesis and Diigo, my internet experience has changed the way I work and has inspired others. Please ensure this keeps going/growing! I have a lot of info invested in Hypothesis. Truly recommend for students and professionals alike! :)
While I know this extension for some time now, I always have missed a particular option. I am missing ome kind of website or source, which outlines where users annotate most websites... If something like this can be done, it would be great indeed.
