i like it
Its Great tool, but I need use it Out of web page also, however it is very Useful.
挺好用
it is ok
good
In my second year of uni and I have to say this is going to be so helpful after I graduate and I wont have access to the uni's library anymore! There have been the odd few papers it's not been able to locate for me but the vast majority have been there! I'm really happy with it. Thank you :)
Its really very superb extension for researchers and especially from third word countries whose could not afford costly papers. The one more thing about it that when you are searching a specific field it gives you relevant papers year vise and citation vise. The highly cited papers come first and in choronological order. Hats off to this app and developers. Thanks and need more from this if it can introduce a notebook feature with highlighter and notes features so that we can jot down our ideas on the same place.
v fas and useful timful
Some recent articles can't be found (yet), however this remains an unavoidable addon for any research enthusiast out there. Works perfectly on anything that's been published for a longer period of time. Long live the crow
Worked like a dream first time! Took me about 20 seconds from finding the paper I wanted to read, to actually having the full text under my nose. Big thanks for this extension! 🙏🏼
