• Predatory journal warnings (Beall's List)
• Citejacked journal alerts (paper mill detection)
RESEARCH INTEGRITY
• Retraction alerts - know immediately if a paper was retracted
• Expression of Concern notices
• Published corrections and errata
• Preregistration detection
• PubPeer comments - post-publication peer review

- It is great, but it needs some improvement. It takes forever for it to show infos like an impact factor on some journals such as "Advances in Colloid and Interface Science". If there is no info in the database, can it just admit it and mark it as unknown instead of keep searching? Plus, maybe I was wrong but I think you should be able to find a complete list in excel file for impact factor somewhere on the internet.

- Familees
- Not sure how I ever did any assignments without it. Originally looking for Refworks this beats it hands down. the ability to find full text/PDF and associated papers are great. Don't forget it will cite the paper in which ever format you need, including the particular university style. Ie "Coventry-Harvard" or "DeMonfort-MLA". There's also the "related/suggested papers" tab which will find as it says on the tin related papers usually with full text and referencing. Could not recommend it enough.

- Runs automatically, even when it's configured not to. Since I can't turn it off without disabling the extension, I wonder what data it's sending out about my browsing habits!

- It's quite useful. But it keeps popping up automatically even when the options had all been set to "no". This is really annoying and unusable.

- Thank you! I just wish Google would allow an option to put a small "open access" symbol next to a search result to indicate which articles are free to read.

- Great extension. Quite useful. Though the new predatory journal detection is kinda glitchy and shows up at random pages that are not journals at all. For instance if you try to view a page's source code, you'll see it pop up.

- It hardly ever found PDF documents for scholarly articles. I like the idea (that's why I gave it 3 stars), but in its current form, I did not find it useful at all. So I just decided to use extensions for reference manager systems (Mendeley, Zotero, etc.)

- An excellent extension. I prefer to think of myself as efficient rather than lazy though!

- Crystal “Qrystal” McKenzie
- This might be my first time reviewing a Chrome Extension... but this extension has transformed my research life, and it is totally worth five stars. And even though I try not to identify with "lazy", I definitely dislike having to jump through hoops when trying to glance through a few dozen papers to see if they touch on an idea I need to reference. Now... it's like... I'm SURFING between articles!

- An interesting application but a bit too intrusive (especially in PDF download). Also it is too slow
