Lazy Scholar automatically searches for a freely available full text the instant you open a scientific paper. In use, it finds one 36-41% of the time*. NEW: Lazy Scholar can deep link with your institution to find full texts even when you're off campus. In addition, it attempts to extract helpful information about the paper if relevant such as quick links to the population, intervention, outcomes, measurements, funding statement, outline, references, abbreviations, and supplemental documents. Further, it checks for comments on the paper in PubPeer, provides various citation metrics on the paper and journal, and one-click citation styles, including a preformed powerpoint style.

Features in further detail:

-Infobar automatically appears when a paper is opened & tells you if a free full text is available, and provides various metrics & comments, along with fast citations.
-This can be turned off and you can click the browser button for these.
-Type "LS" in the address bar and quickly query Google Scholar, PubMed, or Web of Science.

What has inspired us?

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
