" I love Glasp! I use it every time I read online articles. Highlighting with Glasp enforces me to actually read rather than scan through an article. I retain so much more info and can easily revisit my previously read articles to recall details and notes I've made. "

" Glasp drastically reduces the time for note-taking for me. I needed a common platform to keep references and notes, where everyone could seamlessly collaborate. In any situation that requires collaboration, oftentimes, it acts as a references repository for our knowledge base. It allows me to keep my notes easily accessible to myself and across my teams. I’ve been using the tool religiously over the past 6 months and with Glasp, I’ve been able to keep my work more organized and productive. I use it every time I read anything online. Moreover, the Glasp community—even outside my inner team—allows me to explore what others are reading, helping me discover interesting new articles every day. Absolutely love discovering this new social network! "

" I've researched every highlighting tool from Liner and Hypothesis to Instapaper and Pocket, and Glasp is the best hands-down. First, it creates a whole category of its own with social highlighting. This is important because it helps learners get recognized for finding amazing highlights, and it helps them connect with others who are learning the same thing at the same time. Also, it has the best highlighting workflow. While reading an article, you can select text in order to highlight and annotate without having to go to a different page. Furthermore, all of your highlights for a specific article appear on a right sidebar as you're reading, and they're easy to copy and paste into another note-taking app. "

" As someone who has been following the GTD, Zettelkasten, PKM, Second Brain, zettelkasten ways of working, Glasp helped me shift from following to doing.  It acts as a forcing function, motivating me to think through what stood out, why it stood out, and to categorize it according to what I'd be interested in learning more about. Also, Glasp lets me see other's highlights, which feels like following a bread crumb trail to interesting content and insights I wouldn't have normally come across. Glasp helps me curate thoughtful, provocative information, that I can build into my writing practice. "

" Glasp makes it easy for me to remember what I read and watch on a daily basis. The app is always ready to let me highlight the important passages and create notes. Exporting the higlights is as easy as using a one-click button to paste it to my Obsidian vault. Glasp not only has these features but it also functions as a community where you can see what your friends are reading and highlighting, so everyone can learn from each other. It takes the concept of "learning in public" to the next level. Highly recommended for life-long learners. "
