Editors’ Notes

No matter how much we use it, this app still feels like magic. Getting the answer to “Who built the Sphinx?” or “How does photosynthesis work?” is as easy as snapping a photo of the question, then watching Socratic’s mighty AI dig up helpful explanations and videos from a bunch of online sources. It’s quick, free, and awesome.

Socratic has your back!

As an upperclassman in high school: take my word for this - this app is amazing! As an AP/honors students I sure know what it’s like to not do assignments (due to tiredness, laziness, or legitimate reasons) or copy from friends the period before the assignment is due. I also know what it’s like to be an active user of Quizlet whenever I need to look up some test or quiz answers for reviews/studying or for straight up cheating (lol). But what we all know is that searching up each individual question on google and then having to go through several Quizlets to find the correct answers for each and every one can be quite time consuming and tedious. However, with this wonderful app it finds all the Quizlets for you in an instant by just taking a picture of the question! Even if Socratic can’t find an answer, it provides the user with at least a legitimate, scholarly definition of the subject matter of your question! In short, Socratic is a amazing and l totally recommend it to any type of student! Honestly, Socratic came through and helped me passed my finals this semester!



I love this app for so many reasons. I love that it gives you answers from different sources because certain sources give better explanations than other for certain problems. It’s really good at recognizing the text in a text book or my handwriting and I have really bad hand writing. It helps when I am doing a new type of problem and to make sure I am doing it right and if I don’t know how it can teach me how. It has helped me do so well in Algebra I. I just have one problem I recently got an iPhone X and now the app is all messed up. When you try to crop your problem it doesn’t do it right and it is all off center. It almost makes the app unusable. I understand the phone is still new and it takes time to update, but if you could do it as fast as possible it would mean a lot because I need this app. Thank you for making this amazing app it is far better than Photomath
