μὴ φρόντιζε (don't worry): we have a reason! I used to teach Greek and Latin, and our very first product, Epigrammar, took its inspiration from Classical antiquity: the English word “epigram” comes from “ἐπί” (epi) and “γράφειν” (graphein) meaning “to write upon” (historically, epigrams were written upon household items such as broken pottery or sea shells). With Epigrammar, we wanted to digitize the ancient way of writing upon things, so instructors could give their best feedback once and repurpose it everywhere. Now, with Epihub, we're still focused on helping instructors (fun fact: Aristotle was a tutor to Alexander the Great), but at the same time, we also want to help people build hubs for knowledge (ergo, Epi-hub).
