I like using the PDF viewer where you can have an avatar summarize stuff and look stuff up! It's not only great in educational contexts, but I've personally used it to sift through my Dungeons & Dragons handbooks to help come up with encounter ideas. Ha!

We built Holotutor because learning still feels more static than it should.
Most tools give you content. We wanted something that actually teaches you visually, interactively, and in real time.
