It's not what's in your pocket.
It's what's in your head — and Rex is here to help you fill it.
On iPhone & iPad now · Android coming soon · Always free to learn.
Rex wasn't built for the student who already has everything figured out. It was built for the student who got the bad grade. Who was told they weren't smart enough. Who picked the smaller school. Who's betting on themselves anyway.
Knowledge is the one thing nobody can take from you. You can't buy a crown — you earn it. Rex is here to help you earn yours.
And because we believe anyone should have access to great learning tools, Rex starts free. No paywalls on the basics. You show up. Rex shows up for you.
Everything you need
Your tutor, smart boards, voice mode, charts, whiteboards — built to help you actually understand, not just memorize.
Ask anything. Get real explanations, step-by-step walkthroughs, and study help across every subject — math, science, history, coding, and more.
Organize your notes, charts, and ideas on infinite digital canvases. Everything syncs so your study session is always waiting for you.
Study hands-free. Talk to Rex out loud — it listens, responds, and reads answers back with natural on-device speech.
Visual learner? Rex includes subject-specific interactive widgets — math graphs, science diagrams, and more that you actually engage with.
Draw it out. Free-form whiteboard built for thinking through problems visually — because sometimes you just need to work it out by hand.
Type or dictate notes and let Rex help you expand, summarize, or quiz yourself on what you just wrote. Your notebook, but smarter.
