Built for the student
who was counted out.

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 whole study life, in one app.

Your tutor, smart boards, voice mode, charts, whiteboards — built to help you actually understand, not just memorize.

Rex Tutor

Ask anything. Get real explanations, step-by-step walkthroughs, and study help across every subject — math, science, history, coding, and more.

Smart Study Boards

Organize your notes, charts, and ideas on infinite digital canvases. Everything syncs so your study session is always waiting for you.

Voice Mode

Study hands-free. Talk to Rex out loud — it listens, responds, and reads answers back with natural on-device speech.

Interactive Charts

Visual learner? Rex includes subject-specific interactive widgets — math graphs, science diagrams, and more that you actually engage with.

Whiteboard Tools

Draw it out. Free-form whiteboard built for thinking through problems visually — because sometimes you just need to work it out by hand.

Smart Notes

Type or dictate notes and let Rex help you expand, summarize, or quiz yourself on what you just wrote. Your notebook, but smarter.

Plans

Start free. Grow when you're ready.

No pressure. Rex starts free — always. Upgrade when you want more.
