Store description excerpt
Rex is a study companion that teaches out loud. Ask a question and hear it explained on a board you can draw on, pull apart, and keep. Most study apps hand you more text to read. Rex shows you the thing itself: a heart mid-beat, a cell you can fly into, a physics problem you can grab and change while it runs. ASK, AND ACTUALLY UNDERSTAND Type or speak a question and get a clear explanation built onto the board in front of you, not buried in a chat log. Ask about what is already on your board and Rex can see it. ONE BOARD FOR THE WHOLE CLASS Notes, PDFs, drawings, timers, recordings, graphs, checklists and web research sit side by side on one canvas. Stop switching between five apps to study one subject. 3D SCENES AND LIVE CHARTS Explore over 70 interactive charts and 20 explorable 3D scenes across biology, physics, chemistry, earth science and computing. Zoom from a whole body down to a single molecule. Change the inputs and watch what happens. RECORD THE LECTURE, GET THE NOTES Rex transcribes while you record, so your notes write themselves. LISTEN INSTEAD OF READING Any note, PDF or scanned page can be read aloud in a natural voice, each sentence highlighted as it is spoken. Photographed pages work too. SPEAK A NEW LANGUAGE Practise in twenty languages by walking through real scenes and talking with characters who answer back. STUDY TOGETHER Share a board and work on it live with classmates. FREE TO START The whiteboard and the core study tools are free. SUBSCRIPTIONS Pro, $11.99 per month. Pro Annual, $99.99 per year, which is about 36 percent less than paying monthly.
