Never freeze from a cold call again
Never let a cold call catch you cold.
It’s week 3. The professor says your name. You don’t remember the holding. Most days that’s a 30-second freefall. With Rex, one ⌘K pulls the brief back up before you’ve cleared your throat.

How it works
Four layers, one continuous semester.
Each layer feeds the next. You only ever do the reading — Rex turns it into the schedule, the briefs, the notes, and the outline you’ll actually study from.
Layer 2
Briefs
Paste the text from your casebook. Rex builds briefs tailored to your professor's testing and cold-call style.
Layer 3
Notes
Slides on the left, your notes on the right — scroll-synced. A full rich-text editor: headings, bold, italics, highlights, and links.
Layer 4
Outline
Every brief, every note, folded in automatically. Exam-ready by November.
Your syllabus becomes a schedule.→Your reading becomes briefs.→Your class becomes notes.→Your semester becomes an outline.
30 seconds, end to end

This 30-second cut is just a glimpse — in everyday use Rex is far faster and more capable than a short animation can show.
