Origin to Zenith with Super AI
orZsai brings together smart notes, study plans, and AI problem solving, so you learn more efficiently.
Notes
Well organized.
And it moves.
From scattered materials to a clear knowledge tree to demos you can drag and spin — orZsai notes are built for hard subjects like science and engineering.
Outline · Mind map
One body of knowledge, two views.
Write in a structured outline, expanding level by level and dragging to reorganize. When you want the big picture, switch to a mind map in one click and see the whole subject laid out. Same content — nothing to keep in sync.
Smart Import
Old materials, new notes, one click.
Just drag in PDF lecture notes or screenshots. In the mobile app, you can also snap the blackboard or record a class and hand it to AI. AI recognizes chapters and key points and files them into your outline automatically.
Smart Import
Instant importAdd a file and click “Start import”
Processed in the background; notes are created when done
Interactive demos
Abstract concepts,
made visible and hands-on.
Geometry, function graphs, and physics models live right inside your blocks. Drag a parameter and watch it change. One figure per block, right in your notes.
Widget
3D physics models sit in a block like an image — rotate and drag them.
JSXGraph
Drag the slider and the curve follows.
Study plan
Learn it, then forget it?
Review right before you would.
Spaced repetition schedules when to revisit each topic. New material and reviews are planned day by day, so you can see your workload ahead of time. Mastery is tracked live, so you always know what to practice today.
Forgetting curve
Scheduling follows the forgetting curve, bringing each topic back just before you'd forget it.
New / Review
New material is scheduled in batches, so you can see how much to learn and review each day.
Due reminders
When reviews are due, the mobile app sends you a notification. Open it and you'll know what to practice today.
AI
More than answers.
Real understanding.
Solving a problem, talking through a question, taking a lesson — it all starts from the problem you're studying.
Problem solving
Solve in one click.
Solutions land in your notes.
Click “AI Solve” on a problem, and add your own approach if you like. The solution is added as a new block under the problem, so you review and export it along with your notes.
A 2 kg object falls freely from a height of 5 m. How fast is it going when it hits the ground?（g = 10 m/s²）
Chat
Got a question?
Ask until it clicks.
Click “Discuss with AI” on a problem and the problem and its answer come along into the chat. No need to restate anything — go straight to the step you're stuck on. Flash answers fast; Pro thinks deeper.
AI Tutor
One blackboard.
A lesson just for you.
Click “Explain” on a problem and the AI Tutor draws as it explains on a blackboard: notes appear line by line, figures stroke by stroke, with captions following along. Raise your hand when you're lost and it will pick up from what you asked.
Projectile = horizontal + vertical
Horizontal: no force → constant speed
Vertical: gravity only → free fall
Eliminate t:
The path is a parabola
Let's split projectile motion into two directions.
Draws as it explains
Notes appear line by line and figures stroke by stroke, highlighting whatever it is talking about.
Captions, line by line
Read along sentence by sentence. Missed something? Go back a scene and watch it again.
Raise your hand anytime
Ask whenever you're lost — no typing needed. The tutor picks up from your question.
