01The idea
What is Noesis?
One place where your material becomes a complete study system.
Bring or generate your material
Upload PDFs and notes, or describe any topic and Noesis builds the whole subject for you — syllabus, lessons and exercises.
Study with real tools
Immersive reader, handwritten notebook, speed reading and an AI tutor that knows exactly what's in your documents.
Prove you learned it
Quizzes, formal tests and coding exercises graded by AI, with progress tracked across everything you study.
02The product
Built for real studying
Clean, focused, and designed around how students actually work.
Organize your learning
Structure subjects with folders, documents, and AI-generated content — your entire library in one place.
03Pills
Study like you scroll
Pills turns any note or PDF into a full-screen feed of bite-size cards. Autoplay pacing, lo-fi in the background — and the clock stops until you answer.
Made from your files
Every deck is distilled from your own material — one idea per card, nothing invented.
Interactive by design
Quizzes, fill-the-blanks and code cards interrupt the scroll and make you answer before moving on.
An endless feed
Finish a topic and the next one queues up automatically — your whole library, shuffled into one stream.

What powers a quasar?
Extreme gravity. Bent light. One-way horizons. That's a black hole in 60 seconds.

07Everywhere
Paper meets pixel
Noesis notebooks are built for Apple Pencil. Write equations, sketch diagrams, annotate your notes — then add the web app to your home screen and study anywhere.
Apple Pencil native
Pressure-sensitive handwriting on an infinite canvas. Solve problems by hand, just like paper.
Add to home screen
Install as a web app on iOS or Android. Full-screen, instant launch — no app store needed.
Every screen, one experience
Start on your Mac, pick up on your iPad, review on your phone. Everything syncs.
08On your phone
No app store. Just add it.
Noesis is designed to be used as an app: full-screen, instant launch, home-screen icon. On iOS, installing it takes two taps.
Open noesis.app in Safari
On your iPhone or iPad — no App Store, no download, nothing to update.
Tap Share
The square with the arrow, right there in Safari's toolbar.
Add to Home Screen
Noesis lands next to your apps — with its own icon.
Once installed it runs edge-to-edge, launches from your home screen and feels native — that's how Noesis is meant to be used on the phone. Android works the same way from Chrome.
