How it works
Three ways to learn with Euler
Live session
The Schrödinger Equation
Governs all of quantum mechanics
iℏ ∂ψ/∂t = Ĥψ
What does ψ tell us about the particle?
Teach me quantum physics
Euler is teaching
Ask the tutor anything
Type a topic — live board, voice, animations, step by step
Video session
LIVE
Faraday's Law
ℰ = −dΦB/dt
Changing flux → induced voltage
What does changing flux actually mean?

Your materials
Explain Q5 from my homework
Reading from Physics_HW3.pdf
Q5: Projectile Motion
h = v₀² sin²θ / 2g
Split v into x and y, solve for peak height
Euler explains from your homework
Bring your own materials
Upload homework, notes, or PDFs — ask anything, the tutor explains from your content
Study your way
Your materials. Organized. Taught.
Group your study materials into collections — exam papers, lecture notes, textbooks, YouTube playlists — and let Euler teach you directly from them.
Collections
Group files by subject, exam, or topic. Each collection is a self-contained study pack the tutor searches when you ask a question.
Any format
PDFs, lecture slides, handwritten notes, YouTube links, images, audio recordings — even scanned exam papers are processed via AI vision.
Smart retrieval
Euler finds the right page, the right paragraph, the right equation — then explains it with a live board, voice, and step-by-step animation.
Type / in the chat to scope any question to a specific collection.
For Institutions
Your curriculum.
Taught by AI. Live.
Upload your courses and lecture videos. Euler teaches each student 1-on-1 with a live board, voice, and animations — following your syllabus, not ours.
See it in action
A student asks about your curriculum. Euler teaches it live.

MIT 18.06 — Linear Algebra · Your Syllabus
Eigenvalues & Eigenvectors
When Av = λv — the vector only scales, never rotates
det(A − λI) = 0
← the characteristic equation to find λ
What happens to vectors that aren't eigenvectors?

Onboarding
Three steps to give every student a private tutor
1
Upload your curriculum
Lecture videos, PDFs, syllabi, question banks — any format. Euler processes and indexes everything.
2
We build the teaching layer
Euler maps your curriculum into structured lessons with teaching plans, checkpoints, and assessments.
3
Students get a private tutor
Each student learns at their own pace. You get analytics on mastery, engagement, and who needs help.
Not a chatbot
Other AI tools answer questions. Euler teaches.
Live visual board
Diagrams, equations, animations — not walls of text
Follows YOUR syllabus
Teaches your curriculum, your way, lesson by lesson
Assesses understanding
Inline questions, mastery tracking per concept per student
Video follow-along
Your lecture videos + AI tutor side by side
Schedule a Demo
Tell us about your institution and we'll set up a walkthrough.

My Materials
How it works
1.
Upload
Drop a PDF, paste a YouTube link, or type notes. Euler reads and understands it.
2.
Ask anything
Start a session with your collection scoped. "Teach me chapter 3" or "explain this formula."
3.
Learn deeply
Animated explanations, practice problems, and Q&A — all grounded in your specific content.

What do you need help with?
Your tutor finds the right material, builds a plan, and teaches you live.
Explain eigenvalues simply
Prep me for a calculus midterm
I'm stuck on Gauss's law
Teach me wave equation from scratch
Quiz me on angular momentum
What happens next
1
Finds the right material — searches across all courses for the best content.
