Animal cell cross-section

Biology

Cell Division — Mitosis

○ Prophase: chromatin condenses into chromosomes
○ Metaphase: chromosomes align at cell plate
○ Anaphase: sister chromatids pulled to opposite poles
⚑ PMAT — 4 stages in order (mnemonic)
abc

Right triangle a² + b² = c²

Mathematics

Pythagorean Theorem

a² + b² = c² — sides of a right triangle
c is always the hypotenuse (longest)
★ Proof: 3² + 4² = 9 + 16 = 25 = 5²
⚑ Only works for 90° triangles!
OHH104.5°

Water molecule polar covalent

Chemistry

Chemical Bonding — H₂O

○ 2 hydrogen atoms covalently bonded to oxygen
○ Bond angle 104.5° — bent geometry
Polar molecule — δ⁻ on O, δ⁺ on H
★ H-bonds explain high boiling point

Physics

Newton's 2nd Law — F = ma

F = ma — Force equals mass × acceleration
○ Net force causes change in velocity
★ Unit: Newton (N) = kg·m/s²

Binary tree O(log n)

CS

Big-O Time Complexity

O(1) — constant time (hash lookup)
O(log n) — binary search, halves each step
O(n log n) — merge sort, heap sort
★ O(n²) → avoid for n > 10,000!

Everything you need to study smarter

Structured Notes

Chapters, bullet points, and key concepts extracted straight from the lecture — formatted like you would write them yourself.

Flashcards

Auto-generated question/answer pairs covering the most important concepts so you can quiz yourself and lock in knowledge.

Introduction to Neural Networks

Stanford CS229 · Lecture 7 · Generated in 42s

Chapter Notes
Chapter 1 — What is a Neural Network?
○ A neural network learns patterns from data using layered nodes
○ Inspired by the human brain — neurons and synapses
○ Layers: input → hidden → output
— Key concept: Backpropagation adjusts weights via gradient descent
○ Activation functions (ReLU, sigmoid) introduce non-linearity

I watched a 3-hour MIT lecture on algorithms and had complete structured notes in under two minutes. The flashcards alone saved me probably four hours of review prep before my qualifying exam.

I learn entirely from YouTube — Fireship, Theo, all of it. Study Notes turns those videos into actual study material I can review later. It finally feels like learning, not just watching.

Khan Academy biochemistry videos are great but dense. Now I paste the URL and get a clean outline with key terms highlighted and practice questions at the end. My study sessions are half as long.

The Mermaid diagrams are genuinely impressive. For machine learning topics with lots of moving parts, having a visual flowchart auto-generated from the lecture is something I didn't know I needed.

Frequently asked questions

Is this just another AI summary, or full lecture notes?+

Three modes. Summary gives you chapters and flashcards — fine for skim. Full Lecture Notes (the default for longer lectures) gives you a 10–20 page structured notebook with every definition, formula, and example from the lecture — built for cram. Worked Solution transcribes step-by-step exam-walkthrough videos with every equation. You pick the mode when you submit a video (or use the admin library page for curated content).

What types of YouTube videos work best?+

University lectures, course recordings, conference talks, and tutorials — anything with clear speech and captions. Particularly strong on exam-prep content: math, sciences, engineering, medicine, law. Music videos or speech-less videos are not supported.

How long does it take to generate notes?+

Most lectures under 30 minutes are ready in under 60 seconds. Longer videos (1–2 hours) take 2–4 minutes for the text notes; Pro’s hand-drawn frame visuals add a few minutes more.

What exactly is included in a set of study notes?+

Each note set includes: structured chapters with handwritten-style bullets, AI flashcards, exam-style practice questions, auto-generated diagrams, and typeset math (KaTeX). Pro adds hand-drawn diagrams and equations re-created from the actual video frames. Export to PDF or PNG with one click.

Does it work for non-English videos?+

Yes. Notiq supports 19 output languages — pick one when you submit the video and the notes come out in that language, regardless of what the lecturer speaks. An English lecture can produce Romanian, Spanish, Korean, or Arabic notes with all the math equations preserved exactly.

What is the difference between Free and Pro?+

The Free plan gives you 3 lifetime note sets on videos up to 20 minutes — full handwritten-style notebooks with flashcards, exam questions, typeset math and auto-generated diagrams. Pro removes those limits and adds the standout feature: hand-drawn diagrams and equations re-created from the actual video frames. You also get 30 note sets per month, videos up to 5 hours, priority processing, watermark-free PDF/PNG exports, and email support.

Can I export my notes?+

Yes. Every note set exports to PDF or PNG with one click — keep them on your laptop, print them, or share them with classmates. Free exports carry a small Notiq watermark; Pro exports are watermark-free.

Is my data private?+

Yes. Your notes are private to your account. We do not share note content with third parties or use it to train AI models. See our Privacy Policy for full details.

Can I cancel my Pro subscription at any time?+

Absolutely. You can cancel your subscription from your account settings at any time. You will retain Pro access until the end of your current billing period with no further charges.
