Every AI homework app promises "answers." Here's what we actually did differently.
Every plan uses the same AI. Start free, then upgrade for more questions, files and study tools.
Learn with worked examples, one-step questions and hints. Knox teaches a small piece, then helps you try it yourself.
Ask in your own words. Knox gives a direct explanation, and you can ask follow-up questions whenever something doesn’t click.
Bring a worksheet photo, handwritten notes, PDF, Word document or PowerPoint. Knox reads what you share and helps you work through it.
Ask Knox the way you'd ask a friend — or turn on Learn mode to be taught step by step. Real examples:
"What's the derivative of 3x² + 5x − 2?"
The derivative is 6x + 5. Power rule — bring the exponent down, subtract one. Constants disappear.
"Why do leaves change color in the fall?"
Let’s figure it out together. Leaves are green because of a pigment that helps them use sunlight. Do you know what it’s called? Tap an answer · Hint · step 1 of 3
"I got 6x + 5x. Is that right?"
Close — one slip. First term's right. But 5x becomes 5, not 5x — x¹ turns into x⁰ = 1.
Tell Knox what you’re studying — or drop in your notes, slides or a photo — and it makes a deck with pictures (2 credits on the free plan, unlimited with Knox Plus). Smart review brings back the cards you miss.
A full scientific calculator built in — trig, powers, roots, logs and more. Stuck on why? Tap Explain it and Knox walks you through the math.
Chats, Learn lessons and flashcard decks save to your account, so you can start on your laptop and finish on your phone.
Free forever · no credit card
From 4th grade math to college organic chem — Knox has you covered.
Not on the list? Knox handles it anyway. Just ask.
