Install Knox Knows for Chrome and keep your AI study companion one click away.
Knox starts with the question in front of you, then stays with you while you study. Build a guide, practice with flashcards, or let Knox quiz you until it clicks.
Every AI homework app promises "answers." Here's what we actually did differently.
Most apps stick free users on a lite version to push you to upgrade. Knox gives you the full AI on day one. Paying only removes the usage limit — it doesn't unlock better answers.
Other apps make you choose "Answer mode" or "Solver mode" or "Tutor mode" before you even type. Knox reads what you actually need from how you ask. Say "quiz me" and it teaches. Say "just tell me" and it tells you.
You won't get "Final Answer:" / "Explanation:" / "Key Points:" like it's a filled-out form. Knox answers the way a smart friend would — direct, natural, with real reasoning. No filler.
Point your camera at a worksheet, whiteboard, textbook, or your own handwriting. Knox reads it, confirms what it sees so you know it got the right problem, then helps.
No modes, no menus. Type the way you'd actually ask a friend — Knox reads what you need. 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.
"Don't just give me the answer — teach me how."
Sounds good. Start with 3x² — there's a rule for x-to-a-power terms. What do you think it becomes?
"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.
