askNib vs Photomath: the Photomath alternative that explains why
askNib is a Photomath alternative for students who want the why, not just the steps: type or paste your problem and Nib teaches it live, drawing each step on a whiteboard while his voice explains why it works. Stop at any step to ask about it, keep the lesson to replay before the test, and use the same tutor for physics, chemistry, history or anything else, in any browser. Photomath is a math app for iPhone and Android2.

Where is askNib better than Photomath?
- Every subject: physics, chemistry, biology, history and literature as well as math. Try Why does cobalt always turn glazes blue?.
- Each step drawn and said out loud: Nib draws the step on the board as his voice explains why it works, with captions. Watch Why does a light bulb glow?.
- Ask in the middle of the drawing: pause at any step, ask why, and Nib draws that part again, his way. Every part of the binary search series has its own ask.
- Any browser, nothing to install: a Windows PC, a Mac or a Chromebook as well as a phone. Start at asknib.com.
- A whole unit as a series of parts, played in order, like the dynamic programming series.
- Free to watch with no account: every public lesson, and any lesson shared with you, plays without signing in (askNib help).
How does askNib work a math problem?
Type the problem the way your worksheet says it, or paste it in, and ask Nib to work it. He starts drawing within seconds and goes one step at a time: each step appears on the board as his voice explains what is happening and why it is allowed, with captions on screen.
If a step loses you, pause and ask, for example “why did you divide both sides by 3?”. Nib keeps the thread and draws that part again, his way. When you are done, the whole lesson stays as a page: every step's words and drawings, in order, to reread before the test.
Why do students switch from Photomath to askNib?
- They want the why, explained out loud the way a teacher works a problem at the whiteboard.
- Their homework goes beyond math: physics, chemistry, biology, history, literature and computing.
- They study on a laptop or a Chromebook, in any web browser.
- They have a whole unit to learn, part by part, in order.
Is there an app like Photomath for chemistry, physics and every other subject?
Yes: askNib. Ask a chemistry, physics, biology or history question the same way you would type a math problem, and Nib draws the answer step by step while he explains it out loud. Open the chemistry and physics lessons below to see it.
What does an askNib lesson look like?
Real lessons on askNib, each one drawn and explained by Nib. Open one to read it step by step, or press play to watch him draw it.
- How can 20 guesses find one number in a million? (math, a series page): halving the range each guess, until twenty guesses cover 2²⁰ − 1 = 1,048,575 numbers.
- What is dynamic programming, really? (math and computing, a series page): why the obvious Fibonacci recursion needs about forty billion calls at n = 50, and storing each answer takes about fifty steps.
- Why does cobalt always turn glazes blue? (chemistry): cobalt's electrons soaking up red, orange and yellow light, so blue is what comes back.
- Why does a light bulb glow? (physics): how a tungsten filament fights the current, heats to about 2,700 °C and glows, sealed in argon so it never burns up.
- How does wifi go through walls? (physics and tech): 12-centimeter radio waves meeting a wall: some bounce, some soak in, some push through.
What is askNib, and who is it for?
askNib is a live AI tutor that draws. Ask anything, or give it your notes, a PDF or a link, and Nib, a marker, teaches it on a whiteboard: he starts drawing in seconds and talks you through the idea in about a minute, with captions. Lost at a step? Ask back, and he draws that part. Every lesson is kept as pages you can replay and share, and a whole topic becomes a series.
askNib is for:
- High school and college students who want a concept to click before the test
- Students who get lost at one step and want to ask about exactly that step
- Visual learners: you see the idea built on the board, step by step
- Parents who want their teen to understand the homework, with a lesson they can watch together
Photomath's niche is the phone camera: scanning a math problem with its app2.
Questions students ask
What is a good Photomath alternative that explains the steps?
askNib. Type or paste the problem and Nib works it step by step, drawing each step on a whiteboard while he explains out loud why it happens. You can stop him at any step to ask why, in any subject.

Will askNib help me understand, not just copy the answer?
Yes. Nib teaches the problem one step at a time and says why each step happens, so the next problem makes sense on your own. Stop him at any step and ask about it.
Can askNib help with word problems, geometry and calculus?
Yes. Type or paste the problem, from any branch of math, and Nib works it step by step, drawing what each step means while he explains it out loud.
Is askNib free?
Yes. Every public lesson, and any lesson shared with you, plays with no account1, and asking your own questions is free with a Google sign-in.
Photomath or askNib: which is better for understanding math?
For understanding, askNib: Nib draws each step and explains why it happens out loud, at your pace, and you can ask about any step until it clicks.
