Solve Any Math Problem, Step by Step
Type a problem or snap a photo and OneStudy works through it line by line — showing every step of the reasoning, with an interactive visualization when it helps. It even checks its own work before it shows you the answer.

From Homework to Higher Math
However the problem shows up, OneStudy works through it the way a great teacher would.
Algebra & Calculus
Equations, derivatives, integrals, limits — worked out step by step so you learn the method, not just the number.
Physics & Chemistry
Set up the problem, apply the right formula, and follow the reasoning through to a checked answer.
Geometry & Graphs
See the shape or curve as an interactive visualization, not just a line of algebra.
Word Problems
OneStudy reads the problem, pulls out what matters, and shows how it gets from the words to the answer.
From material to mastery in three steps
Enter the problem
Type it in or snap a photo of the page. Handwritten or printed, one problem or a whole set.
Watch it solve
OneStudy works through the problem step by step and, where it helps, draws an interactive visualization you can explore.
Understand it
Ask the built-in tutor to explain any step, try a similar problem, or go deeper on the concept behind it.
Answers You Can Actually Learn From
A number off a calculator teaches you nothing. OneStudy shows the whole path — and makes sure it's right.
Every Step Shown
See the full working, line by line, so you can follow the method and reproduce it yourself on the exam.
Interactive Visualization
Where a graph or diagram makes it click, OneStudy builds an interactive one you can explore, not just a static picture.
Checks Its Own Work
Before showing you the answer, OneStudy verifies its solution behind the scenes, so the steps you're learning from are sound.
Solve From a Photo
Snap a picture of a problem — handwritten or printed — and OneStudy reads it and gets to work.
Ask the Tutor Anything
Stuck on one step? The AI tutor re-explains it, gives a hint, or walks you through a similar problem.
Math & Science
From pre-algebra to calculus, and physics to chemistry — one solver for the quantitative side of every class.
AI Math Solver vs. a Plain Calculator
A calculator gives you a number. OneStudy gives you the method, the picture, and a tutor — so you can do the next one yourself.

How Students Use the Math Solver
Homework that teaches
Works through problem sets step by step and asks the tutor to explain the moves that don't click.
From photo to solution
Snaps a picture of a problem and follows the full setup and reasoning to a checked answer.
Practice the method
Re-solves past problems to drill the method, then tries similar ones with the tutor.
Set-up made clear
Sees how the right formula gets applied instead of guessing which one to use.
AI Math Solver — your questions, answered
Math from pre-algebra through calculus — equations, derivatives, integrals, graphs — plus quantitative physics and chemistry problems, including word problems.
Yes. Snap a picture of a printed or handwritten problem and OneStudy reads it and solves it step by step, or type it in directly.
It shows the full working, line by line, and where a graph or diagram helps it builds an interactive visualization — so you learn the method, not just the result.
OneStudy verifies its own work behind the scenes before showing you the solution, and you can ask the AI tutor to walk through any step you're unsure about.
That's the point. The built-in tutor will re-explain any step, give hints, or generate a similar problem so you can practice the method yourself.
Yes, you can solve problems for free. OneStudy+ unlocks higher limits and every study tool.
One upload, every study tool
OneStudy isn't one feature — it's a whole study system. Explore what else your material can become.
