See the math in full depth
Describe your problem in words, get an exact 3D model and a step-by-step solution.
Formulas don't explain space.
Depth does.
A flat drawing won't show the angle between faces. A blackboard won't show how a plane cuts a solid. Depth will, and you'll get it.

From plain text prompt to crystalline comprehension
Three intuitive steps that transform complex spatial geometry into an engaging interactive experience.
Describe the problem in words
Type the condition as plain text or a formula, just like in a textbook. Depth parses it for you.
- Russian, English, O'zbekcha
- Text or formula
- Automatic problem parsing
- School and university problems
An exact 3D model
A deterministic engine builds the correct figure instantly, with no AI hallucinations.
- Symbolic CAS engine
- WebGL, 60 FPS
- Rotate, zoom, cross-sections
- 100% computational accuracy
Step-by-step solution
A clear explanation with formulas, highlighted in sync right on the 3D model.
- A formula at every step
- Highlighted on the figure itself
- From the general to the specific
- A verified final answer
All of mathematics in 3D
From school geometry to university calculus, one visual engine for every topic.
- Solid and plane geometry
- Function graphs and surfaces
- Vectors and trigonometry
- Complex numbers, limits
Mathematics you can truly trust
We combined rigorous symbolic mathematics with state-of-the-art interactive spatial 3D rendering.
Always accurate
Calculations are executed by a deterministic Computer Algebra System (CAS), not probabilistic AI. Mathematical hallucinations are impossible.
Visible in 3D
Not endless dry text, but a tangible WebGL figure: rotate 360°, inspect vertices, cut with dynamic planes.
Explains step-by-step
Pedagogical derivation from first principles, highlighting exact geometric components as you read each equation.
Built for those who learn and those who teach
Two workflows, one mission: make mathematics intuitive, tangible, and lucid.
Grasp complex concepts at a glance instead of struggling through 10 hours of rote memorization.
- Solve any challenging problem from homework or exams (SAT, IB, AP Calculus, national tests)
- Rotate 3D models from any perspective: textbook diagrams won't look like a tangle of lines anymore
- Step-by-step mathematical proofs show where every single number comes from and which theorem applies
- Develop genuine spatial intuition essential for careers in Engineering, AI, Computer Science, and Physics
Frequently asked questions
Can I use Depth for free?
Yes. The Free plan gives you 5 solutions a day with full 3D models and step-by-step explanations, no card required.
Which plan is right for me?
Free is for trying Depth, Student is for learning and exam prep, Pro adds sharing, exports and every topic for teachers, tutors and advanced learners, and Schools brings Depth to a whole institution.
How accurate are the solutions?
Depth computes answers with a deterministic math engine instead of guessing with a language model, so every number, angle and step is exact and reproducible.
Can I switch between monthly and yearly billing?
Yes. You can change your billing period or plan at any time; the change applies from your next billing cycle.
How do I cancel my subscription?
You can cancel any time from your account settings. You keep access to your plan until the end of the paid period.
Do you offer pricing for schools and learning centers?
Yes. The Schools plan is priced per institution with unlimited seats, onboarding and invoice billing. Contact us and we will put together an offer.
I have another question about pricing.
