What you pay for
- On your computer: nothing per use. You pay in disk space, memory and electricity, at lower quality.
- publik API: publik’s published price for each use, in dollars, from your publik balance. It is above the model’s cost; the difference runs publik and pays the app’s builder.
- Your own key: the provider’s price, billed to an account you keep with the provider.

The Modern Open-Source AI Math Solver, Homework Assistant & Graphing Calculator
A community-first, privacy-respecting alternative to proprietary platforms like MathGPT, Photomath, and Symbolab.
Features · Quickstart · Docker Deployment · Testing
Why OpenMath?
Most AI math applications lock step-by-step solutions behind subscription paywalls, sell student data, or fail when network connectivity drops.
OpenMath runs locally first:
- Free and open-source with no paywalls or subscriptions.
- Works offline out of the box with zero mandatory API keys, using a local symbolic evaluation engine and benchmark corpus.
- Supports pluggable multi-model AI (publik, Google Gemini, OpenAI, Groq, Ollama) for multimodal reasoning and handwriting recognition.
- Includes a cursor-aware virtual math keyboard, KaTeX rendering, and 2D Cartesian graphing.
Key Features
| Feature | OpenMath (Open-Source) | MathGPT / Proprietary Apps |
|---|---|---|
| Step-by-Step Derivation | Full step breakdown with explanations | Gated behind $19.99/mo |
| Photo / OCR Solver | Client-side pre-processing + vision | Limited free daily credits |
| Formula Keyboard | Categorized LaTeX palette (Popular, Trig, Calc, Greek) | Available |
| Graphing Calculator | Dual engine: Native Canvas plotter + GeoGebra embed | Iframe only |
| Study Suite | SM-2 Spaced Repetition Flashcards + Timed Exams | Paywalled |
| Homework Auto-Grader | 4-point AP-style rubric analysis & feedback | Paywalled |
| Offline Self-Hosting | 100% functional with zero API keys required | Cloud proprietary only |
Core Modules
1. AI Homework Solver
- Step-by-step mathematical reasoning with formatted LaTeX display math ($$...$$) and inline math ($...$).
- Problem formalization, intermediate derivations, and final answers highlighted in $\boxed{\text{canonical format}}$.
- "Plot in Grapher" action chip detects equations and passes them into the graphing calculator.
2. Virtual Math Keyboard & Formula Palette
- Categorized palettes:
- Popular: $+$, $-$, $\times$, $\div$, $\frac{a}{b}$, $x^2$, $x^n$, $\sqrt{x}$, $\pi$, $\infty$, $\pm$, $\le$, $\ge$
- Algebra: $x$, $y$, $z$, $|x|$, $\log$, $\ln$, $x_1$, $f(x)$, $n!$, $\binom{n}{k}$
- Calculus: $\frac{d}{dx}$, $\int$, $\int_a^b$, $\lim_{x \to 0}$, $\sum$, $\partial$, $\nabla$
- Trigonometry: $\sin$, $\cos$, $\tan$, $\arcsin$, $\arccos$, $\arctan$, $\sec$, $\theta$
- Greek & Logic: $\alpha, \beta, \gamma, \delta, \lambda, \sigma, \omega, \Delta, \in, \cup, \cap, \implies$
- Cursor-aware insertion with auto-selection of template parameters.
3. Interactive 2D Graphing Calculator
- Cartesian coordinate engine rendered on HTML5 Canvas.
- Real-time function stack: plot polynomials, trigonometric waves, exponentials, and logarithms.
- Live crosshair coordinate readout: $(x, y)$.
- Zoom, pan, and reset controls with mouse and touch interaction.
- GeoGebra embed toggle: 1-click switch to the GeoGebra 2D/3D applet for geometric constructions.
4. Spaced Repetition Flashcards & Study Suite
- Built-in SuperMemo SM-2 algorithm for review scheduling.
- Interactive flip cards with question prompts and mathematical proofs.
- Rate recall difficulty (Again, Hard, Good, Easy) to calculate dynamic review intervals.
5. AP & College Diagnostic Exams
- Timed 10-minute diagnostic tests featuring Multiple Choice and Free Response questions.
- Instant automated scoring and step-by-step solution keys.
6. FRQ & Assignment Auto-Grader
- Rubric-based evaluation scoring student derivations across 4 dimensions:
- Conceptual Setup & Formula Selection (1 pt)
- Intermediate Algebraic / Calculus Derivation (1 pt)
- Dimensional & Unit Consistency (1 pt)
- Final Accuracy & Boxed Value (1 pt)
Docker Deployment
Deploy OpenMath with a single command using Docker:
docker compose up -d
The application will be live at http://localhost:3000.
