AI Math Solver 2026: Texify (1.1k Stars) + LLMs - The Free Stack That Beats Paid Homework Apps

Photomath and paid solvers handle textbook problems but choke on handwritten notes and your actual homework PDFs. An open-source OCR-to-LLM pipeline solves math from any input - free and private.

## The short answer The best free AI math solving stack in 2026 is **Texify** (1,127 stars, MIT) - a visual math OCR model that converts photos and scanned math into LaTeX - feeding any capable LLM for the actual solution. Total cost: zero. Privacy: complete. ## Why Texify matters Math is where generic OCR fails: equations are two-dimensional. Texify is trained specifically to convert math images into LaTeX: ```bash pip install texify texify image.png # outputs LaTeX ``` - Handles handwritten and printed math. - Outputs clean LaTeX you can feed to an LLM with the prompt: "Solve this step by step: [LaTeX]". - Local and private - your homework never leaves your machine. ## The complete pipeline 1. Photograph or screenshot the problem. 2. Texify converts it to LaTeX. 3. An LLM (Claude, GPT, or a local model) solves it with step-by-step reasoning. 4. You verify - LLMs still make arithmetic slips; treat the answer as a draft. For textbook problems, you can skip Texify and paste the problem text directly - the OCR step is only needed for images and handwriting. ## Paid apps vs this stack | Aspect | Photomath (paid) | This stack | |:-------|:----------------|:-----------| | Handwritten input | Limited | Yes (Texify) | | Cost | $10+/month | Free | | Step-by-step | Good | Good | | Privacy | Cloud | Local | ## FAQ **Is Texify accurate?** Very good on clean images; messy handwriting may need a couple of retakes. **Which LLM should I use for solving?** Any capable model works; ask for step-by-step and check each step. **Does this violate homework policies?** Using tools to understand problems is fine; submitting AI answers as your own work may violate your school's academic integrity policy. ## Related - [AI Homework Helper 2026](/post/ai-homework-helper-tools-20260803) - [AI for Students: 8 Free Tools](/post/ai-for-students-free-2026)
