\compare{vs-mathpix}
Two tools. Completely different jobs. Here's what each one actually does — and why you might need both.
Mathpix reads images and outputs LaTeX. FormaTeX reads LaTeX and outputs PDFs. One converts TO LaTeX; the other compiles FROM LaTeX. There is no meaningful overlap.
Image → LaTeX
Mathpix uses AI/OCR to extract mathematical expressions from images, PDFs, and handwritten notes and converts them into LaTeX or MathML markup.
LaTeX → PDF
FormaTeX compiles LaTeX source code into pixel-perfect PDFs using a managed TeX Live environment. It's a compilation API for developers.
\section{Feature Comparison}
A side-by-side breakdown across the dimensions that matter — so you can choose the right tool for the job.
| Feature | Mathpix | FormaTeX |
|---|---|---|
| Primary function | Converts images/PDFs/handwriting to LaTeX | Compiles LaTeX source to PDF |
| Input | Images, PDFs, handwriting | LaTeX source code (.tex) |
| Output | LaTeX, MathML, Markdown | PDF document |
| Use case | Digitising existing content | Generating new documents |
| AI/ML component | Yes — core product | No — deterministic compiler |
| Requires LaTeX knowledge | Optional (produces LaTeX for you) | Yes (you write the LaTeX) |
| Has a REST API | Yes | Yes |
| Free tier | Limited OCR quota | 100 API compilations/month |
\section{How They Complement Each Other}
If you're working with existing physical or digital content that contains math, Mathpix + FormaTeX is a natural pipeline: OCR first, compile second.
Scan your handwritten notes or a textbook page with Mathpix — get clean LaTeX markup extracted automatically from the image.
Edit and expand the LaTeX in your editor or the FormaTeX Playground. Add structure, formatting, and any additional content.
Compile with the FormaTeX API and receive a professional, pixel-perfect PDF ready for sharing or publication.
