Hit Mathpix free-tier walls? Extract equations from scanned academic PDFs into Overleaf-ready LaTeX—unlimited local runs, zero uploads.
Built for confidential workflows — files stay in your browser memory.
Cloud equation OCR is convenient until the monthly page cap hits mid-thesis. A local scanned-PDF path runs symbolic OCR in WebAssembly: fractions, subscripts, limits, and array grids become compilable LaTeX without shipping unpublished pages to a vendor GPU. Use this when the source is a scan; prefer the equation crop tool for clean digital PDFs.
Students digitize older journal scans. Instructors recover problem-set formulas from photocopied packets. Researchers avoid SaaS training policies on grant drafts. Anyone who needs a mathpix alternative free no limit for batch equation grabs.
Open a page-image or camera-scanned math PDF in the local extractor.
Select the formula or table region for symbolic OCR.
Preview and paste into your TeX editor or paper repo.

For handwriting, use the specialized handwritten notes converter. This tool is tuned for scanned printed math and textbooks.
A WebAssembly OCR/symbolic path runs in a browser thread on your CPU—no hosted GPU quota, so it works as a mathpix alternative free no limit for many workflows.
Not on the local path. Conversion stays in client memory after the page assets load.
Prefer PDF to LaTeX Equations for clean digital formula PDFs. Use this page when the source is primarily a scan.
