How it works

1Upload images, PDFs, or a zipScreenshots, scanned pages, or photos - phone shots of a whiteboard are fine.
2Equations read page by pageOur vision models transcribe every display equation, matrix, and aligned system faithfully, flagging unclear symbols instead of guessing.
3Parse-checked LaTeX, three waysA documented .tex file, a one-per-line .txt for quick copy-paste, and a CSV with source, label, and validation status.

ACADEMIC WRITING
Cite equations from scanned papers
Pull the equations out of an old scanned PDF as LaTeX ready to paste into your manuscript.
STUDENTS
Lecture slides into your notes
Screenshot the slide, get the LaTeX - matrices, cases, and aligned derivations included.
RESEARCHERS
Rebuild a bibliography of formulas
Zip a folder of equation screenshots and get one validated .tex file back.

Modernize old typeset material
Photograph pages from out-of-print books and get amsmath you can actually compile.
TUTORS & TEACHERS
Worksheets from whiteboard photos
Board work becomes clean LaTeX for handouts, with unclear symbols flagged for review.
