Handwriting to LaTeX Converter

Turn messy notes into clean, compile-ready LaTeX—instantly. Perfect for math, research, exams, and lecture scribbles.

Try it now → Upload a photo or PDF of your notes and get LaTeX you can edit in Octree.

Math-first accuracy: equations, matrices, integrals, proofs
Layout aware: titles, sections, lists, inline math vs display math
Batch mode: scan a notebook once → get a structured `.tex` project
Private by default: opt-in cloud; on-prem available for labs & firms

How it works

Upload images (JPG/PNG/HEIC), scans, or PDFs
Enhance (deskew, denoise, contrast boost)
Recognize handwriting + symbols (vision OCR + math parser)
Structure into LaTeX (sections, labels, numbered equations)
Review & edit in Octree with AI diffing and one-click compile

What you can upload

A4/Letter scans from phones or flatbed scanners
Whiteboard photos (take straight-on; avoid glare)

9\lim_{x \to 2} \frac{x^2 - 4}{x - 2} \text{ is the "0" case}

11The function isn't defined at \( x = 2 \).

13Manipulate algebraically by factoring:
14\[
15\frac{(x + 2)(x - 2)}{(x - 2)} \to \lim_{x \to 2} (x + 2) = 4

Why Octree over generic OCR?

Built for LaTeX: knows `\\\\begin{align}`, `\\\\frac`, `\\\\sum`, `\\\\pmatrix`, labels/refs
Inline vs display math: smart detection + consistent formatting
Semantic cleanup: replaces ambiguous symbols, normalizes spacing, escapes `_` `#` `%`
AI diffing: accept/reject changes like code review for math
Speed: optimized pipeline + on-device pre-processing options

Tips for best accuracy

Write clearly; keep symbols distinct (e.g., 111 vs lll vs ∣|∣)
Use lined/dot grid paper; avoid shadows/glare
Shoot straight-on; include margins so we detect layout
Prefer black/blue pen; avoid light pencil on glossy paper

Privacy & Compliance

Private by default: your files aren't used to train models unless you opt-in
Regions & retention: choose data region; set auto-delete windows
On-prem/self-hosted: for universities, finance, and legal teams
Access controls: SSO/SAML, audit logs, role-based permissions
