Underleaf is an AI-powered LaTeX assistant that converts handwritten notes, photos, PDFs, spreadsheets, and Word documents into clean, compilable LaTeX code in seconds. Designed for students, professors, and researchers, it eliminates hours of manual retyping and formatting work, achieving 98%+ accuracy on mathematical equations.

Who It's For & What Problems It Solves

Academic professionals waste countless hours manually transcribing handwritten lecture notes, converting scanned papers, or reformatting documents into LaTeX. Underleaf solves this by accepting virtually any input format—photographed whiteboards, scanned journal articles, Excel spreadsheets, or Word documents—and returning structured LaTeX code that compiles immediately. Trusted by 50,000+ academics across 200+ universities, it has converted over 240,000 pages with exceptional mathematical accuracy.

Key Features & Capabilities

• Multi-Format Conversion: Accepts handwritten notes, PDFs, photos, screenshots, equations, tables, spreadsheets, and Word documents
• Whole Document Processing: Convert multi-page PDFs (up to 10-20 pages depending on plan) into single structured documents with sections, numbered equations, tables, and figures
• 98%+ Math Accuracy: Handles complex equations, matrices, integrals, and multi-line derivations with exceptional precision
• AI Writing Assistance: Draft abstracts, rewrite paragraphs for clarity, generate summaries, and look up citations with BibTeX export
• Chrome Extension: Access conversion and writing tools directly alongside your draft without switching tabs
• 60+ Free Tools: Image to LaTeX, PDF to LaTeX, Table generators, Citation generators, TikZ generators, and more
• Instant Preview: See typeset results before downloading to verify accuracy

Typical Workflows

Upload a document (photo, scan, or PDF) in your browser—no installation required. The AI extracts equations, tables, and structure intact, returning LaTeX source code you can immediately compile. Use the writing tools to draft abstracts, improve clarity, or generate citations. The Chrome extension lets you rewrite, shorten, or explain selected text while working in your existing LaTeX editor.

What Sets It Apart

Underleaf combines conversion accuracy with a full academic writing toolkit. Unlike simple OCR tools, it understands mathematical notation and document structure, preserving numbered equations and references. The platform prioritizes privacy—only submitted content is processed over encrypted connections, and documents aren't stored permanently. With simple browser-based access and 60+ free tools requiring no account, it removes barriers while delivering professional results.
