Underleaf

Underleaf is an advanced artificial intelligence platform designed for automated document-to-LaTeX conversion. Its primary function is to transform handwritten notes, PDF files, whiteboard photos, and screenshots into clean, ready-to-compile LaTeX code in seconds. This tool is specifically tailored for the academic sector, proving highly useful for students, professors, and researchers who need to digitize scientific or technical content without having to manually transcribe complex equations on their computer.

Underleaf’s operation is based on AI models specialized in recognizing characters and mathematical structures. The process is straightforward: the user uploads a file (whether a multi-page PDF, a PNG/JPEG image, or a spreadsheet), the system processes the content while maintaining the structure of matrices, tables, and formulas with over 98% mathematical accuracy, and finally allows for a preview of the typeset result before downloading the source code. As a browser-based tool, it requires no additional software installation, facilitating access from any device.

Among its most notable capabilities and practical benefits are:

• Handwriting-to-LaTeX Conversion: Transform paper class notes into structured, professional digital documents.
• Full Document Processing: Upload large files to generate a single document with numbered and referenceable sections, figures, and equations.
• TikZ and Matrix Generator: Specific AI-powered tools for quickly creating complex diagrams and algebraic structures.
• Academic Writing Assistant: Includes features to draft abstracts, improve paragraph clarity, and search for bibliographic citations to automatically generate BibTeX files.
• Bidirectional Conversion: In addition to generating code, it offers utilities to convert Excel to LaTeX, Word to LaTeX, and even the reverse process.

The tool integrates seamlessly into the workflow via a Chrome extension, which allows users to rewrite, shorten, or explain text fragments directly from the browser while working on a draft. This optimizes productivity by eliminating the need to constantly switch between tabs.

Regarding security and privacy, Underleaf guarantees that documents are processed through encrypted connections and that content is not permanently stored on its servers. This technological solution allows users to write scientific papers faster and with flawless formatting, removing the manual workload involved in coding dense mathematical formulas and complex tables.
