Underleaf

Description

Underleaf is an AI-powered platform for academic writing and LaTeX, built for students, professors, and researchers. Its core capability is conversion: it turns handwritten notes, photos, screenshots, whiteboard shots, single equations, tables, spreadsheets, Word documents, and multi-page PDFs into clean, compilable LaTeX, and it can convert diagrams and plots to TikZ. Math converts at 98%+ accuracy, including matrices, integrals, and aligned multi-line derivations, with a typeset preview before download.

Beyond conversion, Underleaf offers academic writing tools that draft abstracts, tighten paragraphs, and summarize dense sections while keeping the user's terminology and notation, along with citation lookup and BibTeX generation in the same place. Multi-page PDFs come back as one structured document with sections, numbered and referenceable equations, tables, and figures in the right places.

Everything runs in the browser with no installation, and an optional Chrome extension puts the same AI assistance beside a user's draft to rewrite, shorten, or explain selections, insert or replace text, find citations, and convert images to LaTeX inline. Underleaf also provides 60+ free tools, including image-to-LaTeX, Excel-to-LaTeX, a TikZ generator, and a 3D graphing calculator, plus learning tutorials and a verified AI/ML conference deadline calendar.

Underleaf emphasizes privacy, processing only submitted content over encrypted connections and not storing document content permanently. It offers a free plan with 10 credits per month and no card, Essentials at $4.99/month billed annually (200 credits, up to 10 pages per PDF), and Pro at $9.99/month billed annually (500 credits, up to 20 pages per PDF), plus team plans. It reports 50,000+ academic users across 200+ universities and 240K+ pages converted.
