What is Underleaf?
Underleaf is a LaTeX assistant for students and researchers that converts existing material into LaTeX source. It accepts handwritten notes, photos, screenshots, pictures of a whiteboard, individual equations, tables, spreadsheets, Word files and PDFs of many pages, and diagrams or plots can be turned into TikZ. A PDF comes back as a single structured file in which sections, equation numbering, tables and figures are preserved, and you choose which pages to process. The result is shown as a typeset preview, can be corrected with AI edits, and is then copied or downloaded. Writing tools draft abstracts, summaries and thesis statements, rewrite passages for clarity and look up citations with BibTeX output. A Chrome extension brings the same help next to a draft in the browser, and more than 60 free tools run without an account. Everything works in the browser. A free plan provides 10 credits a month; Essentials, Pro and Team plans add more.
