Underleaf is an AI LaTeX assistant that converts handwritten notes, photos, PDFs, Word files, and spreadsheets into clean, compilable LaTeX, and adds academic writing tools on top.
Converts handwritten notes, photos and screenshots, scanned papers, Word documents, tables, and spreadsheets into LaTeX code that compiles rather than a rough approximation you must retype.
Uploads multi-page PDFs and lets you choose which pages to convert, returning one structured document with sections, numbered equations, tables, and figures in the right places.
Reads equations, matrices, integrals, and aligned derivations at a stated 98%+ accuracy, and can turn diagrams and plots into TikZ.
Drafts abstracts, summaries, and thesis statements; rewrites for clarity without losing your meaning; and looks up citations with BibTeX in the same place.

投稿前上傳文件，查看整體語言品質，並用修訂痕跡套用修正。
Academizer 把非正式句子學術化，Paraphraser 提供三個層級的改寫，生成器則根據文本起草標題與摘要。
