手写笔记、PDF 批注与 AI 学习工具，都在同一块画布上
低延迟墨迹、防误触手掌识别、划掉即擦除以及手写转文字，让书写接近纸笔手感。
导入合同、论文或教材，用手直接标注，批注可搜索并可干净导出。
同时检索键入文本、手写与速写，并把笔记转成摘要、思维导图或结构化计划。
在共享笔记本、文档和白板上同时协作，不再有版本冲突或反复传文件。
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.
