New users get 10 free credits with no credit card required, and many single-purpose converters and generators run free in the browser. Paid plans: Essentials at $12/month ($6/month billed annually, $72/year) with 200 credits per month and up to 10 pages per PDF; Pro at $24/month ($12/month billed annually, $144/year) with 500 credits per month, all LaTeX tools, and up to 20 pages per PDF. Both include the browser extension. A Team plan for groups of 5+ adds centralized billing, an admin dashboard, and reimbursable invoices. ## 關鍵功能與能力 - **Anything-to-LaTeX conversion:** 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. - **Whole-document PDF handling:** 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. - **Math and diagram recognition:** Reads equations, matrices, integrals, and aligned derivations at a stated 98%+ accuracy, and can turn diagrams and plots into TikZ. - **Academic writing tools:** Drafts abstracts, summaries, and thesis statements; rewrites for clarity without losing your meaning; and looks up citations with BibTeX in the same place. - **Browser extension and free tool library:** A browser extension adds rewrite, shorten, and explain actions beside your draft, while 60+ free single-purpose converters and generators run without an account. ## 主要使用情境 - **Digitizing lecture notes (Student):** Turn a semester of handwritten notes and photographed problem sets into searchable, correctly typeset LaTeX documents instead of retyping every equation by hand. - **Rebuilding course material (Professor):** Convert old scanned handouts, problem sets, and syllabi into editable LaTeX so course material can be updated and reused rather than recreated from scratch. - **Preparing a paper or thesis (Researcher):** Move a multi-page draft, its tables, and its figures into LaTeX, then use the writing tools for an abstract, a summary, and citations with BibTeX. - **Archiving shared documents (Research group):** Use the Team plan with pooled credits, centralized billing, and admin controls to digitize a lab archive rather than one paper at a time. ## 優勢 - Handles many input types — handwriting, images, PDFs, Word, and spreadsheets — through one workflow - Produces structured, compilable LaTeX rather than plain-text approximations - Multi-page PDFs come back as a single document with sections, equations, and figures placed correctly - Free tier and 60+ no-account browser tools make quality easy to test before paying - Browser extension keeps rewriting and equation fixes inside your existing editor ## 限制 - Credit-based limits mean heavy conversion work can require a paid tier quickly - Math accuracy is high but stated at 98%+, so output still needs a review pass - Team and institutional billing details are only available on request - Best experience depends on using the browser extension alongside your LaTeX editor ## 常見問題 ### What can Underleaf convert to LaTeX?
