## Underleaf

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.

**價格與方案:** Freemium. 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.

- **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.

**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

**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
