## Underleaf

Underleaf focuses on the gap between what researchers already have — scanned notes, photos of a whiteboard, a journal PDF, a spreadsheet of results — and the LaTeX source they need. You upload the source material, pick the pages you care about when it is a multi-page document, and the tool returns one structured LaTeX document with sections, numbered equations, tables, and figures placed where they belong. It claims 98%+ accuracy on equations, including matrices, integrals, and aligned multi-line derivations, and shows a typeset preview before you download anything.

Beyond conversion, Underleaf bundles the writing work that usually happens afterwards: drafting abstracts and summaries, generating thesis statements, rewriting paragraphs for clarity while keeping your terminology, and looking up citations with BibTeX output. A browser extension brings the same rewriting, shortening, and explaining actions next to whatever draft you already have open, so you do not have to copy text into a separate tab.

The site reports 50,000+ academic users across 200+ universities and 240,000+ documents converted. A large set of single-purpose free tools (image to LaTeX, PDF to LaTeX, Excel to LaTeX, TikZ generator, table generator, citation generator, and more) can be used without an account, which makes it easy to test quality before paying.

**Pricing & Plans:** 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.

**Strengths:** 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

**Limitations:** 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

## Writefull

Writefull is a writing and proofreading tool designed for academics. Instead of relying on general-purpose language models, it uses models trained on millions of journal articles, so its feedback is tuned to the conventions, phrasing, and style of research writing. That calibration is why it tends to catch problems that generic proofreaders overlook, from awkward collocations to non-native phrasing that reads oddly in a paper.

The product lives where researchers already write. Writefull for Word delivers automatic language feedback inside Microsoft Word and can paraphrase, change style, explain, or summarize text. Writefull for Overleaf works within your LaTeX code and adds TeXGPT, which writes LaTeX for tables, formulas, and equations on demand. For pre-submission checks, Writefull Revise lets you upload a document, see its overall language quality, and fix errors with Track Changes. A set of AI widgets rounds things out: the Academizer turns informal sentences academic, the Paraphraser rewrites at three levels, and dedicated generators draft titles and abstracts based on your text or paper.

Writefull is used by students and researchers at more than 1,500 institutions and by major publishers and copyeditors, and it offers group and departmental licensing as well as premium access through institutional subscriptions. On privacy, the company states that texts and searches are processed over an encrypted connection and are never stored or used for training. It is available as a freemium product with paid and enterprise tiers.

**Pricing & Plans:** Writefull is sold as a freemium product: core features can be tried for free, while the full writing and proofreading toolkit requires a paid subscription. Institutional, group, and departmental licenses are available, along with premium access for universities and publishers and an enterprise offer. Exact pricing is provided on the vendor's site and via quote and may change.

- **Writefull for Word:** Get in-context language feedback automatically inside Microsoft Word, with options to paraphrase, change style, explain, or summarize text.
- **Writefull for Overleaf and TeXGPT:** Receive language feedback directly within your LaTeX code in Overleaf, generate LaTeX automatically, and use TeXGPT for tables, formulas, and equations.
- **Writefull Revise:** Upload a document before submission to see its overall language quality and apply corrections with Track Changes.
- **AI writing widgets:** Academizer turns informal sentences academic, the Paraphraser offers rewrites at three levels, and generators draft titles and abstracts from your text.
- **Citation support:** Writefull Cite helps you add and manage citations, rounding out a toolkit built for the academic publishing workflow.

**Strengths:** Language feedback specifically calibrated for academic writing; Integrates directly into Word and Overleaf workflows; Widgets for paraphrasing, academicizing, and generating titles and abstracts; TeXGPT automates LaTeX authoring for tables and equations

**Limitations:** Focused on academic English, so less suited to casual or marketing writing; Full premium features require a paid subscription or institutional access; Works best inside Word or Overleaf, so plain-text workflows are less covered; Non-English source support is limited compared to general proofreaders
