## GranthOS

GranthOS targets the friction that makes LaTeX painful for students and researchers: broken builds from a stray backslash, nights spent fixing margins and citations, and equations that are hard to get right. Because it runs in the browser, there is no local TeX distribution to install or maintain, and compilation is fast enough that previews update almost as you type. The AI layer is the differentiator: instead of being a plain typing-and-compile surface, GranthOS can draft a section from an outline, expand or polish prose, turn a described equation into correct LaTeX, and render a diagram as TikZ or PGFPlots code.

Beyond the editor, GranthOS bundles a large library of academic assets. The template collection covers research papers, PhD theses, Beamer presentations, academic CVs, cover letters, lab reports, question papers, answer keys, rubrics, schema and conference formats such as NeurIPS and ICML. A companion tools site adds converters — Math to LaTeX, Excel to table, Image to TikZ, Markdown and MathML conversion, a LaTeX preview and a citation generator — plus an extensive symbol reference organised into dozens of categories. Question paper and answer key generation from a prompt is a notable focus for educators who build exam variants.

The product is positioned explicitly as an Overleaf alternative and competes on an accessible free tier, a 14-day free trial with no credit card required, and an AI-first workflow. The site advertises a free plan, paid upgrades, and 100+ templates alongside a tutorial library for LaTeX, TikZ and PGFPlots. Pricing details are surfaced through a section on the homepage rather than a dedicated page, so exact plan tiers should be confirmed on the site itself.

**Pricing & Plans:** GranthOS advertises a free plan alongside paid upgrades and a 14-day free trial that requires no credit card. Exact tier limits are listed in the pricing section of the homepage rather than on a separate page.

- **AI drafting and refinement:** Generate document structure from an outline, expand sections and polish academic prose without leaving the editor.
- **Equations and TikZ from plain language:** Describe the formula or diagram you need and get working LaTeX, TikZ or PGFPlots code instead of hunting for syntax.
- **Fast in-browser compilation:** Compile and preview LaTeX directly in the browser with no local TeX installation to set up or maintain.
- **100+ academic templates:** Start from ready-made LaTeX for research papers, theses, Beamer slides, CVs, lab reports, question papers, answer keys and conference formats.
- **Converter and reference tools:** Math to LaTeX, Excel to table, Image to TikZ, Markdown/MathML conversion, citation generation and a symbol library in one place.

**Strengths:** AI is built into the editor rather than bolted on, covering prose, equations and diagrams; Runs fully in the browser with no local LaTeX installation; Large library of templates and converters, useful for papers, theses, exams and CVs; Free plan and a 14-day trial with no credit card required

**Limitations:** No dedicated pricing page; plan details live in the homepage section; Naming a well-known peer as its main comparison invites direct feature scrutiny; AI output still needs a careful academic review before submission

## 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
