Underleaf VS Eddyter

Underleaf's answer

Underleaf is built specifically for people who write in LaTeX. Unlike generic AI writing tools, it understands mathematical structure, equations, and academic formatting. It can convert PDFs and handwritten notes directly into clean LaTeX, generate TikZ diagrams, and help refine technical writing - all while preserving document structure. It’s designed to feel like a natural extension of your LaTeX workflow, not a replacement for it.

Eddyter's answer:

Eddyter is an AI-native rich text editor that ships as a single npm package and is fully managed. Most editors give you a framework and leave hosting, file storage, scaling and AI wiring to you. Eddyter includes all of that.

• Integrate in 10 minutes: install the package, add your API key, and render the editor
• AI built in: AI chat and slash commands inside the editor, with a choice of bringing your own LLM key (BYOK) or using fully managed AI
• Managed infrastructure: image and file storage, hosting and scaling are included, so there is no backend to build
• Built on Meta's Lexical: a modern, fast and extensible foundation
• Framework coverage: React, Next.js, Vue, Angular, Svelte, Vanilla JS and Laravel
• MCP server: AI coding agents can add Eddyter to a project through the eddyter-mcp package

Underleaf's answer

Most tools treat LaTeX as plain text. Underleaf treats it as a first-class language. It’s purpose-built for researchers, students, and technical professionals who care about correctness, structure, and reproducibility. With deep support for equations, diagrams, and academic formatting - plus seamless Overleaf integration - Underleaf saves hours without compromising precision or control.

Eddyter's answer:

Compared with TinyMCE, CKEditor, Tiptap, Quill and Slate, Eddyter removes most of the work that usually comes with adding an editor to a product:

• Faster integration: a working editor in about 10 minutes instead of days of toolbar, plugin and upload wiring
• AI included, not a paid extension: AI features are part of the AI plans rather than separately priced add-ons
• No infrastructure to manage: storage, hosting and AI processing are handled for you
• Lower cost: paid plans start well below the published prices of comparable commercial editors
• Modern architecture: built on Lexical with TypeScript, designed for current React and Next.js apps
• Free tier: start without a credit card and upgrade when you need white-label or AI features

Underleaf's answer

Underleaf is built for professors, researchers, graduate students, and technical professionals who regularly write in LaTeX. This includes people in mathematics, physics, engineering, computer science, and related fields who want to move faster without sacrificing rigor or formatting quality.

Eddyter's answer:

Eddyter is built for developers and product teams who need a rich text editor inside their own application:

• React and Next.js developers building SaaS products
• SaaS founders and startup teams who want to ship editing and AI writing features without building them from scratch
• Product teams adding content creation to dashboards, CMSs, help centers, internal tools and user-generated content features
• Agencies that build client projects and need a dependable editor they can reuse across them

Underleaf's answer

Underleaf was created out of firsthand frustration with how slow and manual academic writing can be. After years of writing papers, notes, and technical documents in LaTeX, the goal became clear: remove the friction without breaking the workflow researchers rely on. Underleaf started as a personal productivity tool and grew into a platform that helps thousands of academics write faster, cleaner, and with more focus on ideas instead of syntax.

Eddyter's answer:

Eddyter started from a problem our founder, Nimish, kept running into. He built the same rich text editor at three different jobs, on Lexical, Slate and ProseMirror. Each time it was the same wiring: toolbar, formatting, file uploads. Then someone would ask to "add AI," and the project would double in scope.

After the third time, we decided to turn it into a product. Eddyter is the editor we wished we had at every previous job: drop it in, get AI included, and integrate it in 10 minutes. It is built by Craxinno Technologies in Jaipur, India, and launched publicly in March 2026.

Eddyter's answer:

• Lexical (Meta's editor framework) as the core editing engine
• React and TypeScript
• Next.js for the web platform and dashboard
• Tailwind CSS and shadcn/ui for the interface
• Supabase for the database and authentication
• Redis for subscription and license sync
• Stripe for billing
• LLM integrations (bring-your-own-key or managed) for AI features
• Framework packages for Vue, Angular, Svelte and Vanilla JS, plus a Laravel package on Packagist
• Model Context Protocol (MCP) server for AI coding agent integration

Eddyter's answer:

• SaaS startups embedding AI writing features into their products
• Independent developers building React and Next.js applications
• Software agencies using Eddyter across client projects
