Questions & Answers

As answered by people managing Rectangle and Eddyter.

What makes your product unique?

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

Why should a person choose your product over its competitors?

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

How would you describe the primary audience of your product?

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

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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

Who are some of the biggest customers of your product?

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
