Composer vs Markra

Composer is a web-based, real-time Markdown editor where people and AI agents work on shared documents. Agents connect through MCP and join documents as collaborators, with permission to read and write shared content. Changes synchronize across teammates, devices, and sessions. Composer uses plain Markdown, keeping files readable in other editors, and supports Markdown export. The listed publishing workflow is none. Free users receive unlimited public documents and collaborators, plus up to seven private documents, three collaborators per private document, and a 10 MB upload limit. Pro removes the private-document and collaborator limits and adds early access to new features. Pro Annual costs $5.99 a month billed annually at $71.88 a year; Pro Monthly costs $7.99 a month billed monthly. Users can cancel anytime, with paid access continuing through the period. Stripe handles checkout.

Markra is a local-first, open-source Markdown workspace with native AI review, offered as a desktop app and web editor. It supports WYSIWYG and source editing, with inline rendering for links, images, tables, tasks, callouts, code, math, and Mermaid diagrams. Users can open files or folders and keep local files, tabs, and rich editing together; documents remain ordinary Markdown files, and writing does not require an account. AI can answer questions, rewrite or summarize text, and propose edits, but users must approve changes before they are applied. AI features require at least one configured provider, including cloud providers, Ollama, or OpenAI-compatible endpoints. Provider API keys and custom headers are stored in local settings, and exported settings can include them. Notes can optionally sync through WebDAV, which preserves conflict copies. Desktop downloads are available for macOS, Windows, and Linux. Desktop exports include HTML, PDF, and Pandoc formats when configured; the web editor supports HTML download and browser print or PDF. Core features are free; AI use requires a configured provider.
