Composer vs Ramble

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.

Ramble is a web-based collaborative Markdown editor with real-time team editing and an optional AI assistant. The editor shows Markdown source beside a rendered preview and supports formatting shortcuts, paste-to-Markdown conversion, find and replace, and Markdown export. Multiple people can edit together with live cursors, automatic saving, and merged changes after reconnecting. Already-open drafts can be edited offline with browser-local recovery, but loading Ramble or opening new pages needs a network connection. The assistant can answer draft questions, suggest edits for review, or create drafts from conversation. Workspaces support owner, editor, and viewer roles, plus read-only and revocable links. The Open plan costs nothing, but new accounts and invitations are currently closed.
