Marcko V2 is an open-source markdown editor built for developers, technical writers, startups, and AI-native teams that want a fast, modern, and secure writing experience. Designed for high-speed documentation workflows, Marcko combines real-time markdown editing, enterprise-grade sharing controls, and AI-connected publishing into a single platform.

Unlike traditional markdown editors that focus only on writing, Marcko is built around the full lifecycle of technical content creation. Users can draft notes, changelogs, blogs, product documentation, internal knowledge bases, launch announcements, and developer guides while maintaining complete control over security and visibility.

Marcko V2 supports GitHub Flavoured Markdown (GFM), syntax highlighting, Mermaid diagrams, KaTeX math rendering, tables, task lists, and raw HTML rendering. The editor provides an instant live preview experience so users can write and format documents without interrupting their workflow.

One of the biggest additions in Marcko V2 is native MCP publishing support for modern AI workflows. Users can create or refine content directly inside AI tools like ChatGPT, Claude, Cursor, Windsurf, Continue, Cline, and Zed, then publish instantly into Marcko without copy-paste or formatting issues. This makes Marcko one of the first markdown platforms designed specifically for AI-assisted documentation and content pipelines.

Security is a core part of the platform. Shared documents are encrypted at rest, only authenticated users can generate public links, and creators can track, reopen, or revoke links at any time. Marcko is designed for teams that need the speed of lightweight documentation tools without sacrificing governance or operational control.

Marcko V2 also includes embeddable feedback widgets that allow teams to collect structured feedback, ratings, and responses directly from readers using lightweight scripts. This makes it useful not only for writing documentation, but also for gathering insights from users, teammates, and customers.

Whether you are building technical documentation, developer tools, AI workflows, startup launch content, or internal team knowledge systems, Marcko V2 provides a modern markdown experience focused on speed, security, AI integration, and seamless publishing.
