MarkShare real-time Markdown collaboration

A lightweight collaborative layer for technical writers who live in Markdown

Problem

Developers who write technical docs in local Markdown editors like Typora lose the local feel and Markdown purity the moment they need real-time multi-user editing, comments, and review. They are forced into heavy online doc platforms.

Solution

A minimal Markdown editor with a real-time collaboration layer: multiple people edit the same file simultaneously, with comments, version history, and agent access for automated edits. Available as desktop and web, with local-first file storage.

Users

Individual developers, open-source maintainers, and small technical teams writing docs

MVP

Typora-like minimal editor; CRDT-based multi-user real-time editing; tables, code, LaTeX, Mermaid rendering; shareable read-only or editable links; local-first files with Git sync

Revenue

Free for individuals; team subscription per seat for collaboration spaces and permissions; or one-time desktop purchase with collaboration service subscription

Why now

Teams increasingly treat Markdown as the source of truth while AI agents start editing docs too; existing tools are either too local or too heavy, leaving room for a middle layer
