HackMD

HackMD is a collaborative Markdown editor designed to facilitate real-time teamwork on documents. It offers a straightforward interface with a two-part layout, featuring an editor on one side and a live preview on the other. This setup allows users to see changes as they are made, enhancing the collaborative experience.

One of HackMD's key strengths is its ability to support multiple users working on a single document simultaneously. Each collaborator is assigned a unique color code, making it easy to track who is contributing what. This feature simplifies the process of editing and revising documents, reducing the need for multiple iterations and saving time.

HackMD is free to use and provides a solid set of features, making it an attractive option for those looking for a simple yet effective Markdown-based collaboration tool. Its focus on collaboration and ease of use makes it a suitable alternative to traditional word processors for teams working on documents together.
