Hypertextopia is a space where you can read and write stories for the internet. On the surface, it looks like a mind-map, but it embeds a word-processor, and allows you to publish your stories like a blog. It's designed to facilitate the writing of axial hypertexts by making a distinction between the fragments (essential elements) and the shards (minor, but enriching elements) of a story. You write in Hypertextopia by dragging the fragment arrow (the large one) or the shard arrow (the small one) and dropping them onto other fragments and shards, or onto empty space.

Kayuda is a web-based visual wiki, a mind-mapping tool, and a non-linear writing tool that allows you to track ideas and the relationships between them. It's free, and any number of people can collaborate simultaneously in real-time. You can have any number of "wikis" (called "workspaces"), and you can choose how private to make them.
