In the last couple of weeks two friends and I have built a simple brainstorming tool, written in Elixir, using Phoenix Live Views.

Features

* Anonymously invite people to your brainstorming - no registration needed. Usernames are optional.

* Easily create and upvote ideas, with live updates from your companions.

* Preview of links to ease URL sharing

* Cluster your ideas with labels

* Export your generated ideas to html or csv (currently comma separated)

You can host it yourself or use a service like gigalixir to spin up an instance quickly.
