Find common ground in your community
Chorus is an open-source tool for collecting opinions and finding consensus at scale.
How it works
Chorus implements a pol.is-style process: collect statements, let people vote, and then see where groups who think differently about the topic agree.
Collect statements
People submit short statements about a topic.
Vote
People vote agree, disagree, or pass on each other's statements. No threading, no replies.
See the shape of opinion
Groups of similar opinions emerge. See where these groups differ, and where they find common ground.
Get involved
Chorus is actively developed on a fully volunteer basis. Contributions are welcome — whether that's code, design, documentation, or feedback.
