## Description

Polis is an open-source, AI-assisted sentiment-gathering platform from the Computational Democracy Project, built for running "conversations" with large groups: participants submit short statements and rate other people's statements as agree, disagree or pass, while a math engine sorts participants into opinion groups and surfaces statements that different groups agree on. Everyone in a conversation can watch the opinion landscape update as votes arrive, and the participation UI ships in a number of languages. Owners get an admin interface with moderation (approve, reject or leave comments unmoderated, in either a strict or a permissive scheme) plus a live report they can share by link; conversations can be dropped into your own pages with an embed code. A Python service (delphi, together with the math-python poller) does the clustering math and can produce topic names and narrative reports through Anthropic's API or a local Ollama model, while Google-based comment translation and Akismet spam filtering are switched on with API keys. Self-hosting means Docker Compose from the repo — Node.js API server, static web clients, Postgres, an nginx proxy and the Python analysis services — with separate docs for configuration, SSL and scaling; the project's own FAQ cautions that running your own instance is doable but still needs experienced cloud engineers, and the bundled self-signed certificate is meant for testing only. The hosted instance at pol.is is free for nonprofits and government.
