Polis
activeOpen-source AI-assisted deliberation platform using ML clustering to map opinion landscapes. Participants submit brief statements and vote agree/disagree/pass; algorithms cluster similar voters and surface bridging consensus. No reply button (eliminates trolling). Deployed in dozens of countries across five continents. vTaiwan: 26+ issues, 80% implementation rate. Anthropic CCAI: ~1,000 participants contributed to training Claude's constitution.
Organizations
2| Computational Democracy Project | Nonprofit stewarding Polis, the open-source AI-assisted deliberation platform used in 35+ countries. Co-founded by Colin Megill. Polis uses ML clustering to map opinion landscapes, surface consensus, and bridge divides. Used by Taiwan's vTaiwan for 26 national issues (80% implementation rate) and by Anthropic for Collective Constitutional AI. |
| Olas (Autonolas) | Protocol for building and coordinating autonomous multi-agent systems across blockchains. Uses Tendermint consensus so multiple agents must agree before executing on-chain. Decentralized marketplace for AI agent services. |

3| Habermas Machine | Google DeepMind's LLM-based "caucus mediator" trained to generate group opinion statements identifying areas of agreement on complex political/social issues. Published in Science (October 2024). Tested on 5,700+ UK participants. AI-mediated statements consistently preferred over human-written ones for quality, clarity, and perceived fairness. |
| Talk to the City | Open-source LLM tool for scaling deliberation. Analyzes large-scale public input (surveys, interviews, social media), clusters opinions using semantic analysis, and creates interactive navigable opinion maps. Deployed in Taiwan (moda ministry), Chatham House "Recursive Public" project (1,000 participants), Tokyo election polling, UNFCCC climate negotiations. Audrey Tang says it reduces "broad-listening" cost to "essentially zero." |
| Deliberation.io | Open-source platform from Stanford HAI's Digital Economy Lab and MIT GOV/LAB using Socratic dialogue for large-scale AI-assisted deliberation. Four components: individual engagement, AI agent interaction, "Face of the Crowd" opinion distribution, "Dynamic Deliberation." First US city deployment: Washington DC (July 2025). |
