What is Harmonica?

Harmonica is an open-source platform for AI-facilitated group deliberation. Deploy it on your own infrastructure with your choice of LLM—whether self-hosted (Ollama, vLLM) or cloud providers (OpenAI, Anthropic, Google).

Instead of scattered feedback forms or unproductive meetings, participants engage in AI-facilitated conversations that surface the *why* behind their perspectives.

**How it works:**

1. Create a session with your discussion topic
2. Share the link with participants
3. Analyze the AI-generated synthesis with themes, priorities, and recommendations

Each participant has a private conversation with a custom AI facilitator. Harmonica then synthesizes all perspectives into actionable insights—surfacing consensus, highlighting tensions, and recommending next steps.
