Harmonica gave our facilitators more space to focus on deeper engagement with participants. It made post-event reporting faster and more accurate than ever before.

FAQs

How can we help?

What is Harmonica?

Harmonica is an AI-facilitated structured conversation platform. It conducts 1-on-1 conversations with each participant using an AI facilitator, then synthesizes responses to surface themes, tensions, and consensus across the group.

How is this different from surveys or polls?

Surveys collect static answers. Harmonica has a conversation: the AI facilitator adapts to each response, asks follow-ups, and goes deeper. You get richer, more nuanced input than any form can capture. On Pro, cross-pollination shares emerging themes between participants in real time.

Will an AI facilitator be as good as a human?

Harmonica augments facilitators, it doesn't replace them. It handles the time-consuming parts (conducting individual interviews, synthesizing responses, tracking themes) so facilitators can focus on design, interpretation, and decision-making. The 1-on-1 format actually gets deeper responses than group settings, where social dynamics often silence quieter voices.

Is my data used to train AI models?

No, never. Your session data is stored in a secure database and is never used for AI model training. You can also use Bring Your Own Model (BYOM) to route conversations through your own API keys, or self-host the open-source version for full data control.

Can I customize the facilitation approach?

Yes. Choose from built-in templates (Retrospective, SWOT, Six Thinking Hats, and more) or write your own facilitation prompt. With BYOM, you can also choose which AI model powers your sessions: OpenAI, Anthropic, or Google.

Is Harmonica open source?

Yes. Harmonica is open core: the core platform is open source (AGPL-3.0) and can be self-hosted. The Pro cloud version adds cross-pollination, chain workflows, HARMONICA.md org context, public sharing, and managed bots.

Do participants need to install anything?

No. Participants just click a link and start talking: no account, no app, no install. Sessions work in any browser. Anonymous participation is supported by default.
