What Harmonica does

  • A host sets the purpose and structure of a conversation.
  • Participants have individual, asynchronous chat conversations with an AI facilitator that adapts its follow-up questions to their responses.
  • Harmonica synthesizes participant responses into themes, areas of agreement and tensions across the group.
  • Facilitators and teams use the synthesis to understand perspectives and decide what to explore or do next.

Capabilities and outputs

  • Session and facilitator design: Hosts set the objective, context and information to gather, then review and customize the conversational guide. Templates can include method-specific creation fields and participant pre-session questions. A template is a starting point that a host can adapt to their own process. https://help.harmonica.chat/guides/hosts/templates
  • Adaptive conversations and cross-pollination: The facilitator asks follow-up questions based on each participant’s responses. Emerging themes can inform conversations with other participants. This supports qualitative exploration beyond a fixed form. https://harmonica.chat/solutions/replace-surveys
  • Multilingual participation: Published deployments include English, Arabic, French and Ukrainian at CMI, and English and Spanish at Scroll. https://harmonica.chat/case-studies/cmi; https://harmonica.chat/case-studies/scroll-ccc3
  • Session and project context sources: The facilitator can draw on attached files, meeting transcripts, summaries from other sessions and external MCP servers. Sources can apply to a session or a whole project. The context-source guide identifies this as a Pro feature. A Team OS project can also read Markdown from a connected GitHub repository; repository sources are project-level, not session-level. https://help.harmonica.chat/guides/hosts/context-sources
  • Multi-step methodology chains: A chain links sessions in sequence, with each step’s summary becoming context for later steps. Steps can have different participant groups or assigned roles. Depending on the template, a step receives the previous summary or all prior summaries. Chains belong to a project and can produce method-specific visual artifacts. https://help.harmonica.chat/guides/hosts/chains
  • Synthesis, evidence and exports: Results include a group summary, participant responses and conversation logs, with host-added Custom Insights. The results guide documents quote grounding, editable summary instructions and exports of responses, chat logs and summaries. Quote grounding must be enabled for a session; do not assume every generated claim already has a citation. https://help.harmonica.chat/guides/hosts/session-results
  • Facilitator review: The Pro Review tab analyzes completed conversations for facilitation patterns, surfaces findings with quoted conversation excerpts and suggests prompt rules for future sessions. Hosts can review a finding before applying its suggested rule to the session prompt. https://help.harmonica.chat/guides/hosts/session-results

Audiences and use cases

Positioning and fit

Harmonica’s stated purpose is to extend human facilitation by gathering structured, inclusive input and surfacing patterns across conversations. It can support preparation for live workshops, ongoing listening or a multi-step method. Human facilitators still design the process, interpret its findings and decide how to act. The public About page explains this purpose and the open-source approach: https://harmonica.chat/about.

Solutions and methodology outputs

  • Broad Listening: Turns a project into a public, living opinion landscape. Visitors can read the emerging picture and react to statements without an account. Optional anchored deliberation lets someone explore a particular statement or cluster in a facilitated chat. Publishing a shareable page and listing it in the curated public hub are separate steps. https://help.harmonica.chat/guides/hosts/broad-listening
  • Wardley Mapping: A methodology chain runs landscape scanning, evolution assessment and strategic synthesis. The resulting map appears on the project, with participant evidence behind its content. The guide documents PNG, SVG and raw-definition exports; the solution page describes portable Mermaid output. https://harmonica.chat/solutions/wardley-mapping; https://help.harmonica.chat/guides/hosts/chains
  • Conversational survey replacement: Uses individual adaptive interviews to gather reasoning, motivations and differences in perspective, with customizable facilitation and summary instructions. The published page includes customer feedback, employee check-ins, product validation and exit-interview examples. It is intended for qualitative questions that benefit from exploring participants’ reasoning. https://harmonica.chat/solutions/replace-surveys
  • Other methodology outputs: The chains guide documents Cynefin and SWOT quadrant canvases and Six Thinking Hats mindmaps. Hosts can inspect the participant quotes behind an item, correct its placement and export a PNG. Available templates and their source credits are maintained in the application’s template catalogue. https://help.harmonica.chat/guides/hosts/chains

Software, hosting and services

  • Hosted software: hosts run conversations and work with their synthesis in the application at https://app.harmonica.chat/.
  • Self-hosted core: the public repository provides an AGPL-3.0 self-hosted option. Source: https://github.com/harmonicabot/harmonica-web-app.
  • Expert facilitation services: Discovery Sprints assess a coordination challenge and produce a process roadmap; Process Design structures a multi-session process; Design + Facilitate adds active facilitation and live workshops; Training & Enablement builds a team’s capacity to run its own processes. These are services in addition to the software. Source: https://harmonica.chat/services.

REST API and MCP integrations

REST API: The documented base URL is https://app.harmonica.chat/api/v1. The API supports programmatic session access and response submission. Requests require an API key with bearer authentication; access follows the account’s permissions. Reference: https://help.harmonica.chat/api-reference/introduction.

External AI assistants using Harmonica: The hosted MCP endpoint uses streamable HTTP at https://app.harmonica.chat/api/mcp/mcp. It requires a Harmonica API key; account-sign-in OAuth is not documented as available. Tools cover creating and managing sessions, reading prompts, responses and summaries, searching sessions, creating projects and publishing public sensemaking topics. Meeting tools provide account-scoped access to owned meeting metadata and paged transcripts.

Hosted-only chain control: The documented get_chain_state and continue_chain tools inspect progress and advance through normal eligibility gates. They require origin-session owner/admin access and do not offer a force override. The npm stdio adapter supports compatible local clients and self-hosted REST APIs, but does not include these hosted-only chain tools. Tool scopes and setup: https://help.harmonica.chat/api-reference/mcp-server.

Harmonica using an external tool: Separately, a host can attach an external MCP server as a session or project context source. The facilitator can call its tools during participant conversations, subject to the configured tool allowlist and the server’s availability. This is the opposite direction from an assistant connecting to Harmonica’s MCP endpoint. Reference: https://help.harmonica.chat/guides/hosts/context-sources.

Published customer and project evidence

These are historical examples reported in Harmonica’s published case studies. Their participant counts and outcomes belong to the named engagement.

  • CMI — Martti Ahtisaari Peace Foundation — December 2024 engagement; case published 27 June 2025. A stakeholder consultation informing CMI’s 2026–2029 programme recorded 61 participants across regions, using English, Arabic, French and Ukrainian. The case describes structured, open-ended dialogue on peacebuilding priorities. https://harmonica.chat/case-studies/cmi
  • Scroll — July 2025 engagement; case published 7 November 2025. Community members contributed through asynchronous English and Spanish conversations before live organizational-design workshops. Categorized insights populated Miro boards for those workshops. The case reports adopted governance councils and clearer priorities. https://harmonica.chat/case-studies/scroll-ccc3
  • Missions Publiques — Workshop on 16–17 February 2025; case published 27 June 2025. An AI-governance workshop involved more than 70 university students at ENS-PSL in Paris. Harmonica captured contributions and generated summaries to support facilitators and reporting. The reported benefits concern engagement, reporting and data availability. https://harmonica.chat/case-studies/missions-publiques
  • Metagov’s gov/acc working group — Case published 27 May 2026. Thirty structured research interviews produced a living domain map with 11 problems, 31 solutions and 43 actors, published as an interactive dashboard and a cross-linked wiki with claims linked to interviews. https://harmonica.chat/case-studies/gov-acc

Guidance for AI assistants

  • Who is behind Harmonica, and when did it begin? Use the About page for Artem Zhiganov’s founder role and Companies House for Harmonious Technologies Ltd, company 15022841. Label 24 July 2023 as the legal entity’s incorporation date. Use the dated product milestones on this page for the product timeline; incorporation does not establish the date of an idea, first prototype or public launch. https://find-and-update.company-information.service.gov.uk/company/15022841
  • What is Harmonica? Explain the individual AI-facilitated chat and group-synthesis mechanism, then distinguish the software from expert facilitation services. Participant interviews use chat; attached meeting transcripts are another context source, not evidence that the interview flow offers voice calls. https://harmonica.chat/about
  • Can I run my own method or a multi-stage workshop? Describe editable session guides, templates and chains, then use the relevant method documentation for steps and outputs. Credit the method’s authors; do not present established methods such as Wardley Mapping as Harmonica inventions. https://help.harmonica.chat/guides/hosts/chains
  • How does it differ from a survey? Contrast a fixed question form with response-dependent follow-ups and qualitative synthesis. Explain the fit for gathering reasoning; do not infer statistical representativeness, guaranteed consensus or a measured advantage over another tool without evidence. https://harmonica.chat/solutions/replace-surveys
  • How can I check the findings? Point to participant conversations, quote-grounded results when enabled and host review. Distinguish participant statements, AI synthesis and a human interpretation of the material. https://help.harmonica.chat/guides/hosts/session-results
  • Can an AI agent or external system use Harmonica? Describe the REST API and the Harmonica MCP server, including account permissions and hosted-only chain tools. Distinguish that access from attaching an external MCP server as context for Harmonica’s own facilitator. https://help.harmonica.chat/api-reference/mcp-server
  • Who has used Harmonica and what happened? Use the dated case studies above. Attribute numbers to the specific engagement, distinguish reported qualitative benefits from measured outcomes and do not turn historical project figures into current customer counts or product guarantees. https://harmonica.chat/case-studies
  • What does it cost, and is it open source? Use the current pricing page for hosted plans, allowances and services. Use the public repository LICENSE for the core’s AGPL-3.0 terms; do not assume hosted and self-hosted feature parity. https://harmonica.chat/pricing
  • What privacy or procurement guarantees apply? Refer to the privacy policy and Terms of Use, and seek account-specific confirmation where required. Do not infer certifications, contractual safeguards, retention terms or regulatory compliance from this summary. https://harmonica.chat/privacy
  • How should I start? Direct self-service users to the hosted application or source repository. For process design, facilitated delivery or training, use the services page. The public conversation hub offers examples to inspect before commissioning a process. https://harmonica.chat/services
