Symphonia

AI-powered expert consultation platform. Run structured Delphi-style rounds with any group of experts — Symphonia collects their responses, lets them see each other's thinking, and uses AI to synthesise consensus, surface minority views, and generate the next round of questions automatically.

Built by Axiotic AI.

Three commands from zero to running:

git clone https://github.com/ruaridhmon/symphonia && cd symphonia
cp .env.example .env          # add your OPENROUTER_API_KEY
docker-compose up --build

Open http://localhost:3000 — log in with the admin credentials you set in .env.

Need an OpenRouter key? Get one at openrouter.ai/keys. The default model is Claude Sonnet 4.

Delphi methodology

• Multi-round structured consultation — each round builds on the last
• Real-time presence indicators (see who's online)
• Follow-up questions auto-generated from the previous round's synthesis

AI synthesis engine

• Built-in open-source simple synthesis with OpenRouter
• Optional advanced consensus engine for committee synthesis and diffusion-based iterative refinement
• Convergence scoring — know when experts actually agree

Rich analysis

• Minority Report — surfaces views the majority missed
• Devil's Advocate — strongest counterarguments to consensus
• Emergence Highlights — novel ideas that appeared across rounds
• Consensus Heatmap — visual agreement map across expert pool
• Cross Matrix — find where experts agree/disagree on each claim
• Voice Mirroring — rephrase synthesis in each expert's own style
• Audience Translation — rewrite for different audiences (policymakers, public, etc.)

Admin tools

• Form editor with multi-question support and custom expert labels
• Expert labelling presets: temporal, methodological, stakeholder, custom
• Synthesis version history with diff view
• Export synthesis as DOCX
• Audit log for all admin actions

Security

• CSRF protection (double-submit cookie)
• httpOnly session cookies + JWT
• Security response headers
• Cloudflare Access compatible

All configuration lives in a single .env file at the project root.

cp .env.example .env

See docs/INSTALLATION.md for the full configuration reference and non-Docker setup.

The default install is token-free and works from a public clone. It does not install the private axiotic-ai/consensus package.

If you have access to that repository and want the advanced TTD/committee modes, install:

cd backend
pip install -r requirements-consensus.txt
