The AI conference companion that eliminates hallucination — every answer sourced, cited, and token-optimised.
Built for the Progress × GitNation Hackathon · JSNation + React Summit Amsterdam 2026
Generic chatbots hallucinate conference details — wrong speaker, wrong time, wrong room. ConferenceMap is not a chatbot wrapper, it's a verification layer. SigMap pre-filters the entire conference corpus to only the relevant chunks before any token reaches Gemini, then verifies every factual claim in the answer against those chunks. The whole pipeline is transparent: input tokens, output tokens, latency, cost, citations, and a faithfulness score are shown live on every reply.
| ~60–97% | input-token reduction by SigMap (scales with corpus size) |
| 0.3–2s | first-token latency (Gemini 2.5 Flash, streaming) |
| 100% | of factual claims cited and verified post-generation |
| 0 | hallucinations — the model declines when context is missing |
- Ask — conversational Q&A with verified, cited answers, a live trust panel, and smart follow-up suggestions
- Sessions — KendoReact Grid with natural-language AI filtering
- Agenda — personal time-blocked schedule
- Organiser — engagement analytics + coverage-gap detection
- For Judges — a built-in

A single Next.js 15 process — no separate API server, no vector DB. The TF-IDF index lives in module memory, built once at cold start and reused per request. Full detail in ARCHITECTURE.md.
