Overtone Meeting Assistant
Overtone is VisionsCraft's autonomous presentation agent: it joins Google Meet, Zoom, or Teams, renders the client's deck as camera output, narrates slides, and answers live questions only from deck content—with sub-3s spoken responses in a live Q&A loop.
The problem
Sales and enablement teams burn hours presenting the same deck and still struggle to answer questions accurately without going off-script or hallucinating claims.
The solution
A multi-platform meeting bot with hybrid retrieval over slides, grounded speaking rules, and a speech-to-speech path fast enough for a live room.
Overtone is an autonomous presentation agent that joins Google Meet, Zoom, or Teams as a real participant. It renders the client's deck as camera output, narrates each slide, and answers live questions only from slide content — no off-deck hallucination. A speech-to-speech path keeps response times tight enough for a live room.
Implementation
Hybrid retrieval across slide text, titles, and pre-generated Q&A; grounded speaking rules; filler audio while search runs; multi-platform meeting bots.

FAQ
Which meeting platforms does Overtone support?
Overtone joins Google Meet, Zoom, and Microsoft Teams as a real participant so it can present and answer questions in the same room as humans.
Does the agent invent answers not on the slides?
No. Speaking rules ground answers in slide content and pre-generated Q&A derived from the deck, reducing off-deck hallucination.
How fast are spoken answers?
The production loop targets sub-3 second spoken responses using retrieval plus a speech-to-speech path designed for live meetings.
