MEDIA PREVIEW
Live Negotiation Copilot. Demonstration video analyzing overseas sales meetings with dynamic strategy card generation.
Overview & Result
Masahiro Chaen built an app that listens to overseas sales meetings every 4 seconds, using Whisper for transcription and Jev for sub-50ms tactical objection classification and response card triggering.
How Jev fits in the loop
- Ingest live audio chunks continuously without blocking audio capture.
- Transcribe and translate dialogue into structured candidate debate points.
- Jev evaluates client intent, purchase friction, and next objection strategy in 45ms.
- Display contextual battle cards instantly on the representative's screen.
How to reproduce
- Review video showing live English negotiation transcribed and analyzed every 4 seconds.
- Pass extracted dialogue turns to Jev Choice to select objection counter-strategies.
- Surface matching visual response cards to the sales representative on screen.
Why this build matters
Brings real-time AI assistance into live interpersonal conversation where multi-second LLM generation is completely unusable.
Limitations
- Requires low-latency speech-to-text pipeline (Whisper / Deepgram).
- Limited to predefined tactical cards; novel negotiations need human judgment.
- Author reported community project.
