The Challenge
The problem we set out to solve.
Real estate agents were losing high-intent buying signals during calls because they lacked instant access to client history, budget and preferences mid-conversation. Valuable follow-up context was either missed entirely or scattered across disconnected notes, weakening conversion rates on tours and deals.
Our Approach
How we approached it.
The brief was time-sensitive: prompts had to surface during a live call, not after. We scoped a Flask + WebRTC architecture so transcription, intent recognition and CRM lookups could all run inline with the audio stream, with the AI prompt engine reasoning on each new utterance as it landed.
What We Built
The features that made it work.
We engineered a Flask and WebRTC-based platform integrated with OpenAI for real-time transcription and intent recognition, pulling live CRM data during active calls. The AI prompt engine analyses call flow as it happens and delivers exact next-step suggestions — tour bookings, follow-ups, objection handling — with every transcript securely saved for deal tracking and downstream analytics.
