# Moss

Moss is building the real-time semantic search runtime for conversational and multimodal AI. Our system enables voice agents, copilots, and chat interfaces to retrieve, reason, and respond in sub-10 ms, delivering the responsiveness that makes AI interactions feel truly natural. If you’ve ever built a conversational or voice AI product, you’ve felt the lag. That moment when an agent pauses and the illusion of intelligence breaks. The bottleneck is almost always retrieval. Each query hops across

[### Conntour match 69Conntour enables organizations to query thousands of security cameras using natural language. Users can search past footage (“Find a man with tattoos on his left arm”), configure real-time alerts (“Notify me if someone climbs over the wall”), and extract data (“How many pickup trucks entered yesterday?”). Unlike traditional video analytics limited to pre-defined parameters (like a weapon, bag, or license plate), Conntour supports unlimited, highly specific scenarios described in plain language. shared extracted concept terms: real, time; shared product terms: enable, query, natural, search; shared affiliation: Y Combinator](https://highsignal.app/case-studies/conntour)[### Autumn AI match 61Autumn is building the first real-time signal intelligence platform for GTM teams.
