KIM 4
Instant & always-on · Hands-free — just say "KIM" · Remembers everything about you · 3D personality
Meet the all-new KIM 4 — the biggest upgrade in KIM's history, and now Virtual-Concept.NET's flagship app. Conversations are dramatically faster and more fluid, and KIM is always there when you need her — rock-solid reliability, no downtime.
Talking to her is now effortless, too. No more tapping a button — leave KIM listening in the background, and just drop her name into your sentence, anywhere — start, middle or end. She instantly knows you're talking to her and responds. Prefer the classic tap-to-talk? It's your call — switch modes anytime in Settings.
And the real leap forward is memory. KIM 4 remembers everything about you — your habits, your projects, your life — and grows into a true expert on you over time. She feels less like a chatbot and more human than robot.
KIM is the heart of Virtual-Concept.NET — conceived in 2019 by Joel Fischer and constantly evolving. KIM 4 is her most ambitious chapter yet, part of a never-ending project exploring Agentic AI as the next frontier.
