Before Mimora I'd talk to the agent and then stare at a Discord text channel waiting for a response. No feedback loop at all. You say something and then... silence until text appears. Felt like talking into a void so I'd default back to the keyboard every time.
With the avatar there's a "listening" state when I'm speaking, a "thinking" animation while it processes, and expressions when it responds. It became this permanent little spot on my screen where I can glance and immediately see what the agent is up to. That alone was enough to make voice feel like an actual conversation instead of a command line with extra steps.
I've been doing game dev for years so building a 3D character with expressions was second nature. Made it easy to prototype fast and figure out where the real value was. Turns out it wasn't about making it look cool, it was just about closing that feedback gap between you and the agent.
