I built an interactive stream overlay tool designed to run completely locally: AskAvatar 5.0.
Instead of static alerts, viewer tips & subs trigger reactive on-screen avatars with real-time AI voice replies.
Key focus was privacy and zero recurring costs: it runs directly on your machine via Ollama, so there are no cloud API fees or monthly subscriptions. Drops straight into OBS as a transparent window capture.
