MimirAI is a private, always-on-top Windows assistant for live calls and conversations. It transcribes system audio and, optionally, your microphone, then turns the live context into concise answers, notes, follow-up questions, and practical guidance.
MimirAI is similar to Cluely but completely free and requires no subscription. It runs locally on your system but uses OpenAI's API for transcription & AI analysis.
MimirAI can be used for meetings, calls, and much more. The app has a full onboarding process teaching users how to use it.
