Koi

Koi is an AI assistant application that dictates text, records calls, transcribes files, and manages documents and schedules on Mac.

Koi is a productivity application for Mac that provides offline dictation in 100 languages and acts as an assistant that sees your screen, answers questions, and executes actions. Users can dictate text into any application, record calls, transcribe files, track expenses, manage documents with tables and flashcards, and organize Google and Apple calendars in one weekly view. The app operates locally on the Mac for dictation and file storage while offering AI features for complex questions, web searches, and screen interactions. It supports seven voice models including Parakeet, Whisper, Qwen, Cohere, and Granite. The interface uses keyboard shortcuts and a shift wheel for file actions like compression and conversion.
