NarratoAI is an automated film and video narration tool that uses LLMs for script writing, automated editing, voice-over, and subtitle generation in a single workflow. It supports both a self-hosted open-source edition and a hosted cloud version. Download the package that matches your operating system and extract it completely; do not move the NarratoAI, runtime, or tools directories separately. Windows uses the x64 package, while Apple Silicon Macs use the arm64 build.

Recent README updates include optional Sonilo AI music, IndexTTS support for Apple Silicon, updated MLX/API integrations, improved local setup with uv and Python 3.12, cache cleanup, validation for OpenAI-compatible base URLs, API-key warnings, improved cross-platform subtitle and audio handling, updated Doubao TTS configuration, and other core workflow improvements.
