Overview
ACE–Step is an AI-driven music generation platform and open-source foundation model that converts text or voice prompts into complete, royalty-free songs. It combines a browser-first consumer product (acestep.io) with an open-source foundation model (ACE-Step on GitHub/Hugging Face) designed for speed, coherence, and controllability. The hosted service emphasizes rapid, mood-driven workflows for creators (e.g., “sad lo-fi”, “upbeat pop”), while the open-source model enables researchers and developers to run or fine-tune locally and integrate with tools like ComfyUI and Hugging Face Spaces. ACE–Step supports lyric generation and editing, voice cloning, lyric-to-vocal transformations, batch processing, and exports in MP3/WAV formats — making it suitable for social video creators, studios, educators, and agencies.
