I'm the creator of MuseGen. Like many here, I've been experimenting heavily with generative AI. My workflow quickly became a mess of browser tabs: one for music, another for images, a third for video, each with its own UI, credit system, and quirks. The context switching was killing my creative flow.

My goal was to build a clean, unified front-end for a curated set of high-quality generative models, allowing a user to go from idea to a multimedia concept within a single session.

MuseGen is my first pass at solving this.

Here's what it can do:

AI Music: Generates full, high-fidelity songs (with vocals) or instrumentals from a text prompt. I've integrated a best-in-class model to ensure the output quality is top-tier.

AI Video: Creates short, coherent video clips from text. The backend uses a state-of-the-art model focused on maintaining visual consistency.

AI Image: Access to multiple models, with options optimized for different needs, like creative style or character consistency.

AI Lyrics: A utility to quickly generate lyrical ideas, verses, and hooks to overcome writer's block.

The frontend is built with React/Next.js, and the backend is a Node.js server that orchestrates calls to the various third-party APIs. One of the more interesting challenges was designing a normalized credit system to abstract away the different pricing and usage metrics of each underlying model (e.g., per-second of video vs. per-image). Roadmap:

The long-term vision is to build an "agent" layer on top of this. I want to enable a single, high-level prompt (e.g., "create a cinematic trailer for a sci-fi movie") to automatically generate and assemble the video scenes, a fitting musical score, and a script. I'm also constantly evaluating and swapping in new and improved models as they become available.

I would be incredibly grateful for any feedback, critiques, or technical questions from the HN community. I'll be here all day. Thanks for checking it out.
