I'm working on a better frontend (in sveltekit) for Udio - music generation app. Udio has good models to generate audio, but awful UI and organization/management tools. My frontend allows collecting all the generated content from udio, organize them by topic, rate them with 5-star rating system, add custom labels, filter by these, make playlists, generate prompts and create an arbitrarily long generate queue (udio allows you to create 4 prompts simultaneously so you can sit in front of UI babysitting it if you don't have custom tooling and you want to actually use your 4800 credits you paid for). I use LLMs heavily here, so the quality of code is so-so, but work very well for me and I'm having a lot of fun with this.
