What's your weirdest or most unique self-hosted use case and solution?

I’m self hosting on an old laptop, and I’m a convert for life. Self-hosting is amazing. Looking for other people’s weirdest examples of what they’re doing as inspiration.

My example, I recently set up a grammar script, where I have a couple 8b LLMs and an html landing page. I upload a doc and it corrects grammar and highlights changes it made, or just proofreads and I make changes manually. I can upload a novel before bed, and have suggestions based on specific writing styles in the morning. All local, perfectly suited for my own work.

I used to use YouTube for music, specifically to watch and listen to music videos, but YouTube kept making that harder.

I use tube archivist to basically have my own jukebox. Dont have an account with YouTube and can have my own collection.

Wanted to have a streamlined system where I use invidious with custom download controls but YouTube makes invidious very fickle.

I have an Invidious instance going, and a boatload of MP3s from the last 30 years… Tell me more.

This way I have local MP4 files of all my favourite music videos. One day I would want to make software that organizes them as music (with artist info and all that)?and somehow gets the equivalent MP3 files for them as well, but for now it’s just an app that has over 1000 music videos that I play in the background.
