How do you implement auto-filters?

I made this as a minimal way to share one’s blocklists https://overmod.org/

I have a Chrome extension there but I also have an iOS app that I use for myself alone (it’s really not production grade). The Chrome extension is pretty rudimentary so if you want to replicate it you can just tell your agent to do so and if it helps the source is on GitHub. The iOS app is vibe-coded entirely so perhaps you’re better off starting from scratch there.

It’s a pretty basic requirement to interact with social media these days, I think because the information feed is full of noise.

Here’s another user who implemented a different approach: https://news.ycombinator.com/item?id=46459985
