+
+I [mentioned a while ago](/post/filtering-podcast-feeds) that I wanted a way to filter Podcasts into multiple separate feeds based on their content. The tool I mention in the previous post, [SiftRSS](https://www.siftrss.com) is pretty good, but the only thing it doesn't currently do is let you change the name of the feed, which means I end up with several feeds with identical names.
+
+So, I made my own: [Baleen](https://git.lewisdale.dev/lewis/baleen). It's pretty simple, and it's a hobby project so the UX sucks - it's _just_ usable enough to be functional, but also that's because I wrote it. I'll hopefully make some changes in the future, but no promises.
+
+How it works is fairly simple. I can register a feed and a set of filters using the CLI:
+
+```bash
+php bin/doctrine test:feed -f include -t title -a "Something" <feed url> "New feed title"
+```
+
+This creates a new RSS feed, called "New feed title", which only includes posts from the feed URL that include the title "Something". I could also exclude certain titles with `-f exclude`, for example.
+
+Filtering is excruciatingly simple. It's just using XPaths on the target elements, joined by a pipe - so multiple filters work as an `OR`, not an `AND`.
+
+Anyway, this was a fun little project to create that solves a very specific problem.
