I have a very basic "content repository" that started out as an RSS reader and now has pocket/instapaper like link saving, notetaking and basic GPT integrations (summary for rss entries/saved links + chatgpt like interface since it's now blocked in italy and it sounded fun to reimplement it).
It's been fun having a project where i can just throw in stuff i want to learn (started out as a go + go templates app, then turned into go backend + vue frontend from scratch, now go + vue with vuetify) and where i can just implement features i want (pocket import for saved links, gpt stuff, linking between notes and saved links/rss entries, ...) that are extremely specific to my use case and thus hard to find in anything else.
