FreshRSS is a self-hosted RSS and Atom feed aggregator.
In my experience, it has been great for staying updated on news and managing a significant portion of my social media, including video sharing platforms like PeerTube, Odysee etc :-)

FreshRSS can be extended with plugins. Maybe there is (or will be) a plugin to use language models and summarize texts.
