Happy to introduce my first nostr project, https://github.com/atrifat/nostr-filter-relay , an aggregator filter relay which classify notes/posts into various category. This relay can be used mainly as "Global" relay in nostr clients, helping users to filter their global feed.

Currently, it has already several filtering features (also planned features listed):

- Language detection

- Not SFW or SFW image content detection

- User type filtering (Nostr non-bridged/regular user, activitypub/mostr pub bridged user)

- (Planned) Sentiment analysis

- (Planned) Topic classification

- (Planned) Hate speech detection

Feel free to check "USAGE" docs in Github for more information and examples on how to use the relay.

There is a public demo (beta/test) relay wss://nostr-id-relay.hf.space for those who can't run their own nostr-filter-relay software. Feel free to test the relay, although the performance is not always guaranteed, since this is only a test server.
