About ants
ants is a search and discovery interface for Nostr notes and text. It supports keyword search with modifiers for authors, hashtags, media, content types, and dates, and opens profiles, events, and hashtags from NIP-19 identifiers and related URL paths.
After login it also uses the user's relays and search relays alongside hardcoded relays, with a relay status display. It is described as work-in-progress with limited Web of Trust features, low performance, frequent crashes, and a preference for showing false positives rather than too little.

- Filter by author using NIP-05 names, npub, or @me with login
- Filter notes by images, YouTube links, highlights, and code snippets

- View profiles, events, and hashtags via direct NIP-19 URL paths
- Use user relays and search relays after login with relay status display
Best for: People who search Nostr notes and want modifier-based text search and direct identifier lookup.
