FAQ
What is Nostr?
Nostr (Notes and Other Stuff Transmitted by Relays) is a decentralized protocol for social networks. Unlike Twitter or Instagram, there's no central server. Your content spreads through independent relay servers, and nobody can ban you.
Why doesn't Google index Nostr?
Google crawls websites by URL. Nostr isn't a website — it's a protocol. Content is stored on thousands of different relay servers in a special format that Google doesn't understand.
How does nostr.spot index Nostr?
The service connects to major relay servers, collects publications, profiles, and articles, and stores them in a searchable database.
What does AI INDEX mean?
It's the probability percentage that a profile's content is AI-generated or bot-created. 0-20% = likely human. 80-100% = likely bot. Based on analysis of posting patterns, content quality, and behavior.
Why does adding a profile cost money?
5,000 sats (~$5) covers compute resources and prevents spam. Without payment, bad actors could add millions of fake profiles.
Do I need an account to use it?
No. Search is free and doesn't require registration. To add a profile, you only need a Lightning wallet for payment.
What languages are supported?
16 languages: English, Spanish, Portuguese, German, French, Italian, Japanese, Korean, Chinese, Turkish, Arabic, Polish, Dutch, Ukrainian, Czech, Russian.
