How is it different from Google Custom Search?

TutuSoo returns AI-facing structured results + source attribution + llms.txt, tuned for Chinese with jieba; the public tier is free to try.

Are there quota caps?

With a key it counts per-key rate_limit with X-RateLimit-* headers; the public tier is per client IP.

jieba tokenization gives better long-tail Chinese recall.

Can results be traced to a source?

Yes, each result carries a source tag.

Google Programmable Search (Custom Search JSON API) bills per query with limited daily quota. If you want more flexible, cost-controllable retrieval for AI apps, TutuSoo is a viable alternative.

TutuSoo returns structured JSON with source attribution, supports llms.txt, and tokenizes Chinese with jieba — real-time retrieval for RAG, agents and AI apps, with clear per-key limits and a free public tier.
