Question 1

How is TutuSoo different from Google / Baidu?

Accepted Answer

TutuSoo is a search engine with its own index (spider-rs crawler + Tantivy BM25) plus web fallback, focused on high-authority sites, and it additionally offers an AI-first search API. When local results are thin, external search fills in.

Question 2

Do I need to sign in to search?

Accepted Answer

No. Search itself is fully anonymous; sign-in only saves collections and query history, deletable per-item or all at once.

Question 3

How good is Chinese search?

Accepted Answer

Tuned specifically: the index tokenizes title/body with jieba, so a Chinese phrase recalls properly instead of being treated as one token.

Question 4

What is “I’m Feeling Lucky”?

Accepted Answer

Like Google’s: it jumps straight to the top result’s site; on no result or error it falls back to the normal results page.

Question 5

How do I get an API key?

Accepted Answer

Request a key on the developer page. You can also try the public tier (rate-limited per client IP) for free without a key.

Question 6

What format does the API return?

Accepted Answer

Uniform structured JSON: a results array where each item has title / url / snippet / source (local index / brave fallback) — ready to feed a model.

Question 7

How does it differ from Firecrawl / Exa / Tavily?

Accepted Answer

Firecrawl leans to single-page scrape-to-Markdown, Exa to English vector retrieval, Tavily to returning a synthesized answer; TutuSoo leans to “web-wide retrieval of structured raw results with explicit sources”, stronger Chinese, with synthesis under your control. See the alternative pages.

Question 8

Is there rate limiting?

Accepted Answer

With a key it counts per-key rate_limit with X-RateLimit-* headers; without a key it uses the public per-IP tier.

Question 9

Will you use my searches for ads?

Accepted Answer

No. TutuSoo builds no user profile and does no ad targeting on your searches; sign-in only powers collections and history.

Question 10

Can I delete my search history?

Accepted Answer

Yes. When signed in you can delete a single recent search on the home page, or clear all at once, per the privacy policy.

Question 11

Do I have to use a Tutu account?

Accepted Answer

No. Use it anonymously, or sign in once with your Tutu account (tutuid) to sync collections and history across the Tutu family.
