What is Sarashina Search?
Sarashina Search is an on-demand AI fetcher operated by SB Intuitions. It retrieves a page only when a user explicitly asks an AI assistant or agent to read, summarize, or act on a specific URL. Because it is triggered by real user intent rather than bulk crawling, blocking it mainly prevents users from pulling your content into SB Intuitions's assistant.

Sarashina Search uses the user-agent token SBIntuitions-SearchBot. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What does Sarashina Search do?
Understanding Sarashina Search's purpose helps you decide whether to allow or block it.
- Fetches a page only when a user asks an AI assistant to read it
- Summarizes or extracts the URL the user provided
- Triggered by real user intent, not bulk crawling
- Low traffic volume compared with training crawlers
- Blocking it prevents users from pulling your content into the assistant
Sarashina Search in context
Sarashina Search is a user-triggered agent operated by SB Intuitions. In plain terms, it fetches a page when a person asks an assistant or app to open it. Our database files it under AI and LLM crawlers and ranks it Tier 2, important crawlers from established AI and search operators. 74 of the 104 AI and LLM crawlers in our database share this tier.
Its safety rating is safe and its blocking impact is low. So the decision about Sarashina Search rests on what you want from SB Intuitions, not on its behaviour. How we rate safety and impact.
How site owners treat Sarashina Search
Our robots.txt study of the Tranco top 10,000 did not track SBIntuitions-SearchBot as a named token, so we do not publish an adoption figure for it. If you run a large site, your own logs are the best evidence of how often it visits.
Does it follow robots.txt?
Sarashina Search's operator does not clearly document how it treats robots.txt. Write the Sarashina Search rule anyway, then confirm in your logs that its requests stop.
SB Intuitions crawlers and close alternatives
Sarashina Search is one of 2 SB Intuitions crawlers in our database. A User-agent: SBIntuitions-SearchBot group controls Sarashina Search only; the other SB Intuitions tokens below need their own lines.
SBIntuitions-SearchBot: this crawler (Tier 2)SBIntuitionsBot: SB Intuitions Crawler, collects pages to train AI models (Tier 2)
To give Sarashina Search the same answer as its siblings, stack User-agent: SBIntuitions-SearchBot with their lines above one set of rules; to treat Sarashina Search differently, give it its own group.
Other AI and LLM crawlers that do the same job (fetches a page when a person asks an assistant or app to open it) include ChatGPT Agent from OpenAI, ChatGPT Operator from OpenAI, ChatGPT-User from OpenAI, ChatGPT-User/2.0 from OpenAI, Claude-SearchBot from Anthropic, Claude-User from Anthropic. Deciding about Sarashina Search is usually a decision about the whole group, so check how your file treats these too.
We first recorded SBIntuitions-SearchBot on September 22, 2026. SB Intuitions documents it on sbintuitions.co.jp, and we recheck that page before each release.
Which rule Sarashina Search actually follows
Sarashina Search reads exactly one group in robots.txt, the most specific one that names SBIntuitions-SearchBot, and never combines rules across groups. This short file shows the trap:
User-agent: *
Disallow: /private/
User-agent: SBIntuitions-SearchBot
Disallow: /drafts/
- Find the group. Sarashina Search looks for a group naming
SBIntuitions-SearchBot. One exists, so it ignoresUser-agent: *completely. - Apply only that group. It is refused
/drafts/and nothing else. - The surprise.
/private/is open to Sarashina Search, because that rule lives in the*group it no longer reads. To keep it out of both, repeatDisallow: /private/inside its own group.
Test yourself: does a rule under User-agent: * apply to Sarashina Search if the file also has a User-agent: SBIntuitions-SearchBot group?
No. Once a group names it, Sarashina Search reads only that group. Put every rule you want it to follow inside its own group.
Test yourself: will blocking Sarashina Search remove your pages from AI answers?
Often, yes. Sarashina Search is a user-triggered agent, so pages it cannot fetch can drop out of the answers or results it supports.
Test yourself: is User-agent: sbintuitions-searchbot the same as User-agent: SBIntuitions-SearchBot?
Yes. RFC 9309 makes user-agent matching case-insensitive. Paths are a different story: Disallow: /Blog/ does not block /blog/.
Should you allow Sarashina Search? Decide by situation
| If you are... | Recommended setting |
|---|---|
| You publish content and want AI answers to cite it | Allow it. Sarashina Search fetches pages for answers, so blocking it can remove you from them. |
| You license content and want to stop AI training | Blocking it does not stop training, because Sarashina Search is a user-triggered agent. Block the operator's training crawler instead. |
| You run an online shop | Allow it on product and category pages, which are the pages shoppers ask assistants about. |
| Your server is under load from bots | Rate-limit before blocking. It is rated safe in our database. |
Check Sarashina Search on your own site
- Open
/robots.txton your domain and search forSBIntuitions-SearchBot. If it is not named, it followsUser-agent: *. - List the
Disallowlines in the group Sarashina Search follows and test your key URLs against them; the longest match wins, andAllowwins a tie. - Look beyond the file. A firewall or bot manager can refuse Sarashina Search even when robots.txt allows it, and that never shows in the file.
- Run our live AI crawler test to see how Sarashina Search and every other crawler we track are treated in one pass, including firewall refusals.
Common mistakes with Sarashina Search
The errors we see most often with Sarashina Search in the files and firewalls we test:
- Assuming a robots.txt rule will stop Sarashina Search. User-triggered fetches act for a person, and some operators say robots.txt may not apply to them. Check the operator's statement above.
- Blocking Sarashina Search as if it were a bulk crawler. It fetches one page because a person asked; blocking it means that person's assistant cannot read your page.
- Counting Sarashina Search visits as crawl volume. Each request maps to a real user question, which makes the paths it requests a useful signal of what people ask about you.
All three hide inside a file that looks correct, so check Sarashina Search from outside after every change.
Spotting Sarashina Search in your logs
robots.txt says what Sarashina Search may do; your access logs show what it actually did.
Count requests
On a server with standard Nginx or Apache logs, this counts matching requests per day (adjust the log path for your host):
grep -iE "SBIntuitions-SearchBot" /var/log/nginx/access.log \
| awk '{print $4}' | cut -d: -f1 | sort | uniq -c
And this shows which paths it requested most, which is the quickest way to see whether your Disallow lines are being respected:
grep -iE "SBIntuitions-SearchBot" /var/log/nginx/access.log \
| awk '{print $7}' | sort | uniq -c | sort -rn | head -20
Check the requests are genuine
Anyone can send the Sarashina Search user-agent, so confirm the source before acting on a match:
SBIntuitions-SearchBot: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Sarashina Search request with caution.
