FAQ

LinerBot questions

What is LinerBot?

LinerBot is a bot that fetches single pages on demand for an AI assistant, and its operator has not been publicly identified. LinerBot is the web crawler used by Liner AI assistant to gather information from academic sources and websites to provide accurate answers with line-by-line source citat…. No IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine and a robots.txt rule alone will not stop a forgery.

Does LinerBot respect robots.txt?

Not documented. No operator statement says whether LinerBot reads robots.txt, so add the rule but verify in your logs that the requests actually stop.

How do I verify a request really came from LinerBot?

You cannot, at least not from the request itself. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.

How do I block LinerBot?

Add the LinerBot token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.

Will blocking LinerBot hurt my search rankings?

Blocking LinerBot means a person who asks about one of your URLs gets an error instead of a summary. That is a support and reputation trade-off, not a training one.
