What is LinerBot?

LinerBot collects pages for Liner's search engine. Liner uses that index in its AI research and answer assistant, which presents sources with its responses. This is background collection for the product rather than a browser acting through one user's session.

The LinerBot documentation says the crawler gathers information from the internet and indexes it to improve search. A request may therefore arrive without a person asking about that exact page at that moment. The documentation does not publish a crawl schedule or promise when an updated page will be revisited.

Pages that LinerBot can retrieve may become candidate sources for Liner answers. Access alone does not guarantee that Liner will quote, rank, or link a page, since the source material only establishes collection and indexing. Blocking the crawler removes that route into Liner's search corpus.

Liner documents a search and answer use for the collected material. Neither the bot record nor the operator page says whether LinerBot content is also used for model training. Treat training use as unknown rather than presenting this token as a confirmed training opt-out.

The published full user agent is Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; LinerBot/1.0; +https://docs.getliner.com/docs/linerbot). This directory marks the bot as unverifiable and does not mark its IPs as verified. Liner notes that its IP pool can change, so the LinerBot string by itself is identification, not authentication.

There is a source disagreement about robots.txt. Liner's documentation supplies both whole-site and path-specific rules, and this bot classifies the bot as respecting robots.txt. Cloudflare's entry for LINER Bot currently sets followsRobotsTxt to false. Publishers can use the documented directive, but should check logs and add an edge rule when compliance is a hard requirement.

Relevant for AI search

Is LinerBot relevant for AI search?

Yes. LinerBot collects pages for an AI product, so what it can crawl influences how AI systems describe your brand.

LinerBot crawls and indexes pages so the AI search or assistant behind it can retrieve them at answer time. A page it has never fetched cannot be quoted, summarized, or linked in that product's answers, so most sites keep it allowed to stay citable. Blocking it removes your pages from that AI surface and hands those citations to competitors.

How to handle LinerBot

Allow LinerBot on pages you want Liner to consider as sources. Exclude private areas, faceted crawl traps, and pages that you do not want copied into its search index. Liner's documentation says path-level Allow and Disallow rules are supported.

To deny the crawler site-wide, use its stable token:

User-agent: LinerBot
Disallow: /

The operator documentation presents robots.txt as the control, but Cloudflare's bot directory records the bot as not following it. Verify the result in access logs. If requests continue after the crawler has had time to read the file, enforce the restriction at the CDN or origin rather than assuming the user agent is genuine or compliant.

Examples

  • A research publisher allows LinerBot to crawl public explainers while excluding subscriber account and checkout paths.
  • After correcting a data table, an editor watches for a later LinerBot request but does not assume that the fetch guarantees a new citation.
  • A security team sees the LinerBot token from an unrecognized address and treats it as unverified until the traffic can be checked against current operator information.
