xbrushbot-link

xbrushbot-link/1.0 (+https://xbrush.ai/docs/bot; link preview) is the user agent XBRUSH uses to build a link preview.

When it visits a page

It visits a page only when an XBRUSH user pastes that page's link into their workspace chat.

• One request per pasted link, at the moment of pasting.
• If the user then asks the AI to use the link, the page text or the preview image may be fetched once more, at that moment.
• No crawling, no link discovery, no scheduled visits. Every request is made on behalf of a person for a single link they chose.

What it reads

• Title, description and preview image URL (Open Graph, Twitter Card or <title>).
• On request, the main text of the linked page.
• YouTube and TikTok are read only through their official oEmbed endpoints.

Limits: 5 seconds, 2 MB, text/html only, HTTPS only, up to 3 links per message, rate limited per user.

What it keeps

Only the title, description and preview image URL, as part of the user's message. Page text and images are not stored.

robots.txt

Because each request is a single fetch made for a person who chose the link, xbrushbot-link works like other user-initiated fetchers (such as ChatGPT-User or Claude-User) and does not apply crawler rules from robots.txt.

How to opt out

The bot honors the following signals. When one is present, it discards what it read and the user sees "no preview".

• <meta name="robots" content="noai"> (also noimageai)
• X-Robots-Tag: noai response header
• <meta name="tdm-reservation" content="1">

To block at the network level, block the user agent xbrushbot-link/1.0.
