What is AIWebIndex?
AIWebIndex is Lyrenth's scheduled crawler for building an AI-readable index of the public web. Pages are stored and served to AI agents as clean, attributed documents. You can set up Agent Analytics to see when AIWebIndex visits your website.

Why Is AIWebIndex Visiting My Website?
AIWebIndex is adding or refreshing pages in Lyrenth's index after discovering them through sitemaps, links, or earlier fetches. Lyrenth can serve the stored pages to agents with attribution and source links.
Should I Block AIWebIndex?
It depends. Blocking AIWebIndex stops future fetches and keeps disallowed pages out of Lyrenth's attributed index. Lyrenth says it does not train foundation models on crawled content, but its policy allows licensing from verified domains. It does not affect traditional search rankings. For context, 8% of the top websites we track currently have robots.txt rules for AIWebIndex.
How Do I Block AIWebIndex Using Robots.txt?
Add this rule to your robots.txt file to block AIWebIndex from accessing your website, or use Automatic Robots.txt to block all AI search crawlers at once. You can customize which pages are blocked by swapping out / for a different path.

Frequently Asked Questions
What Traffic Patterns Should I Expect From AIWebIndex?
AIWebIndex revisits your site on a flexible schedule, often requesting several pages in a burst. Activity usually increases when your content changes or its index refreshes, with quiet intervals between crawl passes.
Does AIWebIndex Follow Robots.txt Rules?
Yes. Lyrenth says AIWebIndex honors Disallow and Crawl-delay rules, limits aggregate traffic to one fetch every two seconds per domain unless Crawl-delay is longer, and treats a site as disallowed when robots.txt cannot be read and no cached copy is available. Agent Analytics can verify whether it follows those rules.
Is AIWebIndex Used for AI Model Training?
No. Lyrenth says it does not train foundation models on crawled content, although its policy allows content licensing from verified domains.
Does Blocking AIWebIndex Affect AI Search or Citations?
Yes. Blocking AIWebIndex can keep future copies of your pages out of Lyrenth's index, reducing their availability to agents that retrieve content from it with attribution and source links.
Does AIWebIndex Access Private Content?
No special access. AIWebIndex can reach only content available to anonymous visitors. Make sure staging sites and other sensitive areas require authentication.
How Can I Verify a Request From AIWebIndex?
Agent Analytics tracks visits from AIWebIndex and every other known AI agent, crawler, and scraper, then authenticates each visit using AIWebIndex's published verification method. You can also check your server logs for requests whose user-agent string contains "AIWebIndex". Look for bursts that follow links across several pages and recur over time. A matching log entry alone is not proof because any bot can claim to be AIWebIndex.
How Is AIWebIndex Different From Other Lyrenth Agents?
Lyrenth operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
- AIWebIndex-Agent: AIWebIndex-Agent fetches a page into Lyrenth's index when an agent requests a URL that is not yet indexed or explicitly requests a fresh copy.
