The page doesn’t show enough to say what kind of site it is (a shop, a blog, an app…).
More about it: Wikidata, profiles, AI use, page facts
AI use
- AI training: asks CCBot, Bytespider, meta-externalagent and Amazonbot to stay away.
- AI assistants: may read it for the people who ask them.

Built with AI?
AI Website DetectorNo AI builder traces found.
We look for what AI site builders such as Lovable, Bolt and v0 leave in a page. Code written with an AI assistant such as Cursor, Claude Code or ChatGPT leaves nothing to find, so we can’t tell whether AI helped.
AI traces: None found
How we know
AI site builders leave traces in the sites they make. We look for the traces of 53 of them and show every match with the line it came from, so you can check it yourself.
We test this on 2,275 sites whose makers we know, and publish what we get wrong.

Structured data
Now None found.
Add schema.org structured data, as JSON-LD, to the home page’s HTML.
Details
Why it matters: Structured data tells AI tools and search engines what the site is: a company, a shop, a product.
Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)Add schema.org structured data to the home page of https://sinonim.org as JSON-LD, in a <script type="application/ld+json"> tag in its HTML: an Organization with its name, url, logo and sameAs links to its official profiles, and a WebSite with its name and url. Add the type that fits what the site offers too, such as Product, Article or LocalBusiness. Use only facts that are true of the site.
Optional: a fix few sites have yetup to +3 points

Links for AI tools
Now None in the home page’s headers.
Point AI tools to the site’s files in the home page’s Link header.
Details
Why it matters: A Link header points AI tools to a site’s files from any page, without guessing addresses.
Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)Make the home page of https://sinonim.org send a Link header (RFC 8288) that points AI tools to the site’s files, for example: Link: </sitemap.xml>; rel="sitemap", </llms.txt>; rel="describedby"; type="text/plain". List only files the site serves.

None of the 27 other AI crawlers we know is kept out.
What it tells AI crawlers
It gives no Content Signals and no “noai” tag.
Like 29% of the 482 popular sites whose robots.txt we’ve read since 29 Oct 2026, it keeps at least one AI training crawler out. Of the 609 popular sites we’ve checked since 29 Oct 2026, 9% have a page drawn by scripts, 2% send a Markdown copy, 9% have an llms.txt and 3% offer a file for AI agents. How many websites block AI crawlers?
We read the site once, as our named bot: its robots.txt, read as crawlers read it, its home page and the files AI tools ask sites for. What we couldn’t read says so. robots.txt asks and doesn’t enforce: a firewall can treat AI crawlers differently from us.
