Who it is for
Competitive analysts, marketers, and investors researching properties they do not own.
Similarweb
Traffic, keyword, and audience data for sites and apps
Overview
What Similarweb does
Similarweb Inc makes its market intelligence data queryable from ChatGPT, covering both websites and mobile apps. A question might ask for a competitor's traffic breakdown, the keywords a brand ranks for, the demographics behind a site's audience, or how one property benchmarks against others in its industry.
Because data is fetched as the question is asked, comparisons can be built on the spot: traffic trends for a domain against its closest rivals over recent months, or the geography and search terms of two audiences side by side.
The developer names acquisition analysis as a common use, including which channels and referring sites bring visitors to a domain. Marketers, analysts, investors, and strategists are the readers it identifies.
What stands out
Coverage takes in web and mobile app properties together, with search and audience data alongside traffic.

Where Similarweb is listed
Similarweb ships this on both marketplaces: Similarweb is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
Similarweb publishes 22 tools to Claude, deeper than 72.2% of the 1,253 Claude-listed connectors.
The median Claude-listed connector filed under Productivity publishes 12, so this one runs 10 tools above its bucket's median and ranks 133rd of 462 by tool count.
It falls in the 21-50 tools band, which holds 20% of the Claude directory.
Similarweb publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
