What is CiteKit?
CiteKit is a small, one-time utility for site owners who want their public website copy available in formats that AI agents can parse. You paste a public HTTPS URL and CiteKit previews an llms.txt file, schema JSON-LD, an FAQ markdown file, and a README from that origin. You read the preview before deciding whether to buy the generated ZIP.
The product is designed for a website’s own content and is not an AI model or an agent runtime. It does not send site content to an external AI model, change search rankings, create citations, or provide monitoring. It is not a WAF or security service. The generated files are delivered for you to host and maintain; they are not a guarantee that an AI system will read or cite them. CiteKit is sold for US$19 one time per site through Paddle.
The checker fetches public pages only, does not sign in to the site, does not execute its JavaScript, and has request limits. Do not submit credentials, secrets, or URLs containing access tokens. Contact: idealstoronto@gmail.com. CiteKit is intended for developers, founders, and site owners who want a concise, honest technical brief for their own origin. It is a focused publishing aid rather than rankings, citations, monitoring, or SEO theater.
