Agntbase — AI Crawler Checker & Schema Markup Generator

Check AI crawlers and robots.txt, inspect Schema.org markup, and generate reviewed JSON-LD in one side panel.

Check crawler access, inspect schema markup and build reviewed JSON-LD without leaving the page. Agntbase Toolkit brings three tools into one side panel with one account and one subscription. CRAWLER ACCESS Read robots.txt rules for supported search and AI crawlers. See the matched rule and its source. After a completed rules check, you can use the included one-shot Agntbase server request to compare public access. Rules and a request from our checker do not prove that Google, ChatGPT or another real crawler visited your site. Confirming real visits requires site logs. Blocking a training crawler is not automatically a site error. SCHEMA CHECKER Inspect supported Schema.org structured data on the selected page. Review detected entities, missing facts, connections and conflicts. Export the evidence for your developer. This is a supported-checks tool, not an exhaustive Schema.org or Google rich-result validator. A correct result does not guarantee indexing, rich results or AI citations. LAYER BUILDER Capture public page facts locally, review the proposed values and generate supported JSON-LD and machine-readable profile files. Review existing markup before adding or replacing it. Download the code, retained original markup and installation guidance; compare rendered markup after installation. The extension does not invent unknown facts or publish changes to your site. Our optional profile format is not a mandatory AI standard. ONE PLAN FOR ALL THREE TOOLS One successful check or generation is free per Agntbase account, shared across all three tools. After that, choose US$4.99 per month or US$19.99 per year. Both plans include all three tools and renew at the selected interval. Reading facts in the builder, switching sections and downloading completed results do not consume another operation. Failed or cancelled operations do not consume the free use. Cancel renewal through Manage billing; access continues until the end of the paid period. Applicable tax is shown before payment. PRIVACY AND SCOPE Use the toolkit on a selected public HTTP(S) page after clicking the extension icon. Query parameters and fragments are omitted from reported URLs. Schema and page-fact analysis stays in your browser; those contents are not uploaded to Agntbase or Stripe. The optional crawler server request sends the selected public URL to Agntbase. Account and usage records support sign-in, billing and abuse prevention. Access tokens and the builder's temporary installation receipt use Chrome session storage, not synchronized storage. The receipt expires after 24 hours and is cleared on disconnect or browser restart. No form values, passwords, cookies or continuous browsing history are collected. Do not use it on private or sensitive pages. SUPPORT https://agntbase.com/account/extensions.html hello@agntbase.com Privacy: https://agntbase.com/account/extensions-privacy.html
