Share text, rendered markdown, syntax-highlighted code, or static HTML reports with inline CSS and SVG. Read a public ctxt.io link back into your conversation, or revoke a link you created using its private deletion token. Anyone holding the share URL can read its content. Do not share credentials or sensitive personal data. HTML is sanitized and JavaScript never executes. Links created through this plugin display without Context advertisements or upgrade controls. Expired and deleted links are unavailable; password-protected links cannot be opened by this plugin.",
