How It Works

Privacy-Aware by Design

Text generators and converters can run locally in your browser. URL-based checks use a bounded server route when a public page must be fetched.

Each experience discloses its execution boundary. The public audit uses a secured proxy lane, strict page and response limits, and does not trigger paid SEO or LLM data.

From meta tag checks to JSON-LD generators, the suite handles repetitive work while the audit connects individual signals into a prioritized view.

Clear Execution Boundaries

Local utilities stay local. Public URL checks disclose when a secured server fetch is required.
