Why it’s actually free –
Most of these checks (density, readability, schema, slugs, robots.txt, sitemaps) are pure text/math that a browser can do on its own — no paid API needed. The only optional paid piece is the AI Writer tab, and that uses your own API key, sent straight from your browser to the provider. Nothing here ever touches a third-party server.
Privacy –
Your article text, WordPress credentials, and any API key stay in this browser tab’s memory only. Refreshing the page clears everything — nothing is saved to cookies, localStorage, or any database.
FAQ –
Is this tool really free, no signup? Yes. Every tool works with no account and no payment. The only optional item is AI Writer, which needs your own AI provider key.
Do I need to install a plugin? No. It runs as a single Custom HTML block. WordPress publishing uses WordPress’s own built-in Application Passwords feature (available since WordPress 5.6) — no plugin required.
Is my content or WordPress password sent anywhere? No. Everything stays in your browser’s memory for the current page load and is sent only directly to your own WordPress site’s REST API over HTTPS.
Can I use this on any WordPress site? Yes, as long as your site allows Application Passwords (enabled by default on self-hosted WordPress 5.6+ over HTTPS).
