Slurp Score in one click
Open any page, click the cup, get a 0-100 score with a grade. About 60 checks across 11 categories run in seconds, entirely inside your browser.
Engine readiness, per engine
ChatGPT, Google AI Overviews, Perplexity and Claude each get their own verdict. If robots.txt blocks one engine’s crawler, you see exactly which one and exactly what to change.
What AI sees vs what you see
The audit compares the raw HTML that crawlers receive against the rendered page in your tab, and tells you how many of your words actually reach AI systems. No other SEO extension shows this.
Ranked fixes, not a checklist dump
Failed gates first, then the changes with the most impact. Every finding comes with a one-line fix you can paste into a ticket, and the evidence behind the check.
Private by architecture
Audits run locally using the temporary permission you grant by clicking. No account, no cookies, no page content sent anywhere. Scan history stays in your browser.
Permissions, explained
The extension requests three permissions and nothing else. activeTab grants temporary access to the page you are on, only after you click. scripting reads the rendered page for the raw-vs-rendered comparison. storage keeps your scan history on your device. There are no broad host permissions and no background data collection - see the privacy policy.
What it checks
The full methodology, including weights and the checks behind every category, is public on the scoring page. Each category also has its own checker page with the complete check list, generated from the engine itself.
