Free Tools: Measure and Fix Your AI Visibility, One Tool at a Time
Everything CapstonAI ships lives here: the free AI visibility audit, the Chrome audit extension, the WordPress plugin, the Shopify app, the content engine, and the free calculators. They all attack the same problem from different angles: AI answers cite fewer than 7 sources on average (Zhang, He & Yao 2026), and if your business is not one of them, your buyers are being sent to someone else. Pick the tool that matches where you are.

- Find the structural gaps: install the Chrome extension and audit your money pages.
- Fix at the source: plug in the WordPress plugin or Shopify app and correct metas, schema, llms.txt and alt tags where they live.

Each free tool works alone. Together they close the loop: measure → fix → verify. That loop is the difference between hoping AI engines find you and knowing what they see.
Frequently asked questions
Are these tools really free?
The audit, the Chrome extension and the Shopify app’s base plan are free; the WordPress plugin is freemium. The full platform — continuous tracking and correction — is paid, with a 7-day trial.
Which tool should I use first?
The free AI visibility audit. It tells you whether you have a visibility problem and how big it is — the rest of the stack is how you fix it.
Do the plugin and the app overwrite my content automatically?
No. Both work with human approval: suggestions are generated, you review and apply. Nothing ships without you.
Do I need the platform to use the free tools?
No. Each free tool works standalone. The platform adds the continuous loop: tracking mentions per engine, diagnosing gaps and verifying that fixes moved the needle.
