Free vs. Pro
MarTech Inspector's core features — detection and editing — are entirely free. For deeper verification, a one-time Pro upgrade is available. It's a single payment, not a subscription, and it's yours to use for good.
About the 15-day free trial
For 15 days after installing the extension, you can try every Pro feature with no license key required. If you like what you see, purchase Pro before the trial ends.
- The trial starts on the day you install the extension.
- While the trial is active, the plan bar at the top of the side panel shows the days remaining.
- When the trial ends, the extension automatically reverts to the Free feature set (none of your saved data is deleted).
- Purchasing Pro at any time — even after the trial ends — restores full access.
