Highlighty frequently asked questions

This occurs because some elements hide behind others within a document, depending on the structure of the specific website. You shouldn't be bothered by that; feel free to skip the invisible element if you come across one.

Highlighty supports Mozilla Firefox 109+ and Chromium-based browsers such as Chrome, Edge, Opera, and Brave. Safari is not listed as a supported browser on this site.

Yes. On Chromium-based browsers, Highlighty can open searchable PDFs in PDF Search as part of trial and PRO. You can add the current PDF from the popup, open PDF Search directly, choose one or more local PDFs, or drag them into PDF Search. PDF Search can keep multiple PDFs open with the same query list. It works on PDFs with selectable text; scanned, image-only, and password-protected PDFs are not supported.

Yes. Highlighty includes a free plan with feature limits. New installs can receive up to 2 days of PRO access, and signing in can unlock 5 additional trial days before upgrading to a paid plan.

The current flow is app-managed, not checkout-managed. Install Highlighty to start the guest PRO window if it is enabled, then register and sign in to unlock the account trial extension. You can upgrade to paid at any time during either trial state. Choosing a paid plan starts billing immediately and ends any remaining trial time.

We do not know of websites banning users simply for using Highlighty, but each site sets its own policies and some pages restrict what browser extensions can do.

The extension can keep working on pages that are already loaded in your browser. Highlighty can also work with local PDFs opened or dragged into PDF Search from your device. It cannot search content that has not loaded yet, and scanned PDFs without selectable text are outside the current PDF scope.

No. Highlighty changes the current page view in your browser only. Refreshing or reopening the page removes those injected highlights and UI elements.

Yes, if your browser allows the extension in incognito or private windows and you enable that permission. Some URL-based features may be limited there.

The extension needs that permission to save and retrieve the settings and queries at every startup of the application.

Account data tied to our services is removed after deletion. Settings or exported files stored locally in your browser stay on your device until you remove them.
