Hilight Lens is based on the logic of "Cognitive Unloading," converting "logical identification" into "visual intuition" through color coding. Hilight Lens frees your brain from the low-level task of identifying keywords, allowing you to focus on higher-level logical thinking.

Hilight Lens excels in professional work (reviewing documents), language learning (marking new words), deep reading (tracking relationships), and information tracking (capturing specific metrics) where filtering key content from massive information is required.

Please check: ① Is the 'Group' containing the keyword active in Hilight Lens? ② Is the specific keyword toggled off in the Hilight Lens management panel? ③ Try refreshing the page to see if Hilight Lens takes effect.

Yes. You can add and highlight an unlimited number of keywords simultaneously in Hilight Lens, with independent color definitions for each keyword or group to build a clear visual index.

Currently, only one group's highlights can be active at a time in Hilight Lens. If you need to track multiple types of keywords simultaneously, we suggest placing them in the same group within Hilight Lens.

Yes. Hilight Lens supports 'Web-wide Synchronized Highlighting'. Keywords added or modified on any page in Hilight Lens will instantly apply to all open websites and tabs without needing a manual refresh.

Absolutely. Hilight Lens comes with beautiful preset color schemes that rotate automatically, and you can also freely define custom background and text colors for each keyword group in the Hilight Lens management panel.

By default, Hilight Lens is case-insensitive. Whether you enter a keyword in uppercase or lowercase, Hilight Lens will automatically match all forms of the word on the page (e.g., 'Apple' and 'apple') to ensure no key information is missed.

Yes. Hilight Lens introduces a 'One-click Keyword Toggle'. You can quickly hide or restore specific keyword highlights in the Hilight Lens management panel, perfect for decluttering your view without losing your Hilight Lens settings.

You can use the Hilight Lens 'Keyword Grouping' feature. Organize your keywords into custom groups (e.g., 'Work', 'Study', 'News') and activate only one group at a time in Hilight Lens. This allows you to switch contexts seamlessly and keep your focus on the current task.

You can use the 'Import/Export' feature in the Hilight Lens management panel. Simply click 'Export' to save all your Hilight Lens keywords, colors, and groups as a plain text file. To sync Hilight Lens to another device, just click 'Import' on that device and select the file.

Yes! Unlike many technical tools that use complex JSON or databases, Hilight Lens exports a human-readable plain text format. The Hilight Lens backup file includes clear comments and instructions, so even users without a technical background can easily add, delete, or modify keywords using a simple text editor (like Notepad).

Yes, but you need to enable Hilight Lens permission manually. Go to your browser's extension management page, find 'Hilight Lens', click 'Details', and check 'Allow access to file URLs' to use Hilight Lens on local files.

Completely. Hilight Lens adheres to the principle of 'Local Processing'. All your Hilight Lens keywords and settings are stored only locally in your browser. Hilight Lens does not collect or upload any user data.

Not at all. Simply put, the Service Worker is like the Hilight Lens 'background butler.' It goes to sleep to save your computer's memory and power when there's no work to do. As soon as you use Hilight Lens, it wakes up instantly. The 'inactive' status just means it's currently napping, not broken. It doesn't affect any Hilight Lens functionality.

This usually happens when Hilight Lens is updated and requires new permissions (e.g., to support a new AI platform domain). This is to add new features for a better user experience. Our privacy policy remains unchanged, and you can safely accept the permissions to continue using Hilight Lens. You just need to go to your browser's extension management page, find Hilight Lens, and click 'Accept permissions' or re-enable Hilight Lens.
