BotGentz - Reading Ruler

BotGentz — Reading Ruler is a lightweight browser extension that adds a customizable reading ruler overlay to any page. It highlights one line of text at a time while dimming the rest of the page, helping you focus on what you're reading without distractions.

Click Start to activate the ruler. Drag it with your mouse to move it up and down, or use your keyboard arrow keys for precise control. The ruler is designed to work on any website with text content — articles, blogs, documents, e-books, and more.

Free trial — 15 reading sessions — no credit card required. Upgrade to the full version with a one-time payment of $3.99 and use the ruler unlimited times forever. No subscriptions, no recurring fees.

Privacy-first: BotGentz runs entirely in your browser. No data is collected, stored, or transmitted to any third party. All operations are performed locally on your device.

Please note: The reading ruler only affects your current browsing session and does not modify any content or settings permanently. Works on any website with text content.
