What is Line Focus?

Line Focus (also called Focus Ruler) creates a spotlight effect on the line you are reading. It dims everything on the page except for one strip of text, making it much easier to concentrate.

Think of it like shining a flashlight on just one line while the rest of the page fades into the background. This helps reduce visual clutter and keeps your attention on the text you are reading.


Who is This For?

This feature is helpful for:

  • People with dyslexia who get distracted by surrounding text
  • Anyone with ADHD or attention difficulties
  • People who find busy web pages overwhelming
  • Students who need to focus while studying
  • Anyone who wants to reduce visual distractions while reading

Step 1: Open Helperbird

Click the Helperbird icon in your browser toolbar. It looks like a small owl and is usually in the top-right corner of your browser.

This will open the Helperbird menu.


Step 2: Open the All Features Section

Scroll down to the bottom of the Helperbird menu. You will see a section called All Features.

Click the arrow next to All Features to expand it and show all available features.


Step 3: Find Dyslexia Support

Look through the list of features until you see Dyslexia support.

It has a purple icon with a brain symbol on it.


Step 4: Open Dyslexia Support

Click on Dyslexia support to open it.

A panel will appear with three toggles: Dyslexia ruler, Focus ruler and Reading guide, with a Settings section below them.

The Focus ruler toggle is the one you need for Line Focus.


Step 5: Turn on Line Focus

In the panel, look for Focus ruler (also called Line Focus).

Click the toggle switch next to it to turn it on. The toggle will turn green when it is enabled.

The page will immediately dim except for a strip of text where you can focus.


Step 6: Customize the Focus

To adjust how the line focus looks, scroll to the Settings section below the toggles in the same panel.

Here you can change the size, color, and opacity of the focus area.

Focus Settings

In the Settings section, you can customize the following:

  • Height - Adjust how tall the focused reading area is. Make it taller to see more lines or shorter to focus on just one line.

  • Color - Choose the color of the dimmed area around your focus strip. Darker colors create more contrast.

  • Opacity - Adjust how dark the dimmed area is. Higher opacity makes the surrounding area darker.

Tip: For the best reading experience, use a dark mask color with a higher opacity. The focus area follows your mouse automatically, creating a spotlight effect as you read down the page.

They were super fast with response time when helping me meet a deadline and very kind when corresponding. If the app is anything like their customer service then I am happy with my purchase!

It's just a one-stop solution if I want to customize my page. With very good UI design.

Talking to the Helperbird support team during their live stream was a great experience. They gave me a preview of what's coming to Helperbird for Firefox, and I'm really excited about it. I'd give a 5/5 rating for the current features and the sneak peek.
