What is the Dyslexia Ruler?

The Dyslexia Ruler is a colored bar that appears on screen to help you focus on one line of text at a time. It works like a physical reading ruler that you might place on a book.

The ruler can follow your mouse cursor as you read, or you can set it to stay in a fixed position. This helps you keep track of where you are and prevents your eyes from jumping to other lines.


Who is This For?

This feature is helpful for:

  • People with dyslexia who lose their place while reading
  • Anyone who finds long lines of text hard to follow
  • People with attention difficulties who get distracted by other text
  • Students reading dense paragraphs or textbooks
  • Anyone who wants help tracking text line by line

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 two tabs at the top: Tools and Settings.

Make sure the Tools tab is selected. This is where you will find the Dyslexia Ruler toggle.


Step 5: Turn on Dyslexia Ruler

In the Tools tab, look for Dyslexia ruler.

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

A colored ruler bar will immediately appear on the screen.


Step 6: Customize the Ruler

To adjust how the ruler looks and behaves, click on the Settings tab at the top of the panel.

Here you can change the height, width, color, and other settings to make the ruler work best for you.


Ruler Settings

In the Settings tab, you can customize the following:

  • Height – Adjust how tall the ruler bar is. A taller ruler covers more lines, while a shorter ruler focuses on a single line.

  • Width – Control how far the ruler extends across the screen. You can make it cover the full width or just part of the page.

  • Color – Choose a color for the ruler. Popular choices are light blue, yellow, or beige. Pick a color that is comfortable for your eyes.

  • Brightness – Make the ruler more or less transparent. Lower brightness lets you see more of the text behind the ruler.

  • Follow Cursor – When turned on, the ruler moves with your mouse cursor. When turned off, the ruler stays in one place.

  • Position – When Follow Cursor is off, you can set exactly where the ruler appears on the screen.

Tip: Try enabling Follow Cursor mode so the ruler automatically moves to wherever you are reading. Combine this with a soft color like light blue or cream for comfortable reading.

This extension has been an absolute lifesaver. I have that fantastic combo of ADHD and Dyslexia while trying to go through college. I have difficulty keeping letters in order, seeing the gaps between words, and with ADHD on top, I lose focus A LOT. The immersive reader has been my new best friend. It drowns out the rest of the content on the page, changes the font to something I can read, and highlights the word as it reads to me. My eyes are forced to keep going in the right direction. I can slow down and pay attention to what I'm reading. I don't even have to go back and read the same paragraph 5 times to understand it! The screen overlay has been outstanding for eye strain and being able to distinguish between words and spaces. The custom font and spacing for research articles have been an enormous advantage! I can actually read the research papers now and not have this daunting 2 column fine print page to squint over.All around, this has been the best purchase I've ever had. I use this every day, with every assignment. I don't even struggle with story-based questions anymore. The immersive reader helps me read, listen, and understand the question all at once. I am still exploring what I can use this with and how it can make my academic career, and I keep getting impressed with every new way I find to use it. Seriously, try it out. You won't regret it at all. Even if you don't have dyslexia or ADHD, just try it out. You might find that it helps you understand the content you're trying to learn even better!

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.
