Your reading tools should be where the document is.

The Google Workspace add-on puts a Helperbird sidebar inside Google Docs, Google Slides and Google Sheets.


How to Install the Add-on

  1. Open a Google Doc, a Slides presentation or a Sheet.
  2. Click Extensions in the top menu.
  3. Choose Add-ons, then Get add-ons.
  4. Search for Helperbird.
  5. Click Install and accept the permissions.

You can also start from the Helperbird listing on the Google Workspace Marketplace (opens in a new tab).


What the Add-on Asks For

The add-on asks for two things:

  • Access to the file you have open, and no other file.
  • Permission to show the Helperbird sidebar inside the editor.

It cannot open, read or change anything else in your Google account.


How to Open the Helperbird Sidebar

  1. Click Extensions in the top menu.
  2. Choose Helperbird.
  3. Choose Open Helperbird.

The Helperbird sidebar opens beside your file, with a tile for each tool.

What you get inside depends on the file. See what the Google Docs sidebar does, what the Google Slides sidebar does and what the Google Sheets sidebar does.

There is no account to sign in to. If you have a subscription key, open the Pro tile, paste your key into the Subscription key box and click Save.

help deliver the world to some wh...

This is a great little extension, lightweight and non intrusive. With dyslexia its reading that's an issue, not the underlying intelligence. An aid such as this one, can help deliver the world to some who may not otherwise have received it. Great Work.

manipulate the font and font size...

Amazing Extensions in chrome. I Installed in my parents computer, because my dad have a poor vision, due to bad eye surgery. this extension really helps to have able to manipulate the font and font size for more comfortable use instead of chrome zoom feature. Because the chrome zoom feature is its overly zoom will cause the page looking super weird.

The free version can be installed...

Helperbird is one of the most helpful tools I've ever used. It has so many great features that not many other apps or software have. The free version can be installed and stay forever on your browser. Other companies don't always give you access for free or give access for free forever. When you do get access to the Pro version or other paid plans, you expand your opportunity to read and stay focused better. One of the other great things about Helperbird is their support service. They have a video for every single feature that you can use. They are simple and helpful videos that make the learning process a lot easier. In addition, they have great live chat support. They are super nice and helpful. They always encourage people to give suggestions on how to improve Helperbird. Why is this important? It shows they really care about people with disabilities or people in general.
