How to Use Explain Mode in the Screenshot Reader

Learn how to turn on Explain mode so Helperbird explains a chart, diagram or paragraph in plain language instead of just reading the words back to you.

What Explain Mode Does

Normally the Screenshot Reader gives you back exactly the words it found in a picture. Explain mode does something different: it explains what you captured, in plain language.

Point it at a chart and it tells you what the chart shows. Point it at a paragraph you have read three times and it tells you what it means.


Who is This For?

This is helpful for:

  • Anyone stuck on a paragraph that will not go in, however many times they read it
  • Students meeting a diagram, chart or table in a subject they are new to
  • People who find a formula easier to understand described in words
  • Anyone reading in a second language

Step 1: Open the Screenshot Reader

Open Helperbird, go to All Features, and open Screenshot Reader.


Step 2: Turn On Explain Mode

Scroll down to Settings inside the panel and turn on Explain mode.

This is a setting, not a one-off. It stays on until you turn it off, so remember to switch it back when you want the plain text again.


Step 3: Draw a Box

Press Start, then drag a box around whatever you want explained.

Step 4: Read the Explanation

The explanation appears in a card on the page. It has buttons to listen to it, copy it, or close it.

The listen button uses Helperbird's text to speech, so it uses the voice and speed you have chosen there.


When to Use It, and When Not To

Use it when the problem is understanding: charts, diagrams, formulas, dense or badly written paragraphs, or anything in unfamiliar jargon.

Turn it off when you want the actual words. If you are copying a quote, filling in a form, or need the text exactly as written, Explain mode gives you a description instead, which is not what you want. Switch it off and the Screenshot Reader goes back to giving you the text itself.

Huge fan of the zoom feature. It trumps the native zoom in your browser since the zoom level you set actually stays with you no matter what page you go to, which is very helpful and meshes well with the other features the app offers.

Helperbird is an excellent extension supporting a range of learning differences. Aside from providing many evidence-based dyslexia-assistive tools, the extension also functions as an easy-to-use, feature-rich web experience customization tool suitable to support a wide range of cognitive differences (i.e., color blindness and ADHD-related focus concerns, among others). Also, the developer is a very good person who supports the various learning-different communities in many ways, including by designing the free version of Helperbird to provide enough functionality to be beneficial to people who cannot afford to subscribe to the full-function version.
