Google's app for iPhones has a new 'Simplify' tool. It uses AI to make hard or technical words on the internet easier to understand, and you don't have to leave the page.

Simplify uses a method from Google Research and Gemini to make difficult text easier to understand, keeping the important details. Google's tests showed that the simpler text helped people understand and remember the original information better.

Google probably hopes that by offering a feature like Simplify, people will continue to use Google's tools and services when they need help with difficult subjects, instead of using popular tools from other companies like OpenAI's ChatGPT.

You can use Simplify when you are in the Google app by choosing any text on a website you visit and tapping the "Simplify" symbol. A simpler version of the text will then appear, making it easier to understand and continue reading.

Google’s research blog shows an example of how this feature might work. For instance, you might find a paragraph that says: “This condition is complicated and involves damage to the lungs' air sacs, widespread scarring, changes in the immune cells in the lungs, more production of factors that affect the immune system, and significant changes to the blood vessels in the lungs.”

This condition damages the lungs in two main ways. First, emphysema damages the air sacs in the lungs. Second, fibrosis causes a lot of scarring in the lung tissue. Also, the immune cells in the lungs change, and the body makes more substances that control the immune system. The blood vessels in the lungs change a lot too.

Google explains that this tool helps people understand difficult subjects they find when learning online.

Google said in a blog post, "We want our models to rewrite difficult ideas correctly, without adding mistakes or leaving out important details. The new text should help people understand hard topics while keeping the original information accurate."

Simplify is becoming available for people using iPhones this week.
