Google is adding a new "Simplify" tool to its app for iPhones. This tool uses AI to make difficult or technical writing on websites easier to understand while you stay on the page.

Simplify uses a method from Google Research to make prompts better. It uses Gemini to make difficult text easier to understand, but it keeps the main points. Google tested this and found that the simpler text helped people understand and remember the original information better.

Google probably hopes people will keep using its tools and services for help with hard topics by offering a feature like Simplify, instead of using popular tools from other companies, like OpenAI’s ChatGPT.

To use Simplify, choose any text on a website you are looking at in the Google app, and then tap the "Simplify" symbol. A clearer version of the text will appear to help you understand the information and continue reading easily.

Google’s research blog shows an example of what this feature could be like. For example, you might see a sentence that says: “This condition causes complicated lung damage, including destroying lung tissue, widespread scarring, changes in lung immune cells, more factors that affect the immune system, and important changes to blood vessels in the lungs.”

This serious illness harms the lungs in two main ways: emphysema, which damages the small air sacs, and fibrosis, which 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 also change a lot.

Google explains that the goal of the feature is to help people understand difficult subjects they might find when learning something new 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 rewritten text should help people understand hard topics, while keeping the original meaning."

Simplify is becoming available to people using iOS this week.
