Google has launched a new AI tool for Substack creators. The tool automatically generates short summaries of newsletters. These summaries appear at the top of each post for subscribers. The goal is to help readers quickly understand what the newsletter covers.

The feature uses Google’s latest artificial intelligence technology. It reads the full newsletter and picks out the key points. Then it writes a clear and simple summary. Creators do not need to do anything extra. The AI works in the background once it is turned on.
Substack writers can choose whether to use the tool. They can review the summary before it goes live. If they do not like it, they can edit or remove it. This gives them full control over their content.
Many creators spend hours writing detailed posts. Some readers may not have time to read everything. The AI summary helps busy subscribers get the main ideas fast. It also makes long newsletters more accessible.
Google says this tool is part of its effort to support independent publishers. Substack hosts millions of writers around the world. Most of them work alone without big teams. Tools like this could save them time and reach more readers.
The feature is now available to all Substack users who link their accounts with Google. It works on both desktop and mobile devices. Early feedback from testers has been positive. They say it improves reader engagement without changing their voice.

Google plans to keep improving the AI based on user input. Future updates may include support for multiple languages and custom tone options. For now, the focus is on making summaries accurate and helpful.
