Substack Introduces AI Detection Tool for Newsletters

Substack has launched a new feature that helps readers identify whether a newsletter or post was written by a person or generated with AI. 

The new tool aims to improve transparency as AI-assisted writing becomes more common across online publishing.

Instead of restricting AI use, Substack wants to give readers more information about the content they consume.

How the AI Detection Tool Works

The new feature uses AI detection technology to estimate how much of a post was written by a human and how much may have been generated by AI.

It can analyze:

• Newsletters
• Posts
• Comments
• Replies

The tool is available for content that meets a minimum character requirement within the Substack app.

More Transparency for Readers and Writers

Substack is also introducing an optional AI disclosure feature. 

Writers can explain how AI was used during the writing process, helping readers better understand how the content was created.

The platform says the goal is not to punish creators who use AI, but to encourage openness and build trust between writers and their audiences.

Why This Matters

As AI-generated content becomes more common, readers are increasingly looking for ways to know whether what they’re reading is original or AI-assisted. 

With AI detection and optional disclosure features, Substack aims to improve transparency while encouraging responsible use of AI. 

Conclusion

The new Substack AI detection tool gives readers greater transparency and helps writers clearly disclose their use of AI. 

The update reflects a growing trend toward making AI-generated content easier to identify across online platforms.
