Substack has introduced a new feature that allows readers to estimate the extent to which newsletters are written using artificial intelligence. This tool aims to provide greater transparency about the role of AI in content creation, according to TechCrunch.

The feature reflects growing interest and concern over AI-generated content in digital publishing. By offering readers this insight, Substack is responding to demands for clarity on how much human input versus AI assistance is involved in newsletter production.

For Japanese investors and traders, where AI adoption is accelerating across FX, crypto, and equities markets, tools like this highlight the evolving intersection between technology and content transparency in financial information dissemination.
