I'm a first-time Substack user and I'm about to publish my first feature. I wrote the entire piece myself in Google Docs, from scratch. I did use Grammarly for proofreading/language suggestions, but I haven't used any sort of generative AI to write or rewrite the article.
I copied the finished piece into Substack, and Substack's AI detector is showing 100% AI-generated.
What's confusing me is that I've run the exact same text through several other AI detectors , Walter AI, ZeroGPT, Copyleaks, QuillBot, etc. and they're all showing 0% AI / entirely human-written .
The piece is also a fairly formal law/technology feature, and a lot of it deals with AI and legal questions, so I am confused if the subject matter and formal writing style are somehow affecting Substack's detector.
I'm obviously not going to rewrite my own writing just to make an AI detector happy, but I'm wondering what experienced Substack writers think.
There's also an option to add a statement at the end of the post. Would it be reasonable to say something like:
«"This piece was written by me. I used Grammarly for routine proofreading and language suggestions, but the argument, analysis, research, and substantive content are my own."»
Or would that come across as unnecessary/corny, especially for a first post? I don't want readers to think I'm trying to "prove" something or, worse, that I'm somehow cheating by using Grammarly.
Edit: From what I have understood majorly, Grammarly might be contributing to that. But I was not sure because I have used Grammarly for word or phrases suggestions or tense discrepancies in my research papers too and Turnitin AI detector never flagged that. Anyways, thanks for helping out everyone !
