Substack recently launched its AI detector feature in the UI, which is super interesting.Separately, lots of people asked me about interesting local do-it-yourself LLM projects as demos to show what small language models (SLMs) are capable of.Putting one and one together, I thought it would be interesting to show how an AI detector can be implemented. I will also use it as a verifier to train a small language model to produce text that avoids detection. This is a small educational project for studying the limitations of AI detectors and exploring a verifier-based LLM application beyond regular reasoning models trained on math and code.Figure 1: Substack now features a built-in AI detector.So, as mentioned above, the intended goal of this tutorial is to explain how AI detectors work by building (a simple) one.In practice, such a detector can be used to filter out spammy content, but also to potentially improve your personal writing without turning it into AI-generated text. For example, if you wrote a lengthy article and want to improve spelling and grammar, it is tempting (and actually useful) to use a grammar checker to polish it and improve readability. There are different services for that, including general-purpose LLMs like ChatGPT. However, this also runs the risk that these tools turn your writing, even though it’s still your own writing, into something that is then overpolished and now sounds like AI and gets flagged as spammy content.For example, with an AI checker, one could say, “Fix my grammar while ensuring that my text still scores 0% AI-generated.”Anyway, …
