If you want to make your writing appear non-AI generated, the easiest way is to write it yourself. No typos necessary.

I’m sure with enough cajoling you can make the LLM spit out a technical blog post that isn’t discernibly slop - wanton emoji usage, clichés, self-aggrandizement, relentlessly chipper tone, short “punchy” paragraphs, an absence of depth, “it’s not just X—it’s a completely new Y” - but it must be at least a little tricky what with how often people don’t bother.

[ChatGPT, insert a complaint about how people need to ram LLMs into every discussion no matter how irrelevant here.]
