Reddit users have developed a sixth sense for generic AI cadence: tidy triads, empty confidence, and zero scars. They downvote it on principle. That does not mean you should write everything from a blank page. It means AI should never be the voice of record.
Use models as a research intern. You remain the editor who has actually done the work.
What AI is good for
Talk Scan is useful here: feed it a subreddit and a topic, then steal the language of real complaints, not the language of a landing page.
The authenticity pass (do this every time)
After the model drafts, delete every sentence you could not defend in a comment thread. Add one number from your own week. Add one mistake. Add one constraint ("this failed for teams under ten people"). Replace "leverage" and "landscape" with the words your users type.
Read the draft out loud. If you would be embarrassed to post it under your real name, it is still AI.
Title lab
Generate ten titles. Keep none of them. Combine the sharpest noun from one with the tension from another. Specific beats clever: "We cut onboarding from 14 days to 3 and lost two enterprise deals" will outperform "Unlocking onboarding excellence."
Post Maker can produce variants in a chosen tone. Treat those variants as clay, not copy.
Comments are the real content
The post gets you into New. The comments keep you in Hot. Draft three replies before you submit: a clarification, a disagreement you invite, and a question that is not "thoughts?" When people answer, reply with more detail than they asked for.
Detection is social, not just technical
Even if a classifier misses you, a regular will reply "this is ChatGPT." Once that sticks, the thread is radioactive. The fix is not better prompting. The fix is putting your fingerprints on the work: screenshots, dates, tradeoffs, and a willingness to be wrong in public.
