Done Doesn't Know It's Done
Most pieces have a great ending. It's just not the last paragraph.
Most pieces have one paragraph too many.
Not the weakest paragraph. The last one.
Writers add it for themselves. It’s the exhale after the work is done. A quiet summary of what just happened. A soft landing. Sex followed by a debrief. “So what that was, was intimacy. We connected emotionally and physically, which research suggests is important for long-term bonding.” (Nobody wants this. Nobody has ever wanted this.)
AI Does It Too. And It’s So Much Worse.
AI does it enthusiastically. Pathologically, even.
It was trained to. Human raters marked responses as “complete” when they had a tidy wrap-up, so models learned that a summarizing conclusion equals a finished piece. Now every AI output ends with some variation of “Ultimately, X matters because Y” or “The takeaway here is...” or the always-popular nothing-sentence that restates the entire piece in case you forgot what you just read.
The phrasing rotates. The move never changes.
Which means if you’re co-writing with AI and not cutting the last paragraph, you’re not just over-explaining. You’re leaving the most recognizable AI fingerprint in the entire piece sitting right where everyone looks last.
Your Reader Already Got There. You Just Don’t Trust Them.
The piece already made its point. The last paragraph just confirms it. Which tells the reader you didn’t trust them to get there on their own.
They noticed. They always notice.
The 30-Second Test That Proves It
Delete your last paragraph. Read the piece again. If it ends stronger, leave it deleted. If something’s genuinely missing, put it back.
Most of the time? It ends stronger.
Because the real ending was almost always the second-to-last paragraph. The last one is you sticking around after the party’s over. Or AI doing what it was rewarded to do. Either way, same problem. Same fix.
The Bow Is for You. The Summary Is for the Model. Neither Is for the Reader.
Writers over-explain because the work felt incomplete without a bow on it. AI over-explains because a committee of human raters told it “complete” looks like a summary. Both are writing for themselves. The reader finished the thought. They’re already standing up to leave.
Let them go.

PS... If this post made you delete your last paragraph, you’re already doing the thing. The next thing: making sure what AI hands back doesn’t quietly sand down the paragraphs you kept. Voice Sync is four prompts, twenty minutes, and it builds a Voiceprint that catches AI smoothing you down in real time. Free. File lands in 30 seconds. The only cost is finding out I was right:
PPS... If this was useful: subscribe, like, restack, the full set. Then open something you wrote this week and delete the last paragraph right now, before you talk yourself out of it. Come back and tell me what happened. That’s the comment I actually want.
