How to use AI to write content that sounds like you
Everybody can spot AI writing now. The tidy sentences, the balanced take that offends nobody, the summary at the end that repeats what you just read. It's a smell, and readers back away from it.
The usual advice is to write a better prompt. That helps a bit, and it isn't the real problem.
The real problem is that it knows nothing about you
An AI with an empty text box has no choice but to write the average of everything it's read. Average is exactly what you don't want, because average is what your reader has already seen a hundred times.
So the fix isn't asking better. It's giving it something real to work from.
Give it your own material
Feed it your best posts and tell it to notice how you actually write. Your sentence length, the words you use, whether you swear, whether you tell stories or make points. Then ask it to write in that.
This works far better than describing your voice, because describing your voice is hard and showing it is easy.
Give it real information, not just a topic
This is the bigger one. "Write me a post about LinkedIn growth" produces sludge, because there's nothing in it. "Here are four posts that recently beat their author's average in my space, here's what they had in common, now write my version with this story of mine" produces something worth posting.
The difference is evidence. With evidence it's writing about something. Without it, it's generating text.
Use the AI you already pay for
You almost certainly already pay for Claude or ChatGPT. You don't need another writing app with a weaker model bolted on, you need your existing AI to be able to see your real data.
That's what Kadenza is for. It connects to the AI you already use so it can read what's working in your space and your own results, and write from that instead of from nothing.
Always do the last pass yourself
Read it out loud before posting. Cut the summary at the end, cut any sentence that could have come from anyone, and put one thing back in that only you would say.
That last pass takes four minutes and it's the whole difference between your post and content.
