5 Ways to Fix AI-Sounding Writing | Remove the "AI Feel" to Get Your Content Read to the End

I write articles using AI. But I have never published anything "exactly as the AI wrote it."

When I read the output, I usually feel it's "thin." It's polished, but it doesn't sound like anyone. The content is 90% good, but the "AI-ness" of the first three lines prevents it from being read to the end. That's where you're losing out.

In fact, I have deleted articles I finished writing right before hitting the publish button many times. The reason is always the same: "It sounds a bit like AI." No one told me that. I read it myself, thought that, and stopped.

There are only five fixes I use to erase that "thinness." Today, I'm writing them all down below, along with copy-pasteable prompts. By the time you finish reading, your output should be much closer to something written by a human.

To begin with, why does AI writing sound "AI-like"?

The reason is simple: AI chooses the safest expressions.

AI reads vast amounts of text and writes based on the probability of "what word is likely to come next in this context." Therefore, the output is the most average, most common phrasing. It's like an honor student's answer that won't lose points no matter who reads it.

What is the result? The sentence endings are all the same. Modifiers are piled on. It becomes a smooth, featureless text that you feel like you've read somewhere before. There are no mistakes. But there is no body heat. The true nature of what people perceive as "AI-like" is this "safeness to avoid losing points."

That's all there is to it. If so, you can erase it by shifting it slightly with human hands. I'll list five ways. ① to ③ are about tweaking the sentences themselves, and ④ to ⑤ are about how to give instructions to the AI. Here come the effective ones.

Fixing Tip ①: Vary the sentence endings (the mechanical smell disappears immediately)

The most AI-like aspect is the sentence endings. The moment "is," "is," and "is" line up, the machine's face appears. Readers sense the mechanical nature through this rhythm before they even grasp the content. There is one rule: do not repeat the same sentence ending three times.

Use definitive statements, questions, and noun-ending phrases. Mixing them creates rhythm.

Fixing Tip ②: Cut out NG words and redundant expressions

AI piles on words. Words like "it is possible to," "very," and "extremely" get mixed in in large quantities before you know it. Most of them can be cut.

"It is possible to" becomes "can." "Very convenient" becomes "convenient." The meaning doesn't change by a millimeter. In fact, it becomes tighter. Express strength through facts, not adverbs. The guideline is: cut 20% of the total while maintaining the meaning.

次の文章から冗長表現を削ってください。「することができます」は「できます」に、「非常に/とても」などの強調語は本当に必要か検討して削減。意味を変えずに、全体の文字数を2割減らしてください。

Tip 3 for fixing: Keep it to one idea per sentence

AI tends to pack too much into a single sentence. It connects clauses endlessly, and by the time the reader finishes, they've lost track of the subject. It's the kind of thing that tires out a reader's brain.

The rule is: one piece of information per sentence. If you find a long sentence, break it up with a period. That alone makes it much easier to read.

次の文章を、一文一義に直してください。1つの文に情報を詰め込みすぎている箇所は、複数の短い文に分割。1文が長いと感じたら句点で区切ってください。

Tip 4 for fixing: Paste a writing sample and have it imitate it (this is the real deal)

Everything up to this point has been about fixing what has already been generated. Next is the trick of steering it at the generation stage. And this is the most effective one.

Even if you tell an AI to "write frankly," it will only return the safe, generic version of frankness that it thinks you want. So, show it the real thing. It could be your own past writing, a passage from a writer you like, anything. Paste 1-2 paragraphs and tell it, "Use this tone." The accuracy of the imitation will be vastly better than explaining it in words.

(Paste 2-3 paragraphs of your own writing sample here)

Tip 5 for fixing: Have the AI critique your own writing before fixing it

The last one is a combination technique. Have the same AI check the text it wrote as if it were "someone else's writing." People are lenient with their own writing. But AI will point out flaws without mercy.

If you prompt it with "Point out the AI-sounding parts," it will find monotonous sentence endings and redundant expressions on its own. Don't have it fix them yet. Just have it point them out first, and then fix them based on that. It's a self-directed review, but it really works.

次の文章を、プロの編集者として添削してください。「AIが書いたと感じる箇所」を具体的に指摘し、その理由と修正案をセットで提示。指摘は最低5つ。まずは指摘だけ、直しは後で。

The "AI feel" is not a matter of talent or sense. It is simply a matter of whether or not you add one line of instruction. Start with the sentence-ending variation in (1), and try adding it when you prompt the AI next. The look of the output should change.
