AI Writing Mistakes

AI writing fails in predictable ways. Once you know the common mistakes, you can catch them quickly and rewrite with purpose. This page lists the ones that appear most often and shows what to do instead.

Recycled transitions

AI loves tidy connectors: “in addition,” “moreover,” “furthermore,” “additionally,” “on the other hand.” These words are not wrong, but they appear far more often in machine text than in real speech.

People usually connect ideas with simpler words or with no connector at all. A short sentence or a natural shift is enough.

Fix: Delete the formal transition. Start the next sentence directly. If you need a link, use “and,” “but,” “also,” or just let the ideas sit next to each other.

Filler intensifiers

Words like “very,” “really,” “extremely,” “highly,” and “incredibly” show up constantly in AI drafts. They try to add force but usually weaken the sentence.

Strong writing chooses a precise word instead of padding a weak one.

Fix: Remove the intensifier. If the sentence feels flat, replace the main word with something more exact. “Very important” becomes “central.” “Really useful” becomes “practical.”

Uniform sentence rhythm

AI tends to produce sentences of roughly the same length. The result is a steady, almost musical beat that feels manufactured.

Human writing mixes short and long without planning it. A three-word sentence can land hard. A longer one can carry a full thought.

Fix: Read the paragraph out loud. Whenever three or four sentences in a row feel the same length, break one. Make one shorter. Let another stretch a little. The variation itself makes the text feel alive.

Overly formal tone

AI defaults to a polite, slightly distant register. It avoids contractions. It chooses the longer word when a shorter one would work. The result sounds careful rather than spoken.

Most people write closer to how they talk, especially in blog posts and practical guides.

Fix: Add contractions where they feel natural. Prefer the shorter word. Read the sentence and ask whether you would actually say it that way to a colleague.

Missing personal viewpoint

AI has no real experience to draw from. It stays general. It rarely takes a clear side or shares a small, concrete observation.

Readers notice the absence of a person behind the words.

Fix: Add one short, specific detail that only you could have written. A reaction. A memory. A quiet observation. It does not need to be dramatic. Even one real moment changes the feel of a whole section.

Perfect paragraph shapes

AI often builds neat blocks of three or four sentences that all serve the same idea and end cleanly. Real writing is messier. Some paragraphs are short. Some contain an aside. Some end abruptly because the thought is finished.

Fix: Break a few of the tidy blocks. Let one paragraph be only two sentences. Move a side thought into its own short line. Allow the structure to follow the thinking instead of forcing every idea into the same container.

Safe, balanced opinions

AI rarely commits. It presents both sides, softens strong statements, and avoids clear preference. The text stays agreeable but forgettable.

Human writing can be direct. It can lean. It can say something is better without listing every possible counterpoint.

Fix: Decide what you actually think and say it. You can still be fair, but you do not need to neutralize every claim.

Empty openings and closings

Many AI drafts begin with broad statements about “today’s world” or “the importance of” and end with tidy summaries that restate what was already said. These bookends feel automatic.

Fix: Start closer to the real point. End when the useful part is finished. A short, concrete last line often works better than a formal conclusion.

How to use this list

You do not need to hunt for every single pattern in one pass. Read the draft once for the big problems: rhythm, tone, and missing personal presence. Then do a second pass for the smaller ones: transitions, intensifiers, and formal words.

The goal is not to make the text imperfect on purpose. The goal is to remove the parts that only exist because the model averages what people usually write. What remains should sound like something a real person would say.

When the common mistakes are gone, the writing starts to feel human even if the original draft came from AI.
