Prompting

7 Prompting Mistakes That Make Your AI Output Sound Generic

Vague prompts produce forgettable output. Here are seven common habits that flatten results, each paired with the weak version and a sharper rewrite.

7 Prompting Mistakes That Make Your AI Output Sound Generic

You type a prompt. Something comes back. It's clean, competent, and completely forgettable, the written equivalent of beige paint. Most people blame the tool at that point. Usually the problem sits upstream, in a prompt that never said what "good" looks like.

Generic output has a small number of causes, and each one has a boring, repeatable fix. Here are the seven habits that flatten results most often, with the weak version and the corrected version of each.

1. You name a topic instead of a task

"Write about our pricing" is a topic. Faced with a topic, the safest possible response is a summary, so that is what you get.

Weak:

Write about our new pricing page.

Corrected:

Draft three versions of the pricing page intro, about 60 words each, for a small business owner comparing us with two competitors. Lead with the cost of switching, not the feature list. Avoid the word "solution".

The fix is a verb. Draft, compare, rewrite, outline, cut, rank, summarise for a specific reader. A task forces a decision. A topic invites a shrug.

2. You leave the audience blank

If you don't say who is reading, you get the average of everyone, which is nobody. Audience detail changes vocabulary, examples, and how much you bother to explain.

Weak:

Explain our service to customers.

Corrected:

Explain our service to a 45-year-old office manager who has never bought software before and is mainly worried about setup time. Assume no technical vocabulary. Two paragraphs.

Role, prior knowledge, and what the reader is anxious about. One sentence of that is usually enough to shift the whole draft.

3. You skip the shape

"Write a blog post" is not a format. Without length and structure, you get the default: a throat-clearing intro, a few loose sections, a tidy summary that adds nothing.

Weak:

Write a blog post about remote work.

Corrected:

Write a 600-word post for team leads. Short intro, three sections with h2 headings, one bulleted list, and a closing paragraph that gives a single action. No heading longer than six words.

Useful shape constraints to name:

  • Length: "about 600 words", "no more than 120 words per section"
  • Format: numbered steps, a table, one paragraph plus a list
  • Structure: how many sections and what each one covers
  • Language: plain wording, short sentences, define any jargon you use
  • Ending: one recommendation, one question, or stop cleanly with no summary

4. You describe tone with adjectives

"Professional but friendly" means something different to everyone. So does "conversational", "punchy", and "authoritative". Adjectives are the least useful instructions you can give, because they are the hardest to act on.

Weak:

Make it sound warm and human.

Corrected:

Match this rhythm: short sentences, contractions, first person, no exclamation marks, no sentence longer than 20 words. Here are two paragraphs I wrote that sound right: [paste them].

A sample settles every argument that an adjective starts. You don't need your own writing to do this. Paste a paragraph you admire and name what to borrow: sentence length, how it opens, how formal it stays, whether it uses examples or claims.

5. You never say what to leave out

Exclusions do more work than instructions. Without them you get the standard padding: a warm-up sentence, the question repeated back to you, the phrase "it's important to note", and a closing paragraph that says what the piece already said.

Weak:

Improve this email.

Corrected:

Tighten this email to 90 words. Keep the deadline and the link. Cut the apology, the three adjectives in the first line, and any sentence that repeats the one before it. Do not add new claims or new offers.

Keep a short list of bans you reuse: no hedging, no rhetorical questions, no opening with a greeting, no adverbs doing work a verb should do. Paste the list at the end of prompts for anything you'll publish.

6. You stack eight jobs into one prompt

Ask for a launch plan, an email sequence, social posts, landing page copy, and a press release in one go, and every piece gets a fraction of the attention. Then you spend twenty minutes untangling the mess.

Work in passes instead:

  1. Ask for an outline only. Number the sections and say what each one argues.
  2. Fix anything wrong in the outline. This is the cheapest moment to change direction.
  3. Expand one section at a time, referring back to the outline.
  4. Do a final pass on the whole thing, asking only for cuts and tightening.

Staying in the same conversation matters. Earlier decisions carry forward, so you don't have to repeat the audience and format every time. One useful line to add at the top: "If anything is unclear, ask me up to three questions before you start."

7. You say "make it better" instead of naming the problem

If you can't say what's wrong, neither can the rewrite. Vague revision requests produce reshuffled versions of the same draft, which is why a fifth round of "make it better" feels like the first.

Weak:

This isn't quite right. Make it better.

Corrected:

Rewrite paragraph two so the main point is the first sentence. Replace the abstract claim about efficiency with one concrete example of what changes for the reader. Leave everything else exactly as it is.

Pointing at a problem counts, even without a diagnosis. "The middle section drags." "The ending reads like a summary." "This doesn't sound like us." Then say where to look and what to keep, so the good parts survive the rewrite.

The two-minute habit that prevents most of this

Before you send a prompt, read it back and check four things: the task verb, the audience, the shape, and the stop-doing list. If any one is missing, add a sentence. That single habit removes most of the blandness you'd otherwise spend three rounds trying to fix.

Then keep what works. Save your prompts in a plain text file, grouped by job, with a line at the top about what each one is for. Next time, start from the saved version and change only what's different about today's task.

And when something still comes back flat, resist the urge to rewrite the whole prompt. Change one instruction, look at what moved, and keep the change if it helped. Prompting is not a knack you either have or don't. It's a short list of details you remember to include.
