AI won't do your writing for you — nor should it. But it will do what a good writing group does: throw ideas back, spot the boring parts, and show you where you could be more precise. The gap between generic output and genuinely useful help is the prompt.
We use these 20 constantly at Promptigo, across blog posts, essays, and fiction. They work in ChatGPT, Claude, Gemini, or any assistant. Copy them, replace the brackets, and iterate in the same thread.
Ideas and angles: before you draft
1. The angle generator.
I want to write about [topic] for [audience]. My take so far is [one-sentence take]. Give me 7 distinct angles on this topic — each with a working title and the one surprising idea it hinges on. Flag the angle most likely to be shared.
Most writing about a topic repeats the same angle. This forces divergence before you commit.
2. Hook stress test. A weaker hook kills an essay before it starts. Try this before you draft:
Here are 3 possible opening lines for an essay about [topic]: [lines]. For each, tell me: does it create a question in the reader's mind, does it promise something worth reading for, and would it stop a scroller. Pick the winner and rewrite it 2 ways.
For a full hook workshop, our Story Hook for a Dry Intro prompt turns flat openings into curiosity-driven ones.
3. The thesis sharpener. Especially for essays — our Essay Thesis Builder does this formally, but the manual version is:
My current thesis is [thesis]. Give me 3 stronger versions: one more specific, one more arguable, and one more surprising. Then tell me which one forces me to leave something important out — that's usually the sharpest.
A good thesis excludes. The prompt that makes you choose what not to argue is the one that clarifies your point.
4. Scope check.
Here's my outline: [outline]. Tell me which section is trying to be its own essay, which section is filler, and what question a skeptical reader will ask that I haven't answered. Suggest a cut and an addition.
Writing fails more often from trying to do too much than too little. This finds the essay inside the essay.
Structure: building the skeleton
5. The blog-post scaffold. Our Blog Post from Outline prompt does this from bullet points to draft, but the planning version is:
Turn this outline into a blog post structure with: a hook that names the reader's problem, 3–5 section headings that each make a claim (not a topic), one concrete example or data point per section, and a closing that tells the reader what to do next. Keep headings under 6 words.
Headings that make claims ("Show, Don't Tell Is a Revision Tool") beat headings that name topics ("Show vs Tell"). Claims move the reader forward.
6. The story shape finder.
I have these beats: [events / points in order]. Arrange them into the structure that creates the most tension: chronological, reverse, braided, or problem-solution. Explain the tension mechanism for each arrangement and recommend one.
Structure is tension management. This treats ordering as a strategic choice, not a default.
7. The transition audit.
Here's my draft: [draft]. For each paragraph break, state the relationship between paragraphs — continuation, contrast, cause-effect, or example — and flag any break where the relationship is unclear. Suggest the missing transition sentence.
Rough drafts feel disjointed not because ideas are bad but because transitions are implicit. Making them explicit fixes flow without rewriting everything.
8. The "so what" test.
For each section in my draft, answer: what does the reader do or believe differently after reading this? Flag any section where the answer is "nothing" or "they know a fact." Suggest what that section needs to earn its place.
Sections that teach a fact without changing a belief are trivia. This prompt turns them into arguments.
Drafting: getting words down
9. The constraints draft. Constraints produce better first drafts than open-ended asks:
Write a rough draft of [section] in 180 words. Constraints: every paragraph must start with a concrete image or action, no sentence over 20 words, and the last sentence must refer back to the opening image.
You won't keep this draft. You'll keep the sentences it forced you to write that you wouldn't have otherwise. Iterate from there.
10. The example generator.
My point is [claim]. Give me 3 concrete examples that illustrate it — one from everyday life, one from a well-known story or historical event, and one counterintuitive. Each example in 2 sentences max.
Specificity is the fastest way to make writing memorable. This prompt manufactures it.
11. Sensory upgrade. Pair with our Show Don't Tell Rewriter:
Rewrite this paragraph so at least one detail appeals to each of sound, touch, and smell — without adding new events: [paragraph]. Keep the paragraph length within 20%.
Most drafts are visual-only. Adding other senses makes a scene feel lived-in.
12. The voice calibrator.
Here's a paragraph I like and one I don't: [likes] / [dislikes]. Tell me the 4 most measurable differences between them — sentence length, word choice, rhythm, abstraction level — and give me a rule I can follow to write more like the first one.
This is more useful than "write in my voice" because it gives you a rule you can apply yourself, not just a one-off rewrite.
Revision: tightening and clarifying
13. The 10% cut. Our most-used editing prompt:
Cut 10% of the words in this passage without losing any information or voice. Show before and after word counts and list what you cut: filler, repetition, hedging, or throat-clearing.
Use Tighten Wordy Drafts for a structured version that tracks cuts by category.
14. The complexity simplifier. For passages where you're explaining something hard:
Simplify this passage for a smart reader who is new to the topic: [passage]. Replace jargon with plain language, break sentences over 24 words into two, and use an analogy for the hardest idea. Then tell me if any simplification lost an important nuance.
Our Simplify Complex Writing prompt does this with an explicit "don't lose the nuance" guardrail — use it when the topic is technical.
15. The three-pass revision. When a draft is decent but not sharp, run our Three-Pass Improvement prompt:
It does clarity, then voice, then tightening in sequence — three separate passes so each job gets full attention. Better than "make this better" because it doesn't try to do everything at once.
Manual version:
Pass 1: Flag every sentence over 22 words and every hedge word (perhaps, somewhat, relatively, very). Pass 2: Flag every place where word choice is abstract when a concrete noun or verb would work. Pass 3: Cut what remains that repeats a prior point.
16. The repetition detector.
Here's my draft: [draft]. List every idea, phrase, or example that appears more than once, and tell me if each repetition is strategic (reinforcement) or accidental (filler). Suggest which accidental repetitions to cut and which strategic ones to make more deliberate.
Writers repeat themselves without noticing. This finds the echoes your eye skips.
Feedback: before readers see it
17. The hook and promise check. Use Story Hook for a Dry Intro on your opening, then test the whole piece:
Here's my essay: [essay]. As a reader who found this via search, answer: What did the title promise? Does the first 200 words deliver on that promise? Where did you first consider bouncing?
Bounce-point feedback is brutal and specific — exactly what you need before publishing.
18. Emotion without labels. Borrowed from our character development guide because it applies to any writing that conveys feeling:
Find every emotion word in this passage — sad, angry, nervous, relieved, excited — and replace each with behavior, body language, or sensory detail. Keep length within 10% of the original.
This works on essays and blog posts too, not just fiction. "The data is concerning" is telling. "The churn line on the graph doubled between March and May" lets the reader feel it.
19. The skeptical reader. Our Beta Reader Simulation prompt does this as a structured review, but the targeted version is:
Read this as a skeptical expert on [topic]: [draft]. For each claim, tell me: is it obviously true, plausibly true but needing evidence, or dubious. For every dubious or plausibly-true claim, say what evidence would satisfy you.
This catches the places where you're asserting when you should be demonstrating. Essential before publishing anything advice-driven.
20. The read-aloud test.
Here's my draft: [draft]. Flag every sentence that would be awkward to read aloud — too long, tongue-twisting, or rhythmically monotonous. Suggest a read-aloud-friendly rewrite for each flagged sentence.
If you actually do read it aloud after, you'll catch 80% of these yourself. The prompt catches the rest.
How to make these pay off
Three habits:
- Iterate in thread, not from scratch. "Make option 2 more concrete" works because the AI remembers context. Restarting loses that and you get generic output again.
- Keep the constraint, replace the content. Once a prompt works with one topic, reuse the same structure — the constraints are the value, not the wording.
- You decide, AI proposes. Every prompt here asks for options or analysis. Your job is choosing. The writers who get the most from AI are the ones who stay opinionated.
Start where your draft is stuck. If it's at the idea stage, grab prompts 1–4. If you have words that aren't landing, jump to 13–16. And if you're ready for structured templates, the library has them free to copy: Blog Post from Outline, Tighten Wordy Drafts, Simplify Complex Writing, and Three-Pass Improvement in the Promptigo library.
