Style Prompting
The same information can land brilliantly or fall flat depending on how it’s delivered. Style Prompting separates what you want the AI to say from how you want it said — giving you explicit control over tone, formality, voice, and every dimension of written expression.
Introduced: Style Prompting was published in 2023 by Lu et al. The research identified a persistent gap in prompt engineering: users could tell models what to write, but had limited systematic control over how it sounded. Lu et al. demonstrated that explicitly specifying style dimensions — formality, complexity, tone, and vocabulary level — produced outputs that were measurably more aligned with user intent than prompts that focused only on content requirements.
Modern LLM Status: Style Prompting remains a still active and integral technique in everyday prompt engineering. As language models have grown more capable, their default outputs have also become more “middle-of-the-road” in voice — competent but generic. Style instructions counteract this tendency by steering the model toward a specific register, making the technique more valuable than ever for anyone who needs content that sounds like it was written by a particular person, for a particular audience, or in a particular context.
Voice Control for AI
Every piece of writing has two layers: the content (the information, arguments, or ideas) and the style (the way those ideas are expressed). A medical diagnosis and a patient-friendly explanation contain the same facts, but the style is radically different. Style Prompting makes this distinction explicit in your prompts.
The technique works by specifying style dimensions independently of content. Instead of hoping the model infers the right tone from context, you declare it outright. This means you can take the same content request — “explain how encryption works” — and produce a LinkedIn post, a children’s book explanation, a graduate textbook paragraph, or a stand-up comedy bit, simply by changing the style parameters.
Think of it like a mixing board in a recording studio. The song (content) stays the same, but you can adjust the bass, treble, reverb, and volume independently to produce a completely different listening experience. Style Prompting gives you separate knobs for formality, complexity, tone, perspective, vocabulary, and structure.
Formality: Casual conversation to academic register. Controls contractions, slang, sentence structure, and professional conventions.
Complexity: Simple explanations to expert-level analysis. Adjusts depth of reasoning, assumed knowledge, and technical detail.
Tone: Warm and encouraging to direct and authoritative. Sets the emotional texture of the writing.
Perspective: First person, second person, or third person. Determines the relationship between writer and reader.
Vocabulary: Plain language to domain-specific jargon. Controls word choice and terminology level.
Structure: Free-flowing prose to rigid frameworks. Determines paragraph length, use of headers, bullet points, and organizational patterns.
The Style Prompting Process
Four stages from content request to polished, voice-matched output
Define Your Content Requirements
Start with a clear statement of what information, arguments, or ideas the output should contain. This is the “what” layer — the substance that would remain the same regardless of how it’s expressed. Be specific about the topic, scope, and any facts or points that must be included.
“Explain the benefits and risks of cloud computing for small businesses, covering cost savings, scalability, security concerns, and vendor lock-in.”
Choose Your Style Parameters
Decide which style dimensions matter for your audience and context. You don’t need to specify all six — focus on the dimensions that will have the biggest impact. A blog post for beginners might need casual formality, simple complexity, and warm tone. A board presentation might need formal register, moderate complexity, and authoritative tone.
Target: Non-technical small business owners reading a blog. Parameters: conversational tone, plain vocabulary, second-person perspective, short paragraphs with analogies.
Write the Style Instruction
Combine your content requirements with explicit style directions. The key is being specific and concrete about style rather than vague. Instead of “write it simply,” say “use everyday language that a shop owner with no tech background would understand, avoid all acronyms, and explain each concept through a real-world analogy.”
“Write this as a friendly, conversational blog post for non-technical small business owners. Use ‘you’ and ‘your’ throughout. Explain each concept with a real-world analogy (like renting vs. buying an office). Keep paragraphs to 2–3 sentences. Avoid all jargon and acronyms.”
Receive Styled Output
The model produces content that matches both your information requirements and your style specifications. The output should feel like it was written specifically for your target audience, in the voice you described. If the style isn’t quite right, iterate by adjusting specific dimensions rather than rewriting the entire prompt.
An approachable blog post that compares cloud storage to renting a storage unit, explains scalability as “only paying for the space you actually use,” and addresses security concerns without triggering anxiety — all in a tone that feels like helpful advice from a knowledgeable friend.

How explicit style instructions transform generic outputs into audience-matched content
No Style Instruction
Write about cloud computing for businesses.
Cloud computing is a technology that enables businesses to access computing resources over the internet. It offers several advantages including cost efficiency, scalability, and flexibility. Organizations can leverage cloud infrastructure to reduce capital expenditure while maintaining robust IT capabilities. However, considerations around data security and vendor dependency should be evaluated…
With Style Instruction
Write about cloud computing in a conversational blog style for non-technical managers. Use “you” throughout, include analogies instead of jargon, keep paragraphs short, and maintain an encouraging but honest tone.
Think of cloud computing like renting an apartment instead of buying a house. You get all the space you need without the massive upfront cost — and if your team grows, you can upgrade to a bigger place without selling anything first.
The best part? You only pay for what you actually use. But here’s the honest truth: you’re trusting your landlord with your keys…
Practice Responsible AI
Always verify AI-generated content before use. AI systems can produce confident but incorrect responses. When using AI professionally, transparent disclosure is both best practice and increasingly a legal requirement.
48 US states now require AI transparency in key areas. Critical thinking remains your strongest tool against misinformation.
Style Prompting in Action
See how style parameters transform the same content for different audiences
“Write a summary of our Q3 results in a formal executive tone suitable for the annual report. Use third-person perspective, precise financial language, and structured paragraphs with topic sentences. Maintain a measured, authoritative voice throughout.”
Output: “The organization achieved a 12% year-over-year revenue increase in the third quarter, driven primarily by expansion in the enterprise segment. Operating margins improved to 23.4%, reflecting disciplined cost management and favorable product mix. Management anticipates sustained momentum entering the fourth quarter.”
“Now rewrite this as a casual Slack message from the CEO to the whole company. Use first-person plural, keep it upbeat but genuine, use everyday language, and make it feel like good news shared over coffee.”
Output: “Hey team! Just wanted to share some great news — we grew 12% this quarter compared to last year, and our enterprise deals were the big driver. We’re running leaner too (margins up to 23.4%), which means we’re not just growing, we’re growing smart. Feeling really good about where we’re heading into Q4. Thanks for making this happen!”
“Explain how HTTPS works. Use precise technical terminology appropriate for a software engineering audience. Include protocol-level details, assume knowledge of TCP/IP, and write in a concise, reference-manual style.”
Output: “HTTPS operates by layering HTTP over TLS (Transport Layer Security). During the TLS handshake, the client and server negotiate a cipher suite, the server presents its X.509 certificate for authentication, and both parties derive symmetric session keys via Diffie-Hellman key exchange. Subsequent HTTP payloads are encrypted using the negotiated symmetric cipher, ensuring confidentiality and integrity at the transport layer.”
“Now explain HTTPS for someone who has never heard of it. Use a storytelling approach with a real-world analogy. Write as if explaining to a curious 14-year-old. Avoid all technical terms — if you must introduce one, explain it immediately in plain language. Keep the tone friendly and encouraging.”
Output: “Imagine you’re passing a note to your friend in class, but you don’t want anyone else to read it. HTTPS is like writing that note in a secret code that only you and your friend know. When you visit a website with HTTPS (you’ll see a little padlock in your browser), your computer and the website quickly agree on a secret code before they start talking. After that, everything they send back and forth is scrambled — so even if someone intercepts it, all they see is gibberish.”
“Write a product announcement for our new project management tool. Apply these style parameters:
Formality: Professional but approachable — not stiff corporate, not startup casual
Tone: Confident and excited, without being salesy or hyperbolic
Complexity: Accessible to non-technical users but not condescending
Perspective: First-person plural (‘we’) for the company, second-person (‘you’) for the reader
Vocabulary: Plain English, replace jargon with benefits (not ‘integrations’ but ‘works with your existing tools’)
Structure: Short paragraphs, one key benefit per paragraph, bold the main takeaway of each section”
The output matches all six dimensions simultaneously: it reads like a well-crafted company blog post that feels human and enthusiastic without crossing into marketing clichés. Each paragraph leads with a bolded benefit, uses “we” and “you” naturally, and explains features in terms of what they mean for the reader — not what they are technically. The combined effect is a cohesive voice that would take a human writer several drafts to achieve.
When to Use Style Prompting
Best for tasks where how you say it matters as much as what you say
Perfect For
When the same information needs to reach different audiences — executives, engineers, customers, or students — style parameters let you tailor the delivery without changing the substance.
Maintaining a consistent tone across dozens of pieces of content is hard for human teams. Style Prompting lets you encode brand voice as a reusable set of style parameters.
Transforming a whitepaper into a blog post, a blog post into a tweet thread, or a presentation into a newsletter — same core content, completely different style needs.
Adjusting complexity and vocabulary makes content accessible to readers with different literacy levels, language backgrounds, or domain expertise — without dumbing down the ideas.
Skip It When
“What is the capital of France?” doesn’t benefit from style instructions — the answer is the same regardless of tone or formality level.
When you need working code, style parameters add unnecessary complexity. Code has its own conventions that are better addressed through code-specific prompting techniques.
If you’re struggling to get the right information, focus on content accuracy first. Style instructions work best when layered onto a prompt that already produces correct, complete content.

Where Style Prompting Fits
Style Prompting controls the delivery dimension of zero-shot prompting
Style Prompting is a fundamental dimension that enhances almost every other technique. It works as a standalone approach for simple content tasks, but its real power emerges when combined with frameworks like COSTAR (which includes style as an explicit parameter) or Role Prompting (where the persona carries an implied style that you can fine-tune with explicit style instructions).
