Tone & Voice Control

Adjectives don't work. Comparisons and examples do.

Hiring signal: What changes when you use this: you can match any brand voice or formality level by giving the AI the right context and examples — instead of getting generic 'professional' tone every time.

Iterate on tone when the first attempt doesn't match

The Problem

"Make it professional." "Make it casual." "Make it friendly but authoritative." These are the most common tone instructions in prompts, and they're almost useless. Every person's definition of "professional" is different. The AI's definition of "casual" might mean adding an emoji. Yours might mean using contractions and shorter sentences.

Tone control is one of the most valuable skills in AI-assisted writing — but only if you know how to communicate tone in a way the AI actually understands.

Three Ways to Control Tone (That Actually Work)

1. Comparisons, Not Adjectives

Instead of adjectives, use comparisons the AI can anchor on:

Don't say	Say
"Professional"	"Like a McKinsey consultant presenting to a CEO"
"Casual"	"Like texting a smart coworker"
"Friendly"	"Like a knowledgeable barista explaining the menu"
"Authoritative"	"Like a senior engineer reviewing a junior's code"
"Persuasive"	"Like a startup founder pitching an investor who's seen 100 pitches today"
"Warm"	"Like a friend giving advice, not a teacher giving a lecture"

Comparisons work because they give the AI a complete persona and context to draw from — not just a single adjective to interpret.

2. Writing Samples (Few-Shot for Tone)

The most reliable way to match a specific tone: show the AI what it sounds like.

Rewrite this paragraph in the tone of these examples:
[Paste 2-3 paragraphs of writing in the tone you want]
Here's what I want rewritten: [your text]

This is few-shot applied to tone. The AI doesn't have to interpret "make it sound like our brand" — it sees exactly what your brand sounds like and matches it.

3. Specific Direction

When you can't provide samples, be specific about what makes the tone:

Tone: Use short sentences (max 15 words). Use contractions (don't, won't, it's). Start paragraphs with the main point, not a setup. No exclamation marks. No emojis. Address the reader as "you." Avoid corporate jargon like "leverage," "synergy," "optimize."

This is more work than "make it professional," but it produces consistent results because you're defining the specific elements that make up the tone.

Your brand voice is a writing sample, not a description
If you're trying to match a brand voice, don't describe it — show it. Paste 2-3 examples of content that hits the right tone and ask the AI to match. This is why few-shot is so powerful for tone: the AI matches a pattern, not an interpretation.
