Before You Use Any AI Writing Tool Make a Voice Sheet (Here’s How)
AI writing tools are only as good as the instructions you give them. Build a one-page Voice Sheet first, and your blog posts will sound like you, not like everyone else
Before You Use Any AI Writing Tool Make a Voice Sheet (Here’s How)
Two bloggers can open the same AI tool, type almost the same request, and publish two very different posts. One sounds like a person with opinions. The other sounds like a brochure.
The difference usually isn’t the tool. It’s whether the writer told the tool who they are, who they write for, and how they sound.
This guide shows you how to build a one-page Voice Sheet that you can reuse with any AI writing tool, from general assistants like ChatGPT, Claude, and Gemini to grammar tools like Grammarly.
Free plans and pricing for these tools change often, so check each official site before paying.
Why Generic Prompts Give Generic Posts
An AI tool predicts what a typical answer looks like. Ask for “a blog post about password managers” and you get the typical version: an intro, a list, a conclusion.
That’s fine for a first draft of structure. It’s a problem if you publish it, because readers and ad reviewers can spot posts that say nothing new.
A Voice Sheet pushes the tool away from “typical” and toward “you.
Build Your Voice Sheet in 30 Minutes
Open a notes file and answer seven short prompts. Keep each answer to a few lines.
1. Who am I writing for?
Be specific. “Beginners” is vague. “People over 30 switching careers into web design, without a technical background” is useful.
2. What do they want?
What problem is the reader trying to solve when they land on your post? Write it as a sentence.
3. What do I know that most writers on this topic don’t?
This is your edge. Examples: “I’ve run a small shop for six years,” “I learned coding at night while working a day job,” “I’ve tested these tools on real client projects.”
4. How do I sound?
Pick three or four words, such as plain, friendly, a little humorous, direct. Then add what you avoid: “no corporate phrases, no hype.”
5. Words and phrases I use, and ones I don’t
Write down three phrases you’d actually say and three you wouldn’t. This helps the tool avoid stiff, robotic wording.
6. A sample paragraph of my real writing
Paste 100 to 150 words you wrote yourself. An email, a social post, or an old blog paragraph works. This single step does more than most prompt tricks.
7. My firm opinions
List two or three things you believe about your topic. For example: “You don’t need paid tools in your first six months.
How to Use the Voice Sheet
Paste the sheet at the start of a chat with your AI assistant, then add your task. Here are three ways to use it.
For ideas:
“Using my Voice Sheet, suggest 15 post ideas that match my reader’s problems and my experience.”
For an outline:
“Draft an outline for [topic]. Include a section where I share my own experience. Leave a note where I should add a real example.”
For editing your draft:
“Here’s my draft. Edit it for clarity while keeping my voice from the Voice Sheet. Don’t add facts. Mark anything unclear.”
Notice what’s not there: “Write the whole article.” You’ll get better results, and a more original post, if you write the core yourself.
The Generic Test
Before publishing any post, run this quick check. It takes five minutes.
- Swap test: Replace your blog name with a competitor’s. Does the post still make sense? If yes, it’s too generic.
- Proof test: Is there at least one detail only you could provide, such as a screenshot, a number, or a mistake?
- Opinion test: Does the post take a position anywhere, or does it only list options?
- Read-aloud test: Does it sound like something you’d say to a friend?
- Fact test: Did you verify every name, date, and number?
If a post fails two or more, rewrite the weak sections before publishing.
Which Tool for Which Job
You don’t need many tools. Match the type to the job.
| JobTool typeExamples | ||
| Brainstorming and outlining | General AI assistant | ChatGPT, Claude, Gemini |
| Research with sources to check | Research-style assistant | Perplexity |
| Final grammar and tone check | Grammar and style tool | Grammarly, ProWritingAid, Hemingway |
| Search-focused content gaps | Content optimizer, later | Surfer, Frase |
Dedicated platforms like Jasper, Writesonic, and Copy.ai are mainly aimed at marketing teams producing a lot of content. Most small blogs get along fine with a general assistant and a grammar checker. Compare current plans before you subscribe.
A Short Example
I gave the same prompt to an AI tool twice. The first time, I used no Voice Sheet, and the opening sentence was generic: “Your email account holds the keys to your digital life, so knowing whether it has been compromised is essential.” The second time, I pasted my Voice Sheet first, and the opening sounded closer to how I talk: “Is your email hacked? Here is a quick way to check.” The second draft was shorter, used simpler sentences, and avoided the formal tone of the first. My Voice Sheet is short: it lists my sentence length, three words I use, two words I avoid, and my tone.
Mistakes to Avoid
- Skipping the Voice Sheet and using a different style in every post
- Letting the AI write the entire post, then only fixing typos
- Trusting facts, prices, or statistics without checking
- Copying prompts from others without adapting them to your reader
- Publishing without a single personal detail
Update the Sheet Every Few Months
Your voice and your readers will change. After 10 posts, reread the sheet. Add new opinions, new phrases, and anything readers have said in comments. Treat it as a living document.
Final Thoughts
The best AI tool for writing blog posts is the one you can steer. A Voice Sheet gives you that steering wheel, and it works with whichever tool you choose.
Spend 30 minutes making yours this week. Then write your next post with the sheet open, and see how different it feels from a one-line prompt.
