You ask an AI to explain your new feature to customers. Seconds later you have a draft full of "innovative solutions" that could belong to any company online.
The draft is mostly correct, and the structure often holds. It just doesn't sound like you. These brand voice mistakes in AI blog posts follow predictable patterns, so you can fix them.
This guide shows you how to make an AI draft sound like your own site. You'll see seven mistakes grouped into three causes: wording, claims, and reader fit. Then you'll get a review pass you can run on any draft. One mistake costs you reader trust faster than the rest, and it isn't tone.
Key takeaway: The seven brand voice mistakes are corporate solutions language, hedging and filler, claims the site never made, implying the AI runs unattended, feature lists instead of the reader's task, wrong audience sophistication, and tone drift between sections. You fix most of them in review, against what your website already says, not by rewriting the prompt.
Why does your AI draft sound like a corporate brochure?
AI drafts default to safe, corporate phrasing because that is how most business writing reads online. That default causes mistake 1, solutions language instead of a real person, and mistake 2, hedging and filler that commit to nothing.
Brand voice is a consistent personality in wording: the same word choices, rhythm, and stance on every page. Hedging is language that softens a statement until it promises nothing, such as "may help."
Think of the AI's default voice as a hotel lobby: pleasant, clean, and built so no one feels out of place. Your site should feel like your own kitchen. A style prompt such as "be direct" helps a little, but the model fills every gap with its default.
Here's the tell: the same phrases appear in nearly every generic draft. Cut them on sight.
- Hedges: "may help," "can potentially," "it's worth noting," "arguably"
- Empty intensifiers: "truly," "incredibly," "game-changing," "cutting-edge"
- Solutions language: "innovative solution," "empowers teams," "seamless experience"
Before and after
Before: "Our innovative solution empowers teams to unlock seamless collaboration."
After: "I built this because [the problem you kept seeing]. Here is what it changes for you: [one concrete outcome]."
Your website is the style guide
To build voice rules without a formal style guide, open three pages you have already published and like, such as your homepage, about page, and a product page, then copy the five sentences that sound most like you. For each sentence, write one DO rule (for example, "Use first person when explaining why a product exists") and one DON'T rule (for example, "Don't call the product a solution"). Put those rules in your review checklist rather than only in your prompt, because short rules drawn from real pages catch drift that adjectives like "friendly" and "bold" never will.
For a full walkthrough, see how to write a blog post in your brand voice. If you would rather start from a researched article than a blank page, BloGoose gives you a draft to review against these rules.
Is the AI making claims your website never made?
Often, yes, and this is the mistake readers punish fastest. A wrong claim is a voice break, not just a factual slip, because your voice only matters if readers trust that you mean what you say.
An unsupported claim is any statement in a draft that you cannot point to on your own site. Think of a new salesperson promising a discount you never approved: the customer blames your company, not the new hire.
Spot it in under 10 seconds
| Mistake | Symptom | Fix |
|---|---|---|
| Invented statistics | A number or percentage with no source on your site | Delete it, or replace it with what your site states |
| Overpromises | "Guaranteed," "always," "in minutes" | Rewrite it to match your actual product page |
| Wrong product names | A name that differs from your pricing or product page | Copy the exact name from your site |
| Implying it runs unattended | "Automatically," "for you," "set and forget" | Name the human review step |
The honest-control rewrite
Before: "Publishes for you automatically."
After: "Drafts it, then you review the facts, the words, and what gets published."
To check an AI draft for claims your site doesn't support, highlight every number, promise, product name, and description of what the tool does on its own, then ask one question about each: can I point to this on my own site? If the answer is no, delete the claim or rewrite it to match the wording your site already uses, even when the AI's version sounds more impressive. This test works because your published pages are the record readers will compare against, so a draft that stays inside them keeps both your facts and your voice intact.
The Growth Duo follows this logic: it turns what your website already explains into Vlozy short videos and BloGoose researched articles, so your review has a source to check against. For more on this workflow, browse practical perspectives on content and growth.
Accurate claims can still miss the mark when they're aimed at the wrong reader.
How to fix a draft that talks past your reader
To fix a draft that talks past your reader, make three quick fixes. Lead with the reader's task instead of a feature list. Match their level of expertise. Then catch tone drift by reading only the H2 openers in order. The whole pass takes about 20 minutes per post.
You need: the AI draft, your brand voice notes, and a document editor with an outline view.
- Rewrite the first line around the task (5 minutes). Delete any opener that lists features. Then type one sentence that names the job your customer is trying to do. In a feature-launch post, "Our update adds scheduling, templates, and analytics" becomes "You want next week's posts ready before Friday." Move the features below that line as supporting detail. When you finish, the reader's goal should be the first thing they see.
- Calibrate the explanations (10 minutes). Your readers are comfortable with WordPress, subscriptions, and separate logins, but they are short on time. Cut any paragraph that explains those basics. Add a short plain-language clause after each unexplained acronym. When you finish, no sentence should talk down to the reader or require a glossary.
- Read only the H2 openers in sequence (5 minutes). In Google Docs, open View, then Show outline. Click each heading and read only its first sentence. You are looking for tone drift, which is when the voice shifts between sections, such as friendly in one and stiff in the next. Rewrite any opener that sounds like a different writer. When you finish, the post should read in one voice from top to bottom.
If drafting is your bottleneck, the Growth Duo delivers researched articles drafted from your site. You still review each one before it goes live.
Run the Facts, Words, Publish review before every post
Every AI blog post should pass three checks before it goes live: Facts, Words, and Publish. Each of the voice failures covered in this article, which are invented claims, brochure tone, and reader mismatch, is caught by one of these passes.
So what does that look like on a real draft? Take the founder from the opening.
- Facts: She checks every claim against her own website and deletes the promises it never made.
- Words: She compares the tone against her voice rules, replaces the brochure phrasing, and reads the H2 openers to check for drift.
- Publish: She makes a deliberate yes-or-no decision. This is a real decision, not a skim.
Should you publish AI posts without this review? No. The draft saves you writing time, and the review protects your name.
Your next step is to try the Growth Duo and run Facts, Words, Publish on every draft before it goes live. That way, the voice your customers trust stays yours.
