This module follows the guide section by section. Keep it open as a one-page reference while you work.
Why AI content sounds the same
AI drafts are fluent and easy to forget. They reach for the same phrases every other brand uses, and readers notice. A distinct voice is what sets a brand apart, and it has to be written down to survive AI.
In the Content Marketing Institute's 2026 trends round-up, experts named a human voice, quality over volume and visibility in AI-driven search as the ways brands will stand out as AI-written content fills every channel.
Content Marketing Institute, content marketing trends for 2026| Generic AI content | On-brand content |
|---|---|
| "Write a post about X" | A brief with audience, point, facts and voice file |
| Stock phrases and hype words | Plain words from the brand's own list |
| Several points in one post | One point, stated in the first line |
| Claims without proof | Facts the brand can show |
| Published straight from the draft | Every piece approved before it goes out |
Five parts of a voice system
The answer is a system: a voice file the AI works from, a list of phrases the brand never uses, one clear point per piece, real proof and a person who approves every post.
| Part | Includes | Test it |
|---|---|---|
| Voice file | Tone, audience, words to use and a few strong samples. | Rewrite a generic draft in house style. |
| Banned list | Phrases the brand never uses, from hype words to clichés. | Search every draft for them before review. |
| One point | Each piece makes one message for one reader. | State the point in one sentence first. |
| Proof | Real facts, numbers and examples only you can supply. | Mark every claim with its source. |
| Approval | A clear path from draft to approved to published. | Name who approves each channel. |
| The editor | Knows what the brand sounds like, and what it never says. | "Would a reader know this was us without the logo?" |
Write your voice file in an afternoon
One page is enough to start. Add to it every time an editor fixes a draft.
- ReaderWho you write for, and what they care about.
- ToneThree words for the voice, each with an example.
- WordsTerms to use, and phrases the brand never uses.
- SamplesThree pieces that sound exactly right.
- RulesSpelling, punctuation and length for each channel.
The samples do most of the teaching. A tone word like "warm" means different things to different writers. Three real pieces that sound right leave far less room to guess.
Each time an editor corrects the same thing twice, add it to the file. The voice file is a record of every lesson your editors have already taught.
Five checks before anything publishes
Run them on every draft. Most take seconds.
- One point. Can you say it in one line?Try it: "What is the one thing to remember?"
- Banned words. Search for the brand's list.Try it: "Flag any phrase on the banned list."
- Proof. Every claim has a source.Try it: "List each claim and its source."
- Read it aloud. Voice is easier to hear than see.Try it: would your best writer say this?
- Sign-off. The approver checks before it goes out.Try it: name who approves this channel.
An approval path that holds at volume
Approvals by email work at five posts a month. At two or three a week they get lost. A clear set of stages lets everyone see where each piece stands.
- Draft
- Awaiting approval
- Changes required
- Approved
- Scheduled
- Published
Check these signs each month.
- Readers recognise it.
- Edits get lighter.
- No banned phrases.
- Every post approved.
Scale up when
- Drafts need light edits only. The voice file is working.
- The file answers most questions. Writers stop guessing.
- New writers match the voice fast. The samples are doing the teaching.
- Approvals run without delays. The path is clear.
Slow down when
- Drafts all sound alike. Add better samples to the voice file.
- Claims lack proof. Supply the facts first.
- Approvals get skipped. Restore the review step.
AI drafts, people decide. Publish more. Sound like yourself.
Start from the reader.
A brand voice is a promise to a reader. Every decision in the voice file starts with them: who they are, what they care about and what they need from this piece. The banned list exists because readers can tell when they are being sold to.
Starting from the reader is empathy put to work. Name their situation before your solution. Give them one clear point. Back it with something they can check. That is how a brand earns trust at volume.
- Write the Reader section of your voice file first, before tone or words.
- Open each piece with a situation your reader will recognise.
- Ask "what does the reader need from this?" before "what do we want to say?"
The content system behind 100+ posts a year
I run a company's content, brand and marketing on AI systems I designed, as a one-person content function. Every post is drafted with AI grounded in the knowledge base, then moved through a review and approval register. It replaced approvals by email.
- Volume
- 100+ original posts a year, 2 to 3 a week, on three platforms
- Voice
- A tone-of-voice standard the AI drafts from
- Check
- A review checklist for graphic, copy and first comment
- Sign-off
- Every post approved before it goes out
Draft your one-page voice file
Write a first version for your brand or team. One page is enough. You will add to it each time an editor fixes a draft.
Check your understanding.
Module 6 in four lines.
- A distinct voice has to be written down to survive AI.
- Five parts: voice file, banned list, one point, proof and approval.
- Three real samples teach the voice better than any list of adjectives.
- Clear stages from draft to published keep approvals from getting lost.
Block one afternoon this week and write the first page of your voice file.
