Brand OS Portal

AI writing that sounds like your company: what to give the AI.

AI sounds generic because it has nothing of yours. Give it your voice, your facts and a few real examples.

AI writing sounds generic when it has just your question. It fills the gap with the average of the internet. To make it sound like your company, give it four things: your voice rules, real example texts, approved facts and a never use list.

Then check every draft before it goes out. A person should always make the final call.

Why AI output looks and sounds generic.

This is a common worry among founders and marketers. The cause is simple.

Cause 1

No voice rules

The AI does not know how you sound, so it writes how everyone sounds.

Cause 2

No facts

It invents numbers and claims to fill the space.

Cause 3

No examples

It has never seen a text you are proud of.

The same thing happens with looks. Read why AI startups look the same. If you want to see what AI already says about you, run the free AI Mirror above.

The four things to give the AI.

Put them in one place, so every draft starts the same way.

Item 1

Voice rules

3 voice words, sentence length, stance, with a right and a wrong line for each.

Item 2

Real examples

3 to 5 short texts you are proud of: a post, an email, a page intro.

Item 3

Approved facts

A short list of numbers and claims the AI may use. Nothing else.

Item 4

Never use list

Words and phrases that must not appear.

Setup steps are in how to make ChatGPT use your brand voice and ChatGPT and Claude projects on brand.

Voice brief for AI drafts
You write for [company]. Our readers are [who].

WRONG: "[example line we dislike]"
EXAMPLES OF OUR WRITING: [paste 3 short texts]
FACTS you may use (nothing else): [paste the approved list]
If a number or claim is not on the list, write "not on the list" and do not invent one.

After the draft: check and edit.

A good brief gets you most of the way. The last step is yours.

  • Run the swap test. Put a competitor name in. Does the text still work?
  • Cut the big words. Replace each one with a plain word or a fact.
  • Check each number against the approved list.
  • Read it aloud. Fix any line you would not say.

Put the rules in one place, for people and AI.

The brief above works. It breaks when five people each keep their own copy.

In a Brand OS Portal, the brand rules sit in one place for your team. There is also an AI Kit with brand rules for ChatGPT and Claude, and an AI Writer. People and AI work from the same rules.

The result: your team stops waiting for a copywriter or a designer for every post. A designer or strategist is still right for a new identity. The portal is for the daily work after.

Straight answers.

Why does AI writing sound generic?

It has no voice rules, facts or examples from your company, so it writes the average voice.

How do I make ChatGPT write in my brand voice?

Give it your voice rules, real examples, approved facts and a never use list, then check each draft.

Can AI write in my company's tone?

It can come close when it has good examples and clear rules. A person should still read every text.

How do I stop AI from inventing facts?

Give it a list of approved facts and tell it to write "not on the list" for anything else.

Should I tell readers a text came from AI?

That is your call and your legal rules. Either way, a person should stand behind the text.
