Can ChatGPT write our brand voice guide?

It can draft section headers. It cannot know how your founder talks on sales calls or which phrases legal already approved. Paste real headlines, emails, and ads first; do not invent sample copy.

What belongs in a brand voice guide?

Do/don't example pairs from your site, a banned-word list, audience sentence, channel notes (email vs social), and who approves exceptions–not ten pages of "warm but professional."

Should I humanize the whole guide?

Humanize explanatory prose between examples. Leave quoted copy, legal claims, and trademark lines exact.

Is this the same as product marketing copy?

Related artifact. Product posts lock claims on one page. Voice guides govern all pages. Build the guide first; landing pages inherit.

Humanize Brand Voice Guide With Examples

Brand voice guides fail when they describe a personality nobody recognizes on the homepage. ChatGPT produces "approachable yet authoritative" with no sentence from your product. New writers ask: what would we actually say in the hero?

Human Writes is the clarity pass after real do/don't examples, banned words, and audience are pasted in. It does not invent tone from adjectives.

What teams punish

Problem	Symptom	Fix
Adjective stack	"Bold, human, innovative"	Replace with do/don't pairs
No real examples	Guide cites generic SaaS	Pull from shipped URLs
One voice for all channels	LinkedIn sounds like error messages	Channel table
Banned list missing	"Leverage" returns every quarter	Words you never say
No approver	Freelancers guess	Named owner + Slack channel

CMOs compare the guide to live copy and sales decks. If the hero violates page one of the PDF, the doc is shelfware.

Lock examples before ChatGPT

Build an example bank from copy that already shipped (with permission):

Type	Do (paste real line)	Don't (rewrite or reject)
Hero headline	"Paste stiff AI drafts. Keep your facts."	"Unlock seamless content excellence"
Error message	"That file is too large. Max 10 MB."	"We encountered an issue processing your request"
Email subject	"Your quota resets Monday"	"Exciting updates await inside"
CTA button	"Humanize draft"	"Get started today" (alone)
Support macro	"Refund issued–see Stripe receipt."	"We apologize for any inconvenience"

If the Do column has fewer than five rows, stop. Record a founder sales call or export top-performing emails before drafting the guide.

Prompt with the table and: "Brand voice guide sections: Audience, Principles (3 max), Do/Don't table, Banned words, Channel notes. Do not invent new example sentences–use the table verbatim."

Guide skeleton that ships

One-sentence audience – role + situation, not demographics mush
Three principles max – each tied to an example ID from the bank
Do / Don't table – minimum ten pairs from real copy
Banned words – include model favorites ("leverage," "robust," "seamless")
Channel notes – email (full sentences) vs ads (character caps) vs social (link to Twitter thread post)
Approver – who signs off when copy breaks a rule for a good reason

Section	Humanize?	Why
Quoted Do examples	No	Sacred text
Principle explanations	One pass	AI loves hedging
Banned list	No	Exact strings
Channel notes	Light pass	Keep limits numeric
Legal footnote	No	Counsel owns

Before and after (principle paragraph)

AI brand voice draft:

Our voice is authentic, innovative, and customer-centric. We strive to communicate with clarity while maintaining a warm and professional tone that resonates across all touchpoints and empowers users to achieve their goals.

After example bank + one humanize pass:

Audience: Solo founders and agency leads pasting AI drafts they still have to ship. Principle–specific over superlative: Say what the tool does in one verb. Do: "Humanize draft." Don't: "Revolutionize your content workflow." Banned on first mention: seamless, leverage, cutting-edge. Ads: Headlines ≤30 characters; claims on approved sheet.

Second version gives writers pasteable rules, not mood board adjectives.

Onboarding writers and freelancers

A guide nobody opens is not a guide. Ship it with:

Step	Owner	Deliverable
Week 1	Marketing lead	30-min walkthrough of Do/Don't table
First draft review	Approver named in doc	Comment in Notion, not Slack DM
Freelancer kit	Ops	Guide link + two approved URLs + banned list paste
Quarterly refresh	Same owner	Re-export hero and one email; diff against PDF

When a freelancer breaks voice for a good reason (legal asked for a hedge), capture the exception in the guide's changelog. Future writers learn from approved deviations, not from guessing why one landing page sounds different.

Workflow

Export hero, pricing caveats, three emails, two ads, one error string from production.
Mark Do vs Don't with marketing + one sales rep in the room.
List banned words from last quarter's "why does this sound like ChatGPT?" thread.
Draft guide structure from the bank–not "write our brand voice guide."
One Human Writes pass on principle and channel prose only.
Link to live URLs for each Do example; date the export in the footer.
Onboard freelancers with the guide + one case study they must read.

Landing page execution: product marketing copy. Comparison pages with honest tables: comparison landing.

What not to do

Quote competitor copy as your "Don't" without labeling it external.
Humanize until Do examples change meaning or claims.
Publish ten principles–writers remember three.
Skip channel section because "voice is voice."
Let the guide live in PDF only; paste the Do/Don't table into Notion where writers work.

Bottom line

Brand voice guides win on real do/don't pairs from shipped copy, not trait lists. Human Writes is the prose pass after your example bank is true.

Paste principle paragraphs on Human Writes when every Do line still matches something live on your site.
