Brand OS Portal

Brand voice checker: paste text, get a score.

A voice checker reads a text and says if it sounds like your company. Here is one you can run today.

Free: your brand in 3 real designs, in 48 hours.

A brand voice checker compares a text with your voice rules and tells you what is on voice and what is not. A good one gives a score and shows the lines to fix.

You can do it by hand in five minutes with the 6 question score below. Or a Brand OS Portal can check the words against your brand voice for the whole team.

What a brand voice checker looks at.

A checker needs rules to check against. No rules, no real check.

Look 1

Words

Plain words or jargon. Words you always use. Words you never use.

Look 2

Sentences

Short or long. Active or passive. One idea or five.

Look 3

Stance

Do you sound calm, direct, warm, or loud? Does it match your 3 voice words?

Look 4

Facts

Every number and claim must be on your approved list.

No rules yet? Write them with brand voice guidelines. Short examples help most, see B2B brand voice examples.

The 6 question voice score.

Give 1 point for each yes. Five or six means ship it. Three or less means edit.

Brand voice score, by hand
Text: [paste a title or the opening line]
1. Would a customer understand every word without help?  (yes = 1)
2. Do the sentences sound like us, not like a press release?  (yes = 1)
3. Does it match our 3 voice words: [word], [word], [word]?  (yes = 1)
4. Are all numbers and claims on our approved facts list?  (yes = 1)
5. Is every word from our "never use" list gone?  (yes = 1)
6. Could a competitor NOT have written this?  (yes = 1)

Score: [ ] / 6
6-5: publish. 4: small edit. 3 or less: rewrite the weak lines, then score again.

Question 6 is the hard one. If a competitor could post the same text, the voice is too generic. More in how to check if copy sounds like your brand.

Straight answers.

What is a brand voice checker?

A tool or method that compares a text with your voice rules and shows what sounds off.

Can ChatGPT check my brand voice?

It can give a second opinion if you paste your voice rules with the text. Rules must be in the chat each time, and a person should decide.

How do I check if my writing matches my brand voice?

Compare it with your voice words, your never use list and your approved facts. The 6 question score above does this in five minutes.

What do I need before I can check voice?

Written voice rules with examples. Without them, every check is a guess.

Can a whole team use a voice checker?

Yes. Put the check inside the place where people write, so nobody has to remember the rules.

One more thing.
