How GoMimic Learns a Client's Voice
A new writer joins an account and asks how the client sounds. Someone says "sort of warm, but not too warm," and sends a PDF from 2022. We've all been there.
GoMimic keeps the answer on the client instead, where your whole team can read it.
What You Keep for Each Client
Every client has a page holding how they sound, so a new writer doesn't have to ask. We've written more on what a client's voice holds and what a new piece is written with. It has four parts, and knowing which is which tells you where to look when something sounds off.
What We've Learned is what their own writing shows: how they open a post, how they close, phrases they return to, and the small things a client notices at once, like US or UK spelling. Each habit names the posts it came from.
Your rules are what your team knows that their blog doesn't: how they sound, words to use and avoid, and plain choices like contractions and sentence length. Where your rule and their writing disagree, your rule wins.
Business Facts holds what they sell, who they sell to, and what you're allowed to say about them.
Sounds Like Us holds real examples, because "long, layered sentences" describes a rhythm and a long, layered sentence shows it. Doesn't Sound Like Us holds the opposite.
Why One Unusual Post Can't Bend Their Voice
One post could be a fluke. When the same habit keeps turning up, it's confirmed and listed under What We've Learned, with the posts it was seen in, so anyone on your team can go and check.
So give it several different pieces. One post that ran on three sites is still one piece of writing.
Give It Their Writing, Not Yours
The test is simple: did the client write this? Writing samples you add count, and so do posts read from a link, posts from their blog feed, and pasted text you ticked as theirs.
Their website is treated differently: it gives you suggested rules you can Add or Skip, and nothing from it is a rule until you save it.
In our view, three choices make the biggest difference:
- Pick pieces the client would call theirs. A post your last writer ghosted teaches that writer's habits. If the client loved that voice, fine. If not, leave it out.
- Keep one voice to one kind of writer. If the company page says "we" and the founder says "I," give them separate voices. A post teaches only the voice it was made in, and mixing them blurs both.
- Skip the boilerplate. Legal pages and press releases are real writing, and they rarely sound like anybody.
Put Anything Risky in Things Never to Say
If a client would be upset by a slip, put it in Things Never to Say. Put a phrase in quotes and new pieces leave it out, and the sentences around it stay as they were. Each voice's Avoid list works the same way, and your agency's Stock Phrases stay out too.
Everything else you've written down shapes the piece too, so read for it before you sign off.
Approved Work Waits for You
A post your client approved tells you something, but a yes doesn't mean they loved every line. So what an approved post shows is listed under Learned From Approved Work, apart from the habits their own writing taught. New writing uses one only after you press Keep.
Client comments work the same way. "We say clients, not customers" stays a comment until you press Keep This for Next Time. Then it becomes a rule for that voice, and the rule remembers who said it, on which post, and when. You won't have to fix that word a sixth time.
We built it this way on purpose. Our founder led a content team's move from freelance writing to AI-assisted writing in early 2025, and kept editorial review through it. We hold to the same belief here: software can check the routine items, and a person judges tone, topic coverage, flow, and intent.
When a Client Starts Writing Differently
Clients change. A new marketing lead arrives, the founder finds a new way of putting things, or the whole brand moves. You don't have to rebuild anything, and three things stay yours to do.
Keep a habit you never want to lose, and it stays. Remove one that's wrong, and it's never learned again, even if it turns up in their next ten posts. After a rebrand, press Start Voice Over. It clears what was learned, and your rules and kept habits stay unless you tick the box. Then add a few pieces in the new voice.
What Your Team Still Reads For
- Thin sources stay thin. A voice shapes how something is said. It can't add a point of view the source doesn't hold.
- A new client starts plain. With nothing to read, posts use a plain, neutral voice. That's a little dull, and it's the honest result of having nothing to go on.
- The Mimic Voice Score isn't a grade. It says how much of a voice can be seen in what you gave us. It doesn't say how good a piece is.
- A person still reads everything. That's why your team signs off before anything reaches the client.
Twenty Minutes With a New Client
None of this is required, and Create works from day one. If you have twenty minutes for a new client, this is the order we'd spend them in. A new voice also shows What Would Help Most, which points at the same things.
- Add several pieces of their writing. Different pieces, by the person you're writing as. Have a custom GPT or a style guide? Bring it in, and tick what to keep.
- Say how they sound, in a sentence or two. Write it for a new hire.
- Fill Things Never to Say and Facts We Can Use. Real figures only come from Facts We Can Use, so this is what keeps a draft from inventing a number.
- Read a sample with Test This Voice. Change a rule and test again. Nothing is saved, and a sample never teaches the voice.
- Read What We've Learned. Remove anything that's wrong, and keep what you never want to lose.

Fixing a Piece That Sounds Off
Start with the symptom, and fix it where it lives. A fix in the right place lasts, and a fix in the piece only lasts for that piece.
| What you see | Where to fix it |
|---|---|
| A banned phrase got through | Check it's in quotes in Things Never to Say, or on Avoid |
| Wrong spelling or punctuation | Add more of their writing, or say it under More Rules |
| Too many contractions, or too few | Make the choice in the voice's rules |
| The same comment, month after month | Keep This for Next Time on the client's comment |
| A made-up figure | Add the real ones to Facts We Can Use, and read for it before sign-off |
| It sounds like the founder, not the company | Add a second voice, and move the post to it |
| It sounds like everyone | See what's on What We've Learned. A short list means it needs more of their writing |
| A habit that's plain wrong | Remove it from What We've Learned |
| After a rebrand, it sounds like the old brand | Start Voice Over, then add new pieces |
Questions People Ask
How does GoMimic learn a client's voice?+
It reads the client's own writing and notes the habits that keep turning up, confirming one when it keeps turning up. Your agency's rules sit beside those habits, and win where they disagree.
How much writing does GoMimic need from a client?+
A habit has to keep turning up before it counts, so a few different pieces is where the list starts to fill, and more gives it more to confirm. You don't need any to begin: with nothing to read, posts use a plain, neutral voice.
Can I see what it has learned about a client?+
Yes. Confirmed habits are listed under What We've Learned, with the posts each was seen in. Remove one and it's never learned again.
Does what a client approves change the voice?+
Only if you say so. Habits from approved work are listed apart, and new writing uses one only after you press Keep. A client's comment becomes a rule only when you press Keep This for Next Time.
What happens to the voice after a client rebrands?+
Press Start Voice Over and add a few pieces in the new voice. It clears what was learned, and your rules and kept habits stay unless you tick the box.
Does one client's voice reach another client?+
No. The habits and facts are saved on that one client, in your account, and they aren't shared with another client or another agency.
Does the voice get better the longer we use it?+
We don't score that. What grows is what it has to work with, as you add their writing and your rules. You can read a sample at any time with Test This Voice and judge for yourself.
