Teach an AI Your Brand Voice
A 15-minute setup so everything you generate sounds like you, not a generic robot.
Generic AI output sounds generic because you never told it who you are. Fifteen minutes of setup fixes that for good.
Gather three real samples
Pick three pieces of writing that already sound like you — an email, a caption, a page from your website. Actual samples work far better than describing your voice in adjectives.
Describe the voice in your own words
Add a short brief alongside the samples: who you're writing for, what tone to avoid ("never salesy," "no exclamation points"), and a sentence or two you'd never say. Contrast helps more than praise — telling it what you're not is often more useful than what you are.
Save it as a standing instruction
In ChatGPT, this goes in Custom Instructions or a Project. In Claude, it's a Project's custom instructions. In Gemini, it's your saved personal context. Paste your samples and brief once, and every new chat in that space starts already sounding like you.
Test it on something low-stakes
Ask for a short caption or a two-line email reply first. Compare it to how you'd actually write it, and tell the AI exactly what felt off: "too formal," "too many adjectives," "I'd never start a sentence like that." This feedback loop matters more than the initial setup.
Refresh it occasionally
As your voice evolves — or if you notice it drifting back to generic — swap in a newer sample. A five-minute refresh every few months keeps everything you generate sounding like you, not last year's you.
Frequently asked questions
How do I teach an AI my brand voice?
Give it three real samples of your writing plus a short brief on your tone and what to avoid, then save it as a standing instruction (Custom Instructions or a Project). Every new chat then sounds like you.
Why does AI writing sound so generic?
Because it has no context about you. Generic input gets generic output — feed it real samples of your voice and a clear brief, and the results start sounding like you instead of a robot.
How long does it take to set up an AI brand voice?
About 15 minutes: gather three samples, write a short brief, and save it once. A five-minute refresh every few months keeps it current as your voice evolves.
