Almost every creator I work with can describe their brand voice in vague positive adjectives — "approachable, smart, a bit funny" — and then can't tell you what specifically makes a sentence sound like them. That gap is why AI tools, ghostwriters, and new team members all produce content that feels off-brand: nobody knows what "on-brand" actually is.
This worksheet fixes it. It takes about 30 minutes. The output is a one-page brand voice document you can hand to anyone — including AI — and get back content that actually sounds like you.
Why "professional but friendly" isn't a brand voice
Adjective lists describe how you want to sound, not how you actually sound. They're a goal, not a fingerprint. A real brand voice is the specific set of choices that show up consistently across everything you write: sentence length, word preferences, what you'll never say, what you reach for under stress.
When AI repurposing tools fail to capture your voice, it's almost always because you described it with adjectives instead of examples. The fix is going one layer deeper.
The worksheet (30 minutes)
Part 1: The 5-piece reference set (10 min)
Pull together five pieces of your own writing you'd be proud to publish again. Tweets, LinkedIn posts, newsletter sections, blog paragraphs — whatever format you live in. They should be the ones that felt unmistakably like you when you wrote them.
These five pieces are the only source of truth for your voice. Everything else is interpretation.
Part 2: Word and phrase audit (10 min)
Read your five pieces and fill in these two lists:
- Words/phrases you reach for repeatedly. Look for the unusual ones. "Ship" instead of "launch." "Stack" instead of "tech stack." Ampersands instead of "and." The verbs you default to under pressure.
- Words/phrases you'd never say. "Synergy." "Leverage." "In today's fast-paced world." Make this list long. AI tools and contractors lean heavily on these by default; an explicit avoid-list dramatically improves output.
Part 3: The three structural rules (10 min)
Write three sentences that describe how your writing is structured. Examples from real creators I've worked with:
- "I open with a contrarian one-liner, never a setup. The first sentence has to argue."
- "Every paragraph ends on a specific number or proper noun. No vague claims at the end."
- "I use em-dashes — but never semicolons. Semicolons sound corporate."
These three rules are what's hardest to articulate and what matters most. They're also the most useful instructions to give an AI tool or ghostwriter.
Put the worksheet output (reference samples + reach-for list + avoid list + 3 rules) on a single page. Title it 'My Brand Voice — v1'.
How to actually use this output
Three concrete use cases, in order of impact:
1. AI repurposing tools
Drop the worksheet (or just the reference samples) into ClipForge's brand voice training, or paste it as instructions into ChatGPT/Claude. The reference samples + the avoid list combined produce noticeably more on-brand output than either alone.
2. Ghostwriters and contractors
Ghostwriters who get this document on day 1 onboard 3× faster. The five reference pieces tell them what excellent looks like; the avoid list tells them what gets rejected.
3. Your own writing
When you're stuck or rushed, the three structural rules are an emergency checklist. Reread them before you publish and you'll catch the off-brand sentences before your audience does.
Skip the manual setup
ClipForge's brand voice training does this in 60 seconds — drop in your samples, and every clip generated after sounds like you.
Train your voiceRevisit it every 6 months
Your voice is allowed to evolve. The mistake is letting it drift by accident. Twice a year, redo the worksheet with five fresh reference pieces. Version it (v1, v2…). Look at the diff. If your phrase audit has changed dramatically, decide deliberately whether to embrace the new voice or course-correct back.
Creators with the most recognizable voices are usually the ones who treat voice as a managed asset, not an inherent personality trait. It's a craft. Keep an eye on it.
