Teach AI Your
Brand Voice in 7 Steps
ChatGPT sounds generic because it doesn't know your brand. AI tools that apply these 7 steps capture your real voice. Practical method for Postuby, Jasper, Brand Voice.
⚡ TL;DR
Telling AI "write friendly" isn't enough. Give it examples, a vocabulary list, phrases to avoid, and a feedback loop. AI imitates; you correct; it learns.
Pick 3 Character Adjectives
Polite or direct? Witty or earnest? Professional or rebellious? Instead of a paragraph, 3 sharp words: "warm, direct, lightly witty." AI uses these as anchors.
Collect 10-15 Sample Posts
Pull your best 10-15 posts. AI learns from these. Quantity matters — 3-5 is too few, 50+ adds noise. Sweet spot: 10-15.
Write Down Words You Don't Use
List AI's clichés: "amazing offer," "don't miss out!," "incredible," "stunning." Your brand doesn't use these? Make a negative list. "Never use these words."
Define Sentence Length
Short and punchy? Long and explanatory? Mixed? Average post length? Emojis? Hashtag count? These details lift AI's tone-match rate from ~40% to ~85%.
Write the Audience Persona
Who are you writing to? Age, interests, pain points, language level. AI writing to a consumer uses casual; writing to a CFO is drier. Persona = half the tone signal.
Build a Feedback Loop
AI wrote, you edited. Give the edits back to the AI: "you wrote X, I changed to Y." Tools like Postuby remember these. ChatGPT doesn't — fresh start every time.
Add a Visual Style Guide
Visual tone matters too. Brand colors, font, photo style (bright/dark, minimal/full, natural/studio). Postuby has a Brand Dictionary; Canva has Brand Kit.
