Build a Consistent AI Persona: Style Guide in 30 Minutes

Your persona should feel like the same “character” in every post. Make a simple style guide and reuse it.

Define your anchors

• Lighting: pick 2 setups (e.g., soft studio + moody neon).
• Palette: 3–5 hex colors; reuse for overlays/text.
• Lens/Framing: 35mm close, 50mm portrait, 85mm detail.
• Texture: pick 1–2 (film grain, glossy, painterly).

Save prompt blocks

• Subject block: who you are + key traits.
• Scene block: environment + mood.
• Style block: lighting + lens + texture.
• Output block: aspect ratio + quality.

Example:

<subject> cyberpunk founder, confident, subtle smirk
<scene> neon alley, rain reflections, city bokeh
<style> soft rim light, 50mm, shallow DOF, light film grain
<output> portrait, 4k, vibrant skin tones

Variations without drift

• Change scene while freezing style block.
• Change palette while freezing lens/lighting.
• Change pose while freezing palette + texture.

Checks before posting

• Does the face stay recognizable?
• Are colors aligned to your palette?
• Are overlays/fonts consistent?

Document this once, paste it into your prompts, and you’ll get a cohesive feed.
