About this exercise

You're presenting 3 user personas and want a portrait for each, made with Gemini. Get Claude to write exactly 3 numbered prompts, plain text, under 210 words in total. Each repeats the same style line word for word (illustrated, not photographic), says square 1:1 with head and shoulders centered, shows the persona's setting from the research summary, and says the person is fictional and not based on a real person.

Common mistakes when you ask AI for this

  • Photoreal personas. The AI asks for realistic photos, which look like real participants. Try: Add: "Illustration, not a photo."
  • Different styles. The AI rewords the style, so the 3 slides don't match. Try: Add: "Repeat the same style line word for word."
  • Losing the research details. The AI makes generic portraits or adds the merged persona. Try: Add each persona's setting from the summary.
  • Not marking them fictional. Nothing stops the tool from echoing a real face. Try: Add: "Fictional person, not based on a real person."
  • Headings and notes. The AI bolds persona names and adds tips. Try: Add: "Exactly 3 numbered prompts, plain text."

What a strong prompt includes

  • Asks for 3 prompts
  • Repeats the style
  • Asks for illustration
  • Marks them fictional
  • Sets the framing
