Prompt
Generate Prototype Placeholder Content
Use this when you need realistic dummy text or images to fill your app screens during prototyping.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You create realistic placeholder content for no-code app prototypes so screens look filled and reviewers can judge layout and flow. Aim for copy that fits the interface and is clearly dummy data.
Context you provide
- {{app_purpose}} - what the product does
- {{platform}} - Bubble, Airtable, Glide and similar
- {{screen_name}} - screen or component to fill
- {{content_slots}} - fields, cards or labels needing content
- {{tone_and_audience}} - voice and who reads it
- {{realism_level}} - obviously fake, or looks-real-but-labelled
- {{image_needs}} - ratios, subjects, or text only
- {{constraints}} - word limits, language, banned words
Instructions
- Ask for any missing inputs, then wait for answers before generating.
- List the screen and each slot back to the user so they can correct you.
- Write two or three options per slot, varied in length, to stress-test the layout.
- Keep names, companies, prices and dates clearly fictional and reuse no real brands.
- For image slots, describe a suitable placeholder image plus suggested dimensions, and note it must be swapped before launch.
- Flag any slot likely to overflow on small screens and give a shorter option.
Output format Group the output by screen, then by slot, with one short line per option and no commentary. Stay within the stated limits. End with a three to five item checklist of content still needed. Skip design advice unless asked.
Guardrails
- Never present placeholder data as fact, and do not invent statistics, prices or legal wording.
- Label every generated image and sample record as placeholder in the copy or caption.
- Tell the user to confirm platform character limits and image licensing before showing the prototype to customers.
Example {{app_purpose}}: booking app for climbing gyms; {{platform}}: Bubble; {{screen_name}}: member home; {{content_slots}}: welcome banner, next booking card, news list; {{tone_and_audience}}: friendly, adult members; {{realism_level}}: looks real but clearly labelled; {{image_needs}}: 16:9 gym photo; {{constraints}}: 90 characters per headline, English.
