Marketplace / garage-sale listing caption from a photo description

Selling something on Marketplace or for a garage sale and staring at a blank caption box? Describe the photo (or what’s in front of you) and let AI write the listing.

Copy/paste:

“Write a friendly Facebook Marketplace listing from this item description. Include: clear title, 2–3 short benefit bullets, condition, dimensions/size if relevant, pickup/meetup note, and a fair price suggestion range. Keep it honest — no hype. Item: [describe what you see — brand, color, age, scratches, what it includes].”

Drop that into ChatGPT, Gemini, Claude, or Grok, tweak the price to what you’d actually take, add your photo, post. Takes like two minutes instead of twenty of “how do I make this sound less sad.”

I’ve used this for furniture, kids’ stuff, random garage treasures. Honest + clear sells better than fancy anyway.
