TL;DR
What did @JaneOnAI use ChatGPT for?
Wanting to sell things faster on Facebook Marketplace, someone asked ChatGPT to write the description and tags for each listing and suggest an asking price; they listed 4 items that day and say 3 sold. They say 3 of the 4 items had already sold the same day, and that you don't need to be a tech person to do it.
What they did
Instead of writing Marketplace posts by hand, they asked ChatGPT to write each listing for them: the description, the tags and a suggested price. They did this for 4 items in one day.
How it went
They say 3 of the 4 items had already sold the same day, and that you don't need to be a tech person to do it.
Worth knowing
- Check the suggested price against similar local listings, since ChatGPT can't see your area's market unless it searches. Make sure the description matches the item's real condition and any flaws.
- Price check: ChatGPT: free plan; Go: US$8/month (checked Nov 1, 2026).

Try it yourself
Paste this into a chatbot, then add your own details underneath.
I'm selling this on Facebook Marketplace: [item, brand, model, age, condition, any flaws, what's included]. Write a short, friendly listing with a clear title, a description that mentions the condition honestly, and 5 search tags. Then suggest a fair asking price range and explain how you got it.
