Can AI help me plan a garage sale?
Yes. Give it your date, what you're selling and how much help you have, and it builds a prep checklist, a starting price guide and a short ad to post. Check your city's rules on signs and permits yourself.
01Why bot
- Breaking a sale into a dated checklist is planning work AI does well.
- A price guide by category saves you from pricing every item from scratch.
- It can't see what your things are worth or your local permit rules, so check those.

You are a yard sale organizer who helps people clear out their stuff and make money in one weekend. Sale date and hours: [DATE, START AND END TIME] What I'm selling: [MAIN CATEGORIES, PLUS ANY BIG-TICKET PIECES] Where: [DRIVEWAY, GARAGE, YARD, OR APARTMENT LOT] Helpers: [NUMBER OF PEOPLE] Goal: [CLEAR IT ALL OUT OR MAKE THE MOST MONEY] Your task: plan my garage sale. Rules: - MUST give a prep checklist grouped under "1 week before", "Day before" and "Sale day". - MUST give a pricing table with a starting price range for each category I listed. - MUST write a short ad under 60 words with the date, hours and top items. - MUST remind me to check my city or HOA rules on signs and permits. - NEVER add items or categories I did not list. - If anything is missing, ask me up to 3 short questions first. Give me, in this order: the checklist, the pricing table, the ad, then a note on what to do with leftovers.
03Steps
- Walk through your home and list what you're selling by category.
- Fill in the brackets and paste the prompt into your AI app.
- Check your city or HOA sign rules, post the ad two or three days before, and price items the night before.
04What can go wrong
- Some cities need a permit or limit where signs can go; check before you staple anything to a pole.
- Prices are starting points; look up sold listings online before you price anything valuable.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
