Let ChatGPT Agent handle an online listing workflow
A seller used ChatGPT Agent to research, post, and monitor a sale with short check-ins over about 10 days.
- What they did
- The person started by sharing a photo of the item plus a few basic details, then turned on Agent Mode and gave it a step-by-step instruction. The agent compared similar listings, wrote the ad, and used a remote browser to publish it and draft buyer messages. It paused whenever the seller needed to sign in, verify a post or reply, or confirm the item’s details, and it later handed off shipping steps.
- How it went
- The seller said the setup reduced roughly 2–3 hours of admin to about 10–20 minutes of oversight across a 10-day selling run. It still needed human help at key points, and the agent could not fill in unknown facts, get past marketplace verification, or complete shipping; commenters also mentioned trouble with login and images.
- Tips
- This works best when you can review every listing and response yourself. It also needs a paid ChatGPT plan, starting at $20/month.
Try it yourself with ChatGPT Agent
I want to sell [item] on [marketplace]. Use the photo and details I provide to look for comparable listings, recommend a price, and draft a title, description, and image checklist. Stop before publishing and show me the full listing for approval. After it is live, watch for buyer messages, write reply drafts for me to review, and do not send anything until I approve it. Every [number] days, check the listing performance and suggest a price change if needed. If the item sells, continue only with the remaining steps I approve, and stop whenever I tell you to.
Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
