absolute lifesaver for listing junk on marketplace
two keywords and boom, clean listing description
needs you logged into chatgpt which is fine but a bit clunky
free and just drops the text right into the box
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Enter as little as two or three words about the item you are selling and receive a complete listing description written for you.
Choose normal, medium, or long output depending on how much detail your listing needs.
The generated description is transferred straight into the Facebook Marketplace description box, so there is no copy-pasting step.
The extension uses your existing ChatGPT login instead of a separate paid API, which keeps it free for you.
The developer discloses that no user data is collected, sold, or transferred for unrelated purposes.
Marketplace Buddy targets the single most tedious chore in reselling on Facebook Marketplace: writing a fresh, appealing description for every single item. The extension lives in your browser toolbar. When you open a new listing form, you click the icon, type a few words (the developer notes even two words will do), and select a length — normal, medium, or long. The extension then produces a complete description highlighting the item's key features and benefits, and writes it directly into the description box on the page.
Rather than shipping its own AI backend, Marketplace Buddy works through your existing ChatGPT login. The developer states plainly that an OpenAI account is required and that usage stays free. The extension does not collect or sell your data, per its Chrome Web Store disclosure, and the developer describes it as a solo, non-trader project.
The extension is deliberately narrow in scope and has drawn modest but positive feedback — a 3.7 average from three ratings with around 300 weekly-active users. Because output comes from a language model, the developer explicitly advises double-checking the generated text and reviewing what was transferred into the description box before posting.
You are selling a piece of furniture and want an appealing description without staring at a blank box — type the item name and generate.
Working through a garage full of goods, you generate a distinct description for each item in seconds instead of writing every one from scratch.
New sellers can use generated drafts as a template for what a clear, benefit-focused Marketplace description looks like.
