ecommerceguide summary
Sell-O-Matic is a custom GPT that writes product descriptions from uploaded product images. Its prompt starters ask for target audience details, key features and a marketing angle, so the draft copy follows the answers given. Built by Ryan Yang, a verified builder, it runs inside ChatGPT with browsing, Python and image generation available, and shows a 30+ conversation count. OpenAI has scheduled custom GPTs to retire on 11 December 2026.
Why it stands out
Its four prompt starters collect audience, features and marketing angle from the seller before the description is drafted.
