A small shop owner on Etsy or eBay can save 25 hours a month and avoid paying a $20/month ChatGPT subscription by using a 3.4 GB open-source model on their laptop, instead of relying on a paid API. Listing Copilot points a Gemma 3 (4B) model at the laptop and generates ready-to-paste listings for product keywords such as "handmade ceramic mug" or "minimalist gift".
The model is run on the local machine using Ollama, ensuring there are no API calls, per-token billing, or inference leaving the device. The app generates a title under 140 characters, a benefit-driven 2-4 paragraph description, and 10-13 lowercase search tags, all without the need for any paid services. The code is simple, open-source, and can be run with Python 3.13, FastAPI, Ollama, and a single HTML file.
With this setup, the cost curve remains flat, allowing for unlimited generation of listings without any additional costs.
