Could you build this?

Partial The side panel, AI listing writer, and reply drafts are vibe-codeable. The fair-price check needs a large, current dataset of comparable Wallapop sales, which a solo builder would have to collect and maintain.

What it would actually take: The stack would be a Chrome extension with a content script, an LLM for listings and replies, and a backend for scam heuristics. The hard part is a continuously refreshed pricing model built on comparable listings, which requires scraping at scale (with the access and legal risk that entails), data cleaning, and enough volume to make price estimates credible.
