leboncoin uses generative AI to help users write better classifieds ads, driving a 20% increase in inquiries and transactions
Many leboncoin users suffer from 'blank page syndrome' when writing ad descriptions, and those discouraged by the process post minimal descriptions, creating a vicious cycle of poorly described items that don't sell well and reduce seller engagement on the platform.
Early AI-generated descriptions were too verbose and formal, reading more like product catalogs than authentic leboncoin ads, and failed to match the platform's natural, concise conversational tone.
Ads using the AI description feature see a 20% increase in both inquiries and completed transactions, and the feature earned leboncoin the Grand Prix Favor'i e-commerce grand prize for innovation in March 2025.
