Justt is an AI-native chargeback management platform designed for merchants handling high dispute volumes. Unlike template-based tools, Justt generates dynamic, case-specific evidence for every chargeback. Each dispute is automatically built using the most relevant data points — selected from 500+ signals across PSPs, third-party data sources, and merchant inputs. The platform is fully automated and scales without quality loss, even during volume spikes. Using continuous optimization, including issuer-level learning and A/B testing, Justt improves performance over time while adapting to changing card-scheme rules. Merchants use Justt to recover more revenue, reduce manual work, and make ROI-driven decisions on which chargebacks to fight — with minimal integration effort.
