We built the chargeback defense tool we wished existed — fast, affordable, and powered by AI.
Every year, UK and global merchants lose billions of pounds to chargebacks — many of which are winnable. The problem isn't the disputes themselves; it's the time, expertise, and cost required to fight them properly.
ChargebackAssistant exists to level the playing field. Our AI generates professional, evidence-backed chargeback defense letters in under 60 seconds — so any business, regardless of size, can protect its revenue.
Writing a proper chargeback defense manually takes hours — time most business owners don't have.
Hiring legal help or specialist services costs hundreds per dispute — far exceeding the disputed amount.
Chargeback reason codes, evidence requirements, and deadlines vary by processor and card network.
ChargebackAssistant is powered by Anthropic Claude, one of the most capable and safety-focused AI models available. Claude analyses your dispute details, applies its knowledge of card network rules and payment processor requirements, and produces a defense letter that addresses the exact reason your chargeback was filed.
We combine AI with a structured evidence framework built around real chargeback outcomes — giving you not just a letter, but a strategy.
