What makes the drafts good

It writes like someone who's read the rulebook.

Most "AI chargeback letters" are generic. Ours are keyed to the exact reason code — citing the network's own evidence requirements so the issuing bank's representment team has nothing to bounce back.

Reason-code aware

18 codes covered across Visa (10.4, 13.x), Mastercard (4837, 4853, 4855, 4863), Amex (F24, F29), and Stripe-generic. Each one has its own evidence schema.

Pulls your evidence

When the Shopify app launches, it auto-pulls tracking, AVS/CVV, login history, and fulfillment data straight from your store. No copy-paste.

60-second turnaround

From dispute open to a polished draft in under a minute. Most reason codes give you 7–20 days — don't waste them on the first paragraph.

Coverage

Every reason code that actually loses merchants money.

We picked the codes responsible for ~85% of dispute volume on Shopify Payments + Stripe — the ones with documented evidence requirements that most merchants get wrong.

    Claude reads the notice and the network-specific evidence rules, then writes a structured rebuttal — every required section in order.

  3. 03

    Submit
