ChargeMate drafts chargeback responses for online merchants. Add a dispute or sync it from Stripe or Shopify, upload your evidence, and the AI writes a rebuttal letter matched to the Visa, Mastercard, Amex or Discover reason code, with an evidence checklist. Edit it, copy it or download a PDF. Works with any processor, and it is priced per response instead of a share of what you recover: 3 free, then packs from $5 or plans from $19/month.
