What they did
After rolling Gemini out company-wide, with a partner setting up the first connectors, Dojo used the Gemini platform for more complex agents that handle unstructured data. The Chargeback Agent analyzes the emails in a dispute together with the matching transaction records, builds a structured response, and generates the report card networks expect. A separate agent classifies and extracts data from onboarding and compliance documents.
What happened
The company says the Chargeback Agent cut processing time for complex dispute cases by 70%, and the document agent brought onboarding from hours to minutes.
Keep in mind
This is a vendor case study with no accuracy or win-rate figures for disputes. It does not describe how staff review the agent's responses before they go to card networks.
Try it with your agent
Here is a chargeback case: the customer and bank emails in <dispute email file> and our records in <transaction export>. Summarize the reason code and the customer's claim, list the evidence we have that supports or weakens our position, and draft a response in <the card network or acquirer template>. Flag any missing evidence, and do not send anything.
Replace the <angle brackets> with your own details.
