Build with Swytchcode, Gurgaon, Track 6: AI Business Operator. Native iOS (SwiftUI + voice + Siri) · LangGraph agent · 5 integrations via Swytchcode: PayPal, Gmail, Notion, Jira, Slack.
Indian exporters and D2C brands sell worldwide through PayPal. When an overseas buyer files a chargeback ("never received it", "not as described", "unauthorised"), the merchant has only a few days to respond with evidence, and that evidence is scattered: tracking in the order log, the buyer's own "it arrived, love it!" email in Gmail, QC notes in Notion. Founders rarely have time to dig, so they lose disputes they should win and miss the fraud rings they should block.
Jarvis mode. "Hey Siri, brief me with Ledger." Ledger reads the founder's Notion playbook, pulls PayPal sales and open disputes plus Jira blockers, then speaks a 30-second brief: revenue vs target, money at risk, top blocker, and one recommended action.
Detective mode. "Investigate today's disputes." For each PayPal dispute, Ledger:
- pulls the dispute from PayPal
- looks up the order in Notion (tracking, ship-to address, QC notes)
- searches Gmail for the buyer's messages
- pins each decisive clue to the case board on the phone (evidence cards)
- decides based on the playbook:
| Case | Evidence Ledger finds | Verdict | Actions |
|---|---|---|---|
| John: "never received" $420 | DHL delivered and signed "J CARTER"; John's own email: "lamp arrived… looks stunning" | Contest | Submits evidence to PayPal |
| Emma: "not as described" $180 | Notion QC note: warehouse shipped teal instead of cobalt | Our fault, so settle | $72 partial-refund offer (founder approves on phone) + apology email |
| Alex: "unauthorised" $1,250 | New account, 3 orders in 40 minutes, ship-to a freight forwarder, "ship TODAY" email | Fraud | Accept claim (approval) + Jira: stop unshipped KC-1062 + Slack #ops alert |
- logs a case file in Notion and posts one summary to Slack.
Money never moves without the founder tapping Approve. This is enforced in code, not left to the prompt.
- The LLM chooses tools and their order; each result (a delivery signature, an email) changes the next step and the verdict.
- The rules live in Notion. Change the playbook (e.g. max partial refund 40% → 20%) and the same request produces a different offer.
- Rejections feed back into the loop: if the founder rejects a refund, Ledger logs the case as pending founder instead of retrying.
