ClawBack is an AI-powered platform built to help exporters understand and recover tariff costs they may have absorbed. It uses Gemma 4 to extract important information from invoices, price-revision emails, bank receipts, and other documents, turning scattered business records into structured evidence.

The extracted information is then verified and processed through a deterministic calculation engine, rather than relying on an LLM for financial calculations. ClawBack calculates the potential amount recoverable and organizes the evidence into an absorption ledger and claim/negotiation package, making it easier for exporters to understand what they are owed and negotiate with buyers.
