🛡️ Dispute Defender: a local AI that has to cite its evidence

说明与用途

Dispute Defender 是一款本地 AI，自动收集证据并撰写争议回复，确保每个句子都引用特定事实。它使用 Gemma 3 4B 通过 Ollama，验证每条陈述并在不添加新词的情况下修复错误。

问题

Small marketplace sellers need to respond quickly to disputes with scattered evidence and limited resources, but drafting a compliant reply that cites every fact is tedious and error‑prone.

结果

In 30 synthetic cases, 92% of first‑draft replies were clean with a single run, and 94% with three runs. The system reliably cites evidence, drops unsupported text, and repairs minor errors without adding new words.

工作流

• Provide case folder with dispute notice, order CSV, messages, photos
• Extract numbered evidence (E1, E2, …)
• Triage evidence to identify missing items
• Use Gemma 3 4B via Ollama to draft reply
• Verify each clause against cited evidence
• Retry once if needed
• Repair unsupported clauses without adding words
• Drop remaining unsupported clauses
• Output final letter, evidence list, and repairs
