KathaYantra: The Ghost Is the Story — An Open-Weight Folklore Atlas

说明与用途

KathaYantra 是一个数字化民俗档案和交互式地图，利用开放权重 AI 生成基于已验证记录的答案，并将真实故事与 AI 生成的虚构内容区分开来。

问题

Folklore and urban legends are scattered across oral traditions, archives, and online sources, making it hard to trace their origins, verify cultural context, and avoid model hallucinations.

结果

KathaYantra provides a traceable, source-aware folklore archive that mitigates hallucinations by grounding AI responses in retrieved records, while preserving cultural context and distinguishing authentic narratives from AI-generated fiction.

工作流

• Explore the atlas via the global map
• Enter a country collection and browse folklore and urban legend records
• Open a record to inspect metadata and follow source references
• Ask the Archivist a question to retrieve relevant records and generate a grounded answer
• Compare narratives across records
• Keep AI-generated fiction separate from authentic archive seed records
