RMB 8,000 per case: AI extracts litigation discovery document key points to generate case summaries (Monthly revenue 30k+)
Workflow: Lawyers upload all electronic documents from the litigation discovery stage (scans, chat logs, transfer vouchers, etc.)
Key Fields
FIELD STAMPS🔧 Workflow
Lawyers upload all electronic documents from the litigation discovery stage (scans, chat logs, transfer vouchers, etc.) to the agent's exclusive workstation. The agent automatically completes OCR text recognition, evidence chain correlation matching, legal entity identity verification, dispute focus extraction, and timeline generation daily, outputting structured summary reports that can be directly used for case filing or defense. Lawyers only need 10 minutes to review core points, and after confirming they are correct, can export and deliver. The single-case delivery cycle does not exceed 24 hours. Upon completion, case file data is automatically archived and unnecessary cache is cleared.
🛠 Setup Requirements
Requires applying for Large Language Model API permissions supporting a 128k token long context, paired with a vector database to store case knowledge bases for different causes of action. Use no-code/low-code platforms like Dify to build the full workflow of document parsing, evidence correlation, and summary generation. No complex coding skills are required, and the overall development and setup cycle is 3-4 weeks. In the initial stage, trial permissions can be obtained through legal tech communities and local law firm intern lawyer channels to verify the compliance and accuracy of the delivery process before scaled promotion.
