🔧 Workflow

Lawyers first organize contract templates, judicial interpretations, and typical case libraries for vertical industries, import them into a RAG vector database, and configure review rules. After clients upload contracts pending review, the AI automatically compares risks, marks missing items, and outputs modification suggestions. Lawyers only need to review high-risk clauses to provide the final legal opinion. Daily operations include spending 1 hour updating the knowledge base and 1 hour reviewing AI outputs, with the remaining time dedicated to expanding B2B subscription clients.

🛠 Setup Requirements

Requires a practicing lawyer's qualification + basic low-code/no-code tool usage skills (such as Dify, n8n). Month 1: Complete the organization and vectorization of 10-20 vertical industry contract templates, local regulations, and case precedents. Month 2: Build the SaaS frontend (WeChat Mini Program/H5) and payment gateway. Lawyers without technical capabilities can spend RMB 2,000-5,000 to outsource frontend development. The overall setup period is 1.5-2 months.

🧰 Toolchain

🔧 Dify
🔧 n8n
🔧 Claude or Tongyi Qianwen LLM API

💰 Revenue

① Micro and small enterprises in vertical industries such as decoration, education and training, and cross-border trade subscribe monthly to the contract review SaaS (Main Revenue): Business clients subscribe and pay monthly, RMB 399-799/month × 50-80 paying enterprises = monthly revenue of about RMB 20,000-64,000, accounting for roughly 100% of monthly revenue (estimated by range, based on operator self-reports without independent verification); ② High-ticket subscriptions in head vertical scenarios: Cross-border trade compliance clients subscribe monthly at RMB 1,299/month × number of signed clients (unverifiable, though internal cards claim monthly revenue can exceed RMB 60,000; its weight in total revenue is unspecified, also based on operator self-reports); ③ ASEAN legal corpus and compliance knowledge base licensing: Licensing fees charged per database/year to cross-border trade enterprises and law firms. Sources state its corpus includes over 190,000 laws and regulations from 11 ASEAN countries and over 500 million characters of text (these scale figures come from the company's external releases); licensing prices and actual signing volumes are unverified, and market share is unknown; ④ Opportunity items - Pay-per-use for vertical industry contract template packages and compliance plugins; no data yet on revenue generation.

💸 Cost

Monthly costs are approximately RMB 4,000-6,000, of which LLM API call fees (contract parsing, review generation) account for RMB 2,000-3,000/month, cloud server and object storage fees account for RMB 500-800/month, SaaS tool subscriptions (Dify, n8n Enterprise Edition) account for RMB 400-600/month, with no additional personnel costs.

⏱ Time Investment

Initial setup period is 1.5-2 months; daily operations require 1-3 hours, including 1 hour updating the knowledge base, 1 hour reviewing AI review results, and the remaining time expanding clients and handling after-sales service.

🚀 Getting Started

Step 1: Select 1 vertical niche industry (prioritizing fields with strong rigid demand and scarce legal resources, such as decoration, education and training, and ASEAN cross-border trade), and organize at least 10 real business contract templates and local compliance precedents. Step 2: Use Dify to build a contract knowledge base, integrate LLM API to configure review rules, deploy the WeChat Mini Program frontend, and open the payment gateway. Step 3: Promote through bar associations, industry chambers of commerce, and entrepreneur communities, with an initial subscription price of RMB 399/month, offering the first 100 clients 1 complimentary manual lawyer review benefit.

🔑 Keys to Success

✅ Lawyer IP authority and real case library endorsement to build client trust
✅ Depth and continuous coverage of vertical industry contract templates to match niche scenario demands
✅ Manual lawyer review of AI high-risk clauses as the final safeguard, implementing a human-in-the-loop judgment model
✅ SaaS subscription renewal and referral mechanism design to enhance client lifetime value

⚠️ 风险

⚠️ AI review omission risks may trigger contract disputes, and lawyers still bear legal liability for final opinions
⚠️ Subscription stickiness heavily relies on the continuous updating of the template library; if not updated promptly, the churn rate can exceed 40%
⚠️ LLM hallucinations may lead to misjudgment of compliance clauses; if lawyer review is negligent, it may trigger law firm practice liability risks
