Intelligent Contract Audit Agent: Risk Detection with Claude + n8n
What This Workflow Does
This workflow acts as a 24/7 legal assistant. It monitors a shared folder for new PDF contracts, extracts all text using OCR, and uses claude-3-5-sonnet to identify 'high-risk' clauses like auto-renewals, non-competes, or unfavorable liability terms.
Who It's For
Finance teams, Operations managers, and Legal departments handling 20+ vendor contracts a month who need to ensure compliance without expensive legal fees for every review.
What You'll Need
- n8n account
- Anthropic API key
- Google Drive or Dropbox access
- OCR tool (n8n built-in or AWS Textract)
- Estimated setup time: 90 minutes
What You Get
- Instant 'Risk Score' for every contract
- Red-flag list of clauses that need negotiation
- Automated summary of key dates (expiration, notice periods)
- Saves 8-10 hours/week of manual document review
The Workflow
Monitor Document Folder
Trigger the workflow whenever a new file is uploaded to a specific 'To Review' folder in Google Drive or Dropbox.
Watch out: Only trigger on .pdf or .docx files. Add a filter to ignore temporary or system files.
Extract Text via OCR
Use n8n's built-in OCR node or connect to AWS Textract to convert the PDF into clean, structured text. This is crucial for scanned contracts.
Watch out: High-resolution scans (300 DPI) are necessary for 99% accuracy. Low-quality photos will result in AI 'hallucinations'.
Audit for Red-Flag Clauses
Send the extracted text to claude-3-5-sonnet. Provide a list of 'Forbidden' or 'High-Risk' clauses your company avoids. Ask Claude to locate them and explain why they are risky.
Watch out: Use a 'Chain of Thought' prompt where the AI must quote the specific text from the contract before providing its analysis.
Extract Key Dates & Metadata
In a parallel step, have Claude extract 'Action Dates' like termination notice periods, contract end dates, and payment terms into a structured format.
Watch out: Format the dates as ISO strings (YYYY-MM-DD) so they can be easily pushed to a calendar or database.
Generate Audit Report & Alert
Compile the Red Flags and Key Dates into a clean PDF or Google Doc. Send an urgent Slack alert if the Risk Score is high (>7), otherwise just email the summary.
Watch out: Include a link to the original file in every alert so the reviewer doesn't have to hunt for it.
Workflow Insights
Deep dive into the implementation and ROI of the Intelligent Contract Audit Agent: Risk Detection with Claude + n8n system.
Yes, this workflow is designed with architectural clarity in mind. Most users can implement the core logic within 45-60 minutes using the provided steps and tool recommendations.
Absolutely. The blueprint provided is modular. You can easily swap tools or modify individual steps to fit your unique operational requirements while maintaining the core algorithmic efficiency.
Based on current benchmarks, this specific system can save approximately 10 hours/week hours per week by automating repetitive tasks that previously required manual intervention.
The tools vary. Some are free, while others may require a subscription. We always try to recommend tools with generous free tiers or high ROI to ensure the automation remains cost-effective.
We recommend reviewing each step carefully. If you encounter issues with a specific tool (like Zapier or OpenAI), their respective documentation is the best resource. You can also reach out to the Dailyaiworld collective for architectural guidance.
