"content": "Most people sign contracts and terms of service without reading every clause, and problems only surface once it is too late to negotiate. This workflow reads any pasted contract, lease, NDA, or terms of service and returns a plain English risk report in under a minute. It is built for freelancers, renters, employees, and small business owners who want to know what they are agreeing to before they sign. The output is not legal advice, it is a starting point for asking better questions.\n\n### How it works\n1. The Form Trigger collects the contract text, the person's role, and an optional document type.\n2. Map Form Fields cleans the submitted data into simple fields.\n3. Long Enough? checks there is enough text to analyze, short submissions get a friendly error instead of wasting a request.\n4. Prepare Input trims very long contracts so they stay inside the AI model's limits.\n5. Analyze Contract sends the text to the AI model, which returns a risk score, summary, and flagged clauses.\n6. Build HTML Report formats that data into a report, and Send Report shows it back to the user right away.\n\n### Setup steps\n1. Open the OpenAI Chat Model node (node 7) and connect your own OpenAI credential. Any Chat Model node works the same way for Anthropic or Gemini.\n2. No other credentials or placeholders are needed.\n3. Activate the workflow, then open the Form Trigger's production URL and test it with a real contract.\n\n### Customization\nAdjust the 200 character minimum in Long Enough? for stricter or looser validation. Change the risk categories or the prompt in Analyze Contract to match a specific industry."
