The Problem & The Solution
The Problem
Contract review costs **$300–$600 per hour**. Most small businesses, startups, and freelancers simply cannot afford it.
Because of this high entry barrier, most people end up signing complex legal contracts blindly, without fully understanding what clauses they are agreeing to.
The Solution
RedlineAI reads any legal contract, identifies every risky clause, explains each one in plain English, assigns a risk level of Low, Medium, or High, and delivers a full professional risk report to the user's inbox in **under 30 seconds**.
Runs fully autonomously for **under 5 cents** per analysis.
How It Works
Two Modes. Two AI Approaches.
RedlineAI operates under two distinct models: an automated web-based serverless pipeline and a local developer agent mode.
The n8n Workflow
The Automated Pipeline — Inside n8n
The entire backend runs inside n8n — a visual workflow automation tool. Six nodes run in sequence, fully automatically, without any human involvement.
Webhook
Receives the contract submission payload from Fillout. The entry point of the entire workflow.
Download Contract
Downloads the PDF file from Fillout storage as binary data privately inside n8n.
PDF Text Extractor
Converts the binary PDF into plain readable text using n8n's native extraction tool. No external service. Completely private.
Risk Analyzer
GPT-4.1 Mini reads the full contract text and produces a structured risk report with clause-by-clause analysis and an overall risk level.
Save to Airtable
The full report, contract name, date, and risk level are saved permanently to the Airtable database.
Send a Message
A personalized professional email with the full risk report is delivered automatically to the user's inbox.

MCP Explained
What Is MCP and Why Does It Matter?
MCP stands for Model Context Protocol. It is a standard that gives AI models like Claude access to external tools — file systems, databases, and APIs.
Without MCP, Claude can only respond to text you paste into the chat. With MCP, Claude can reach out and use tools autonomously. MCP is the pair of hands for Claude. In RedlineAI Option B, Claude uses the Filesystem MCP tool to find and read a contract file directly from a folder on the user's Mac — without any manual uploading or copy-pasting. That is the difference between a chatbot and a true AI agent.
