How I Built an AI Contract-Analyzing Agent Inside Slack in Airia

Manually reviewing contracts is slow, expensive, and error-prone. Whether you’re a business owner, legal professional, or agency founder, reading lengthy agreements line by line drains valuable time—and still leaves room for risk. Learn how to build an AI contract-analyzing agent inside Slack using Airia, including setup, model configuration, and real-world deployment steps.

That’s exactly why I decided to build an AI-powered contract-analyzing agent inside Slack using Airia. The goal was simple:
Upload a contract (PDF) to Slack
Instantly analyze it with AI
Receive a risk score out of 100
Flag fraudulent or dangerous clauses automatically

If you want to build AI agents like this without heavy coding, Airia makes the entire process incredibly simple. From model setup to secure Slack deployment, everything is managed in one clean dashboard. 👉 Join Airia now and start building AI agents in minutes instead of weeks.

In this full walkthrough, I’ll show you exactly how I built it, step by step—no fluff, no theory. This is a real production-ready AI agent you can replicate for your own business or clients.

What This AI Contract Agent Does

Before diving into the build, here’s what the agent actually accomplishes:

• Accepts PDF contract uploads directly in Slack
  
• Analyzes legal language using a powerful LLM
  
• Flags fraudulent, risky, or unfair clauses
  
• Generates a risk score (0–100)
  
• Summarizes whether the contract is safe to sign
  
• Works inside Slack as a dedicated AI bot
  

This makes it ideal for:

• Businesses reviewing contracts daily
  
• Agencies adding AI solutions to their service stack
  
• Internal legal or compliance teams
  
• AI builders looking for real enterprise use cases
  

Why I Chose Airia for This Build

Airia is a no-code / low-code AI agent platform designed specifically for secure, enterprise-grade agents.

Here’s why it stood out:

• Clean, organized project structure
  
• Easy model and API key management
  
• Strong security and data guardrails
  
• Native integrations (like Slack)
  
• Ability to deploy agents quickly without custom backend code
  

If you’re building AI agents for real businesses—not just demos—Airia is built for that level of reliability. One of the biggest advantages of using Airia is how easily you can manage AI models and API keys across multiple projects. You add your key once and reuse it everywhere—no repeated setup, no confusion. Sign up for Airia today if you want a scalable and production-ready AI workflow.

Step 1: Create Your Airia Account

Start by visiting airia.com and creating a free account.

Once logged in, you’ll notice the interface feels familiar if you’ve used other no-code tools. Everything is clean, modular, and project-based—which makes scaling later much easier.

Step 2: Connect Your AI Model (Anthropic Claude)

Before building the agent, we need to connect a model.

How I did it:

1. Navigate to Components → Models
   
2. Select Anthropic
   
3. Choose Claude 3 Sonnet (or equivalent)
   
4. Click Add
   
5. Create a new credential
   
6. Paste your Anthropic API key
   
7. Save the configuration
   

One of Airia’s biggest advantages is that API keys are stored once and reused across projects, making long-term maintenance far easier. If you’re new to building AI agents and want a faster starting point, check out our detailed guide on Build an AI Agent in Minutes with Airia. It walks you through the basics of creating, configuring, and deploying AI agents step by step—making it the perfect companion to this advanced Slack-based contract analysis workflow.

Step 3: Create a New Project and Agent

Now it’s time to build.

1. Create a new project (I named mine something like “PDF Contract Analysis”)
   
2. Click Add New Agent
   
3. You’ll see three core blocks:
   
   • Input
     
   • Model
     
   • Output
     

Airia also allows advanced features like:

• Knowledge bases
  
• Tools
  
• Flow control
  
• Human-in-the-loop
  
• Custom memory
  

For this use case, we keep it lean and focused.

Step 4: Configure Agent Inputs

Contracts are uploaded as PDFs, so we need:

• Text input
  
• File attachments enabled
  

Airia automatically detects what the selected model supports, so no manual configuration is required here.

Step 5: Model Settings (Accuracy Over Creativity)

Since this is legal analysis, we prioritize accuracy and consistency.

Recommended settings:

• Include user input ✔️
  
• Include attachments ✔️
  
• Include full chat history ✔️
  
• Temperature: slightly lowered (to reduce hallucinations)
  
• Reasoning effort: Balanced
  

This ensures the AI behaves more like a legal analyst than a creative writer.

Step 6: Write the Contract Analysis Prompt

This is the brain of the agent.

Inside the Prompt Editor, I added a custom system prompt that instructs the AI to:

• Analyze the uploaded contract in detail
  
• Identify risky or fraudulent clauses
  
• Flag unfair terms
  
• Provide a clear summary
  
• Output a risk score out of 100
  
• Clearly advise whether the contract is safe to sign
  

The prompt also controls formatting so the output is:

• Structured
  
• Easy to scan
  
• Actionable
  

Once saved, the agent is ready for testing.

Step 7: Test the Agent in Airia Playground

Airia includes a built-in Playground for testing before deployment.

I uploaded a test contract PDF and typed:

“Analyze”

Within seconds, the agent returned:

• A risk score
  
• A breakdown of dangerous sections
  
• A clear summary explaining why the contract was risky
  

In my test, the AI correctly identified intentionally planted fraudulent clauses—proving the setup worked exactly as intended.

Step 8: Prepare the Agent for Slack Deployment

Now comes the fun part—embedding the AI inside Slack.

1. Name the agent (e.g., “Contract Agent”)
   
2. Go to Interfaces
   
3. Select Slack Bot
   
4. Create a new Slack credential (token added later)
   

Airia makes multi-interface deployment extremely simple, which is a huge advantage over custom-coded bots.

Step 9: Create a Slack App

Next, we configure Slack.

Steps:

1. Visit the Slack API dashboard
   
2. Create a new app “From Scratch”
   
3. Name it (e.g., Contract Agent)
   
4. Select your workspace
   

Enable the following:

• Agents & AI Apps
  
• App Home messaging
  
• Required OAuth scopes (message access, file access, DMs)
  

Install the app to your workspace and copy the Bot User OAuth Token.

Step 10: Connect Slack to Airia

Back inside Airia:

1. Paste the Slack bot token into the credential
   
2. Save the deployment
   
3. Copy the Webhook Events API URL
   

Back in Slack:

1. Enable Event Subscriptions
   
2. Paste the webhook URL
   
3. Subscribe to message.im events
   
4. Save changes
   

At this point, Slack and Airia are fully connected.

Step 11: Test the AI Agent Inside Slack

Open Slack and search for your new app.

Start a conversation and type a simple message like:

“Hey”

If configured correctly, the bot responds and introduces itself.

Now upload a contract PDF directly into the chat and type:

“Analyze please”

Within moments, the AI:

• Processes the file
  
• Analyzes every clause
  
• Returns the risk score
  
• Flags dangerous sections
  
• Clearly warns if the contract should not be signed
  

All of this happens inside Slack, using the native file uploader.

If Slack is where your team already works, Airia’s native Slack integration is a game-changer. You can turn powerful AI agents into Slack bots without building custom backends or writing complex code. Join Airia now and bring AI directly into your daily workflows.
