Document Chat AI: Talk to Your Contracts Like a Lawyer

How many times have you stared at a 50-page contract wondering "When does this renew?" or "What's my cancellation policy?" Reading every clause is time-consuming. Missing a key detail is expensive. Document Chat AI solves both problems.

What is Document Chat AI?

Document Chat AI uses large language models (like GPT-4) to understand your documents and answer questions in natural language. Think of it as having a lawyer on standby who's read every contract you've ever signed.

How It Works

1. Upload Document

```javascript

const document = await client.documents.upload({

file: './vendor-contract.pdf',

title: 'Software Vendor Agreement'

});

```

2. AI Analyzes Content

3. Ask Questions in Plain English

```javascript

const response = await client.ai.chat({

documentId: document.id,

question: "When does this contract auto-renew?"

});

console.log(response.answer);

// "This contract auto-renews annually on January 1st

// unless cancelled with 90 days written notice. See

// Section 12.3 'Term and Termination' for details."

```

Practical Examples

Example 1: Understanding Termination Rights

Question: "Can I cancel this contract early, and if so, what's the penalty?"

AI Response:

```

Yes, early termination is allowed under Section 8.2 "Termination for Convenience."

Termination Terms:

• You may terminate with 60 days written notice

• Early termination fee: $5,000 or 3 months of service fees (whichever is less)

• Must return all confidential information within 10 days

• Prepaid fees are non-refundable

To terminate, send written notice to: contracts@vendor.com

Relevant Sections:

• Section 8.2 - Termination for Convenience

• Section 11.4 - Return of Materials

• Section 6.1 - Fees and Payment Terms

Confidence: 95%

```

Example 2: Liability Analysis

Question: "What's our maximum liability exposure under this contract?"

AI Response:

```

Your maximum liability is capped at $100,000 (see Section 9.3).

Exceptions (unlimited liability):

• Breach of confidentiality obligations

• Intellectual property infringement

• Gross negligence or willful misconduct

• Death or bodily injury

Note: Customer's liability is capped at total fees paid in

previous 12 months, which creates an asymmetric risk.

Recommendation: Consider negotiating equal liability caps.

Confidence: 98%

```

Example 3: Data Privacy Compliance

Question: "Does this vendor agreement comply with GDPR?"

AI Response:

```

Partial compliance detected. Missing key GDPR requirements:

✅ Present:

• Data processing purposes defined (Section 5.1)

• Security obligations (Section 7.2)

• Notification of breaches within 72 hours (Section 7.4)

❌ Missing:

• No Data Processing Agreement (DPA) attached

• Sub-processor list not provided

• No mention of data subject rights (access, deletion)

• Data transfer mechanisms unclear for EU data

Recommendation: Request GDPR-compliant DPA addendum before signing.

Risk Level: High (GDPR violations = 4% global revenue penalty)

Confidence: 92%

```

Advanced Features

1. Multi-Document Queries

Compare terms across multiple contracts:

```javascript

const comparison = await client.ai.compareDocuments({

documents: [contract1, contract2, contract3],

question: "Which contract has the most favorable payment terms?"

});

/ Response:

Contract B offers the best terms:

• Net 60 (vs Net 30 for A, Net 45 for C)

• No late payment penalties (A and C charge 1.5%/month)

• Early payment discount: 2% if paid within 10 days

However, Contract B has higher overall pricing (+15% vs Contract A).

/

```

2. Risk Detection

Automatically flag high-risk clauses:

```javascript

const risks = await client.ai.analyzeRisks(document.id);

/ Response:

HIGH RISK:

• Unlimited liability for IP infringement (Section 9.2)

• Auto-renewal with 180-day notice period (Section 12.1)

• Exclusive venue in vendor's jurisdiction (Section 15.3)

MEDIUM RISK:

• Broad confidentiality definition (Section 6.1)

• No SLA or performance guarantees

• Price increase rights without cap (Section 4.3)

LOW RISK:

• Standard termination clauses

• Reasonable warranty terms

/

```

3. Clause Extraction

Pull specific clause types across documents:

```javascript

const clauses = await client.ai.extractClauses({

documents: allVendorContracts,

clauseTypes: [

'indemnification',

'limitation of liability',

'termination',

'data protection'

]

});

// Export to spreadsheet for comparison

exportToExcel(clauses);

```

4. Timeline Extraction

Build calendar of important dates:

```javascript

const timeline = await client.ai.extractDates(document.id);

/ Response:

{

"effectiveDate": "2026-01-01",

"initialTermEnd": "2027-01-01",

"renewalNoticeDeadline": "2026-10-03",

"paymentDue": "15th of each month",

"auditRights": "Annual, with 30 days notice",

"terminationNotice": "90 days"

}

/

```

Building a Document Chat Integration

Basic Implementation (Node.js)

```javascript

const SpaceSign = require('@spacesign/sdk');

const client = new SpaceSign({

apiKey: process.env.SPACESIGN_API_KEY

});

async function chatWithDocument(documentId, question) {

try {

const response = await client.ai.chat({

documentId,

question,

options: {

includeReferences: true, // Include section citations

confidence: 0.8, // Minimum confidence threshold

maxTokens: 500 // Response length limit

}

});

return {

answer: response.answer,

confidence: response.confidence,

references: response.references,

highlights: response.highlights

};

} catch (error) {

console.error('AI chat error:', error);

throw error;

}

}

// Usage

const result = await chatWithDocument(

'doc_123',

'What is the cancellation policy?'

);

console.log(result.answer);

console.log('Confidence:', result.confidence);

console.log('Source:', result.references[0].section);

```

Frontend Chat Interface (React)

```jsx

import { useState } from 'react';

function DocumentChat({ documentId }) {

const [messages, setMessages] = useState([]);

const [input, setInput] = useState('');

const [loading, setLoading] = useState(false);

const sendMessage = async () => {

if (!input.trim()) return;

// Add user message

setMessages([...messages, { role: 'user', content: input }]);

setInput('');

setLoading(true);

try {

// Get AI response

const response = await fetch('/api/document-chat', {

method: 'POST',

headers: { 'Content-Type': 'application/json' },

body: JSON.stringify({ documentId, question: input })

});

const data = await response.json();

// Add AI response

setMessages(prev => [...prev, {

role: 'assistant',

content: data.answer,

confidence: data.confidence,

references: data.references

}]);

} catch (error) {

console.error('Chat error:', error);

} finally {

setLoading(false);

}

};

return (

<div className="document-chat">

<div className="messages">

{messages.map((msg, i) => (

<div key={i} className={\`message \${msg.role}\`}>

<p>{msg.content}</p>

{msg.references && (

<div className="references">

{msg.references.map(ref => (

<span className="reference">{ref.section}</span>

))}

</div>

)}

</div>

))}

{loading && <div className="loading">AI is thinking...</div>}

</div>

<div className="input">

<input

value={input}

onChange={(e) => setInput(e.target.value)}

onKeyPress={(e) => e.key === 'Enter' && sendMessage()}

placeholder="Ask a question about this document..."

/>

<button onClick={sendMessage}>Send</button>

</div>

</div>

);

}

```

Best Practices

1. Ask Specific Questions

❌ Vague: "Tell me about this contract"

✅ Specific: "What is the monthly payment amount and due date?"

❌ Too Broad: "What are the terms?"

✅ Focused: "What are the termination terms for this agreement?"

2. Verify Critical Information

Always double-check AI responses for high-stakes decisions:

```javascript

// Get AI answer

const aiResponse = await client.ai.chat({

documentId,

question: "Can we terminate without penalty?"

});

// Highlight relevant sections for human review

const verification = await client.documents.highlight({

documentId,

sections: aiResponse.references

});

// Human reviews highlighted sections

```

3. Use Confidence Scores

```javascript

const response = await client.ai.chat({ / ... / });

if (response.confidence < 0.8) {

// Low confidence - flag for human review

await notifyLegal({

question: question,

aiResponse: response.answer,

confidence: response.confidence,

reason: 'Low confidence score - needs verification'

});

}

```

4. Maintain Audit Trails

Log all AI interactions for compliance:

```javascript

await auditLog.create({

action: 'document_ai_query',

user: currentUser.id,

documentId: documentId,

question: question,

answer: response.answer,

confidence: response.confidence,

timestamp: new Date()

});

```

Predictive Analytics:

"Based on similar contracts, there's an 80% chance the vendor will agree to Net 60 payment terms if you request it."

Automated Negotiation:

"This clause is unfavorable. Here's suggested alternative language that protects your interests..."

Cross-Reference Intelligence:

"This NDA conflicts with your master services agreement signed last year. Recommend revisions..."

Workflow Automation:

"Contract expires in 90 days. Auto-draft renewal memo? Draft termination notice? Set calendar reminder?"
