Automating Contract Due Diligence: 9-Vector Risk Audits with ClauseGuard AI
Commercial agreements, freelance scopes, NDAs, and software licensing contracts frequently hide predatory termination clauses, one-sided indemnity waivers, and unlimited liability obligations. For founders, independent consultants, and procurement teams lacking dedicated in-house counsel, signing without rigorous review invites catastrophic exposure.
To democratize institutional-grade legal diligence, we engineered [ClauseGuard AI](https://kreggscode.com/apps/clauseguard/)—a native iOS legal intelligence platform that audits legal documents in seconds against 9 diligence vectors and generates attorney-grade counter-proposal redlines.
ClauseGuard AI is available live on the Apple App Store:

1. The 9 Diligence Vectors of Legal Risk
Rather than running generic LLM prompts that produce conversational legal summaries, ClauseGuard enforces a deterministic 9-Vector Risk Taxonomy:
┌────────────────────────────────────────────────────────┐
│ ClauseGuard 9-Vector Taxonomy │
└────────────────────────────────────────────────────────┘
1. Unlimited Liability & Damages Caps
2. One-Sided Indemnification Obligations
3. Unilateral Termination for Convenience
4. Non-Compete & Restrictive Covenant Overreach
5. IP Assignment & Pre-Existing Work Ownership
6. Automatic Renewal & Lock-In Clauses
7. Payment Terms, Net-D Days & Audit Penalties
8. Governing Law & Unfavorable Arbitration Venues
9. Data Privacy, Confidentiality & Breach Notice Periods---
2. On-Device PDFKit & Parsing Engine
Legal agreements often contain complex multi-column typography, dense headers/footers, and watermarks. ClauseGuard utilizes Apple's native PDFKit alongside an isolated spatial tokenizer to preserve section hierarchies and clause numbering:
import PDFKit
import Foundation
struct ContractSection: Identifiable {
let id = UUID()
let clauseNumber: String
let heading: String
let rawText: String
let riskScore: Double
}
final class ContractDocumentParser {
static func extractClauses(from pdfDocument: PDFDocument) -> [ContractSection] {
var sections: [ContractSection] = []
let pageCount = pdfDocument.pageCount
var fullText = ""
for index in 0..<pageCount {
guard let page = pdfDocument.page(at: index),
let text = page.string else { continue }
fullText += text + "\n"
}
// Segment clauses using legal regex patterns
let clauseRegex = try! NSRegularExpression(
pattern: #"(?m)^(?:\d+\.|\([a-z]\)|SECTION\s+\d+)[\s\t]+(.+)
