AI Automation/Legal

Automate Contract Review for Your Law Firm with Compliant AI

Law firms use AI to extract clauses and flag non-standard terms against a firm's internal library. Compliance is managed with audit trails and human-in-the-loop gates before any action is taken.

Syntora helps law firms automate contract review by building custom AI systems that extract clauses and flag non-standard terms. Syntora would engineer a secure, private cloud solution tailored to the firm's specific contract types, leveraging existing AI models and auditable workflows.

Building an AI-powered contract review system involves understanding the specific types of contracts a firm handles and the allowable variation in their standard clauses. For example, a system for a firm reviewing a single, highly standardized agreement like a commercial lease would be a more direct initial build compared to one for a firm managing multiple M&A document types with complex dependencies. Syntora's approach ensures all privileged client documents remain within your private infrastructure.

The Problem

What Problem Does This Solve?

Many firms first look at off-the-shelf Contract Lifecycle Management (CLM) software. These platforms are built for legal departments with hundreds of attorneys and come with enterprise-level pricing, often with mandatory per-seat licenses. Their AI is a black box, offering no way to tune clause detection to your firm’s specific language or risk tolerance. Crucially, they often require you to upload client documents to their cloud, creating serious compliance and privilege issues.

A common next step is experimenting with general document AI tools. Using a public API like OpenAI's for client work is a non-starter due to data privacy policies. Even with private models, the core problem remains: they are not trained on your firm's unique playbook. This creates a flood of false positives. We saw a 12-person firm try this for reviewing vendor agreements; the AI flagged 80% of the clauses in their own paper as 'non-standard' because it was comparing them to a generic, public template.

These approaches fail because they treat legal document review as a generic text analysis problem. They lack the built-in audit trails, human review gates, and on-premise data security that law firms require. The time spent dismissing irrelevant AI-generated flags ends up being more work than a manual review.

Our Approach

How Would Syntora Approach This?

Syntora approaches contract review automation by first collaborating with your firm to define and codify its expertise. The initial step would involve your team providing 50-100 examples of your firm's gold-standard contracts and any non-standard variations for training. Syntora would then ingest these documents to build a dedicated clause library within a Supabase Postgres database, incorporating vector embeddings for semantic search. This library, deployed within your cloud account, would serve as the core reference for all automated reviews.

Next, Syntora would design and build a FastAPI service to manage the entire contract review workflow. When a contract arrives, perhaps as a PDF email attachment, an AWS Lambda function would securely save it to your private AWS S3 bucket. This function would use Amazon Textract for optical character recognition (OCR) and then send the extracted text to the Claude API. A carefully crafted prompt directs the Claude API to extract key clauses as structured JSON data. We have experience building similar document processing pipelines using Claude API for sensitive financial documents, and the same robust pattern applies here.

The FastAPI service would then compare each extracted clause against your firm's Supabase library. We would implement a hybrid search mechanism to identify the closest approved standard clause. Any clause deviating significantly from the standard or identified as entirely new would be flagged. The system would compile a summary report, detailing each flagged item, the AI's confidence score, and providing a direct link to the relevant section of the original document. This report would be routed to the responsible attorney for review.

Finally, Syntora would develop a custom review interface, potentially using Vercel, to facilitate attorney oversight. This interface would present a side-by-side view of flagged clauses alongside your firm's standard language. Attorneys would make the final decision with a simple action to approve or reject the deviation. All decisions would be logged in a permanent audit trail within Supabase, establishing a defensible record of the review process. A typical engagement to build such a system, including discovery, architecture, and initial deployment, often spans 8-12 weeks, depending on the number of contract types and custom integrations required.

Why It Matters

Key Benefits

01

Review a 20-Page Lease in 90 Seconds

Free your paralegals from manual clause comparison. The system extracts, compares, and flags deviations in under two minutes, turning 45-minute reviews into quick approvals.

02

No Per-Seat Fees, Just Cloud Costs

Avoid expensive CLM software subscriptions. After our one-time build, your only recurring cost is for cloud usage, typically under $50 per month on AWS for processing hundreds of documents.

03

You Own The Code And Clause Library

The entire system is deployed in your AWS account and the code is delivered to your GitHub. Your firm's intellectual property, your clause library, remains yours permanently.

04

Every AI Decision Has an Audit Trail

We log every clause extraction and comparison with a confidence score. The human-in-the-loop gate ensures an attorney signs off on every flagged item, creating a defensible review process.

05

Connects Directly to Your Email Intake

No new software for your team to learn. Contracts arrive as email attachments, and review summaries are sent back to the assigned attorney's inbox automatically.
