Preparing Contracts for AI Comparison

Getting contracts ready for AI analysis is a crucial step. The quality of your input directly influences how well the AI performs, especially when comparing different contract versions. Proper preparation ensures the process is both accurate and efficient.

Using Compatible File Formats

Choosing the right file format can make all the difference. Most platforms work seamlessly with DOCX, PDF, and TXT formats, but many advanced tools can also handle HTML, RTF, ODT, EPUB, JSON, CSV, and XML files.

Formats like HTML, XML, or Markdown are particularly effective because they eliminate the need for optical character recognition (OCR), speeding up the process and reducing errors. If you're working with scanned documents, aim for a resolution of at least 200 dpi, though 300 dpi or higher yields the best results.

For older contracts in unsupported formats, convert them into machine-readable ones. Whenever possible, use the original source document and export it into a supported format. This simple step can significantly improve how well the AI understands the content.

To further enhance readability, structure your contracts with plain language, clear headings, and well-defined key terms. While AI tools have advanced in recognizing document structure, providing clean and organized formatting gives them a much-needed boost.

Once the files are ready, the next step is organizing them effectively.

Organizing Document Versions

Good organization is the backbone of accurate AI analysis. Even the most sophisticated AI tools can struggle if files are poorly labeled or stored. Start with systematic labeling and filing practices that prioritize easy access and searchability.

A straightforward way to manage contracts is by assigning unique IDs. For instance, a contract labeled 'NDA-2025-040' immediately identifies it as a Non-Disclosure Agreement signed in 2025 with a serial number of 40. This kind of naming convention eliminates confusion and speeds up retrieval.

For storage, a hierarchical system works best. Organize files by categories like "Year/Contract Type/Contract", creating logical pathways that both humans and AI can navigate easily. Pair this with centralized, paperless storage systems to maintain a single, reliable source of truth.

Adding metadata fields transforms contracts into searchable, trackable assets. Key fields might include:

Metadata Field	Purpose	Example
Contract Owner	Assigns responsibility	John Doe (Legal Team)
Contract Type	Categorizes for easy lookup	NDA, MSA, Employment
Execution Date	Notes when the contract was signed	02/01/2023
Renewal/Expiration Date	Tracks renewals or expirations	02/01/2026
Contract Value	Aids in financial tracking	$100,000
Notice Period	Helps manage terminations	60 days
Counterparty Name	Identifies the other party involved	ABC Corp

With proper formats and organization in place, the next critical step is ensuring strong data security.

Data Security and Compliance Requirements

Once your contracts are well-prepared, safeguarding sensitive data becomes a top priority. Legal documents often contain confidential information, making data security and confidentiality essential during AI analysis.

It's also important to comply with regulations like GDPR, which emphasize data minimization and transparency around how data is collected and used. These measures help protect sensitive information while maintaining trust.

Step-by-Step Guide: Comparing Contract Versions with AI Tools

With your contracts prepped and ready, it's time to let AI do the heavy lifting. While the process is straightforward, understanding each step ensures you catch important changes and get the most accurate results.

Uploading and Selecting Contracts

Start by uploading the different versions of your contract to your chosen AI platform. Most modern tools handle a variety of file formats - like DOCX, PDF, or HTML - and use this input to extract and analyze clauses. This step is crucial for spotting risks or unfamiliar terms that might otherwise slip through the cracks.

When uploading, avoid vague instructions like "compare these contracts." Instead, give clear, specific prompts. For example, you might direct the AI to focus on liability clauses, payment terms, or termination conditions. Many platforms even offer preset playbooks to help standardize your review process.

Before rolling out the AI across your entire portfolio, test it with a small set of sample contracts. This approach ensures the tool works as expected. For instance, a B2B SaaS company reported cutting review time by 70% while streamlining their third-party agreements.

Once your contracts are uploaded and your prompts are set, move on to reviewing the AI-generated redlines.

Reviewing AI-Generated Redlines and Change Summaries

After processing, the AI will generate redlines and a summary of the changes it found. These tools highlight additions, deletions, and modifications, even recognizing reworded clauses or structural shifts that could change the meaning of the agreement - details that manual reviews often miss.

It's important to verify critical edits flagged by the AI. Double-check laws, definitions, and referenced facts, as the AI might occasionally misinterpret complex legal concepts or rely on outdated statutes. Pay particular attention to significant changes, like liability limits, to ensure they align with your organization's risk tolerance. Adjust the tone of the document to match your firm's style and document key changes along with the reasoning behind them. If the AI's results seem off, refine your query and run the comparison again.

Using Filters and Search Features for Key Changes

Most AI contract platforms include advanced search and filtering tools, which make it easy to zero in on specific details. For instance, you could search for "indemnity clauses expiring in 90 days" to quickly locate relevant terms. These tools allow you to efficiently review key clauses without combing through the entire document.

Filters also let you narrow your focus to specific agreement types, saving time during reviews and negotiations. This capability is especially helpful during audits or legal reviews, where quick access to relevant clauses is critical. Just remember to clear any previous filters before starting a new search to avoid confusion.

Platforms like Docgic showcase these features with advanced document comparison tools and citation-backed change tracking. Their system combines legal-grade security with powerful search and filtering options, making it easier for legal teams to stay efficient. By pairing AI’s ability to identify and categorize changes with human oversight, your team can focus on strategic decisions while leaving the tedious work to the AI.
