ReviewPartner™

AI-Powered, Human-Supervised Document Review

Review Partner

Faster Delivery, Better Results, Lower Costs

ReviewPartner transforms document review from an expensive, time-consuming process into a smarter, more efficient AI-powered workflow. Our hybrid approach combines advanced AI technology with expert human oversight to deliver faster, better results with substantial cost savings.

  • Responsive Review: Identify responsive documents, provide review analysis and issue identification.
  • Privilege Review: Identify privileged and non-privileged communications and potential work product; provide classification reasoning. 
  • Specialized Review: Custom reviews for contracts, issue tracking, investigations, or other specific information needs.

All three review types follow our unique four-stage process designed to ensure accurate, consistent, and defensible results. Leading generative AI models combined with proprietary machine learning algorithms analyze documents at a fraction of the cost for manual review. Unlike humans, AI doesn’t suffer from fatigue or distraction—it applies the same criteria to document 100,000 as it did to document one. It’s a smarter approach—maintaining superior accuracy with unmatched consistency in review judgments.

Even Smarter Review with CAL

For large document collections, Continuous Active Learning (CAL) can dramatically reduce review costs by prioritizing documents by likely relevance. (Our CAL algorithm can analyze and rank a million documents in 100 milliseconds—the fastest in the industry.) Once the relevance level drops to an appropriate level, you can stop the review early—a practice courts have repeatedly approved for Technology Assisted Review.

In low-richness collections, this can mean reviewing as few as 10% of the documents while still meeting defensibility standards. We use elusion testing to validate that unreviewed documents are unlikely to contain responsive material. The result: lower review costs through an even smarter, defensible review process.

The ReviewPartner Advantage

Speed

Complete reviews in days, not weeks. AI can review thousands of documents per hour with unflagging attention to detail.

Accuracy

Consistent application of review criteria across every document. No fatigue, no variation in judgment from first document to last.

Savings

Substantial cost reductions compared to human review teams. No hourly reviewer charges. Pay for results, not time.

Defensibility

Rigorous validation protocols provide statistical certainty for both linear and CAL reviews. Senior reviewers validate AI judgments at each stage.

This isn’t AI replacing humans. It’s about using AI to augment the judgment of senior reviewers.

Merlin's Unique Four-Stage Review Process

ReviewPartner follows a rigorous four-stage protocol designed to ensure accurate, consistent, and defensible results. At every stage, our experienced review managers partner with your team to define what the AI should look for, test its understanding against real documents, and verify accuracy through statistical sampling.

Step 1
Review Protocol Development

Review accuracy depends on a solid review protocol. We start with a rigorous analysis of review objectives, striving for a clear definition of responsiveness. We test the protocol against a statistically significant sample of documents, refining criteria until the AI can make confident determinations across the document population. Your team approves the final protocol before full review begins.

Step 2
Validation

Before reviewing the full collection, we validate AI accuracy against human judgment on a larger document sample. The AI provides its determination, reasoning, and certainty concerns for each document. Senior reviewers audit these determinations and calculate precision and recall metrics. Our default target is 90% recall with 80-90% precision—exceeding typical TAR standards. If accuracy falls below target, we further refine the prompt and retest.

Step 3
Linear/CAL Review

Once validation is complete, the AI reviews the full collection based on the validated protocol, providing reasoning for each determination. For smaller collections, the AI reviews every document. For larger collections, particularly those with low richness, we use our proprietary CAL algorithms to prioritize the most likely responsive documents first, substantially reducing review costs.

Step 4
Completion & Reporting

You receive comprehensive documentation: the final review protocol, AI reasoning for each determination, validation results, and a summary report documenting the entire process. Documents where the AI considers responsiveness unclear are flagged for further human review. For CAL reviews, elusion testing verifies that unreviewed documents do not contain material responsive content.

 

Review Partner in Action

AI-powered review handles even the most demanding challenges—privilege analysis, confidential redactions, and tight deadlines. Many assume these complex determinations require manual review by experienced attorneys. These case studies show how ReviewPartner delivers accurate, defensible results—often overnight.

UK Government Privilege Review
35,000 Documents

A UK government agency faced a court-ordered deadline to return privileged documents seized in a criminal raid. The collection required careful, nuanced privilege determinations—exactly the kind of analysis many assume only human reviewers can handle. We worked with our UK partner I-Lit and the client’s barristers to refine our privilege prompts through iterative testing, then processed all 35,000 documents overnight—work that would have taken weeks of barrister time.

Result: deadline met, with final sampling revealing zero privilege errors.

Corporate Contract Dispute
Confidential Third-Party Redaction

A large international corporation faced document production demands that threatened to expose confidential information belonging to third-party customers. The review required identifying and redacting customer names and logos (including images) while also analyzing surrounding text for proprietary information that could identify those customers. We developed a custom visual and text analysis system to detect both graphical logos and contextual confidential information requiring redaction. 

Result: more accurate identification than manual review, completed overnight.

Privilege. Redactions. Custom analysis. Responsive Review.
When accuracy matters and deadlines don’t move, ReviewPartner delivers. A smarter way to review.

Why Use AI for Document Review?

ReviewPartner delivers exceptional speed and accuracy through advanced AI technology. High-volume matters that would require large teams of contract reviewers can be completed by small teams of senior experts at a fraction of the cost. GenAI provides uniform, high-quality analysis across every document. Our CAL algorithm ensures the most relevant documents surface first. 

All files are maintained in locked-down AWS Virtual Private Clouds with enterprise-grade security. Three review types available—Responsive, Privilege, and Specialized—with custom prompts tailored to your case requirements.

ReviewPartner: Faster Delivery, Better Results, Lower Costs. A smarter way to review documents.
