How AI in Review Accelerates Case Strategy and Reduces eDiscovery Costs Across All Case Sizes
In today’s litigation and investigation landscape, data volumes and communication channels continue to multiply. From emails and chat platforms to mobile data and collaboration tools, legal teams face an overwhelming challenge: identifying what matters most, as early as possible. The sooner counsel can assess case merit and key issues, the better equipped they are to shape strategy, evaluate risk, and control costs.
That’s where artificial intelligence (AI) in investigations and eDiscovery review comes in.
Early Case Assessment: Finding the Signal in the Noise
Traditional early case assessment (ECA) often required broad culling strategies, search term testing, and manual review of sample sets. While useful, those methods can be time-consuming and costly, especially when data sets are massive.
AI-driven review tools like generative AI-powered analysis, allow teams to:
- Quickly surface key evidence: AI learns from reviewer input, identifying documents most likely to be relevant far faster than linear review.
- Spot patterns and themes: Similar to Technology Assisted Review (TAR) and other workflows, AI can cluster related documents, highlight communication spikes, and uncover custodians or topics of interest that may not appear in keyword lists. AI is now the fastest way to organize and find patterns in your data, much more efficiently and effectively than other methods.
- Assess case merit earlier: With faster access to the “hot” documents, legal teams can make informed decisions on settlement, litigation strategy, or resource allocation at the outset.
Cutting Downstream Review Costs
The benefits of AI extend well beyond ECA. By embedding AI throughout the review workflow, organizations can dramatically reduce downstream costs, which often make up the largest portion of discovery spend.
- Smarter prioritization: AI identifies relevant material faster, ensuring that reviewers spend time where it matters most and can categorize data by issues or topics.
- Consistent coding: AI maintains coding consistency across large reviewer teams, across every issue, by suggesting categorizations based on your specific instruction. It applies that instruction, consistently across every document, every time.
- Eliminating redundancies: AI can detect near-duplicates, email threading, and conversation reconstruction, allowing reviewers to avoid re-reading similar documents.
- Reducing review volumes: Accurately identifying irrelevant material and excluding those up-front results in fewer documents remaining in the costly final stages of review. Lower volumes equal lower costs.
Building Confidence with Defensibility
One of the biggest questions around AI in eDiscovery has always been defensibility. Many of the protocols for AI review are identical to those for TAR related projects and are already familiar to those in litigation. Documented protocols, validation sampling, and transparent reporting ensure that AI-powered review stands up to scrutiny while driving efficiency. Additional features like document summarization and relevancy explanation help confirm each individual coding classification.
A Smarter Path Forward
For legal teams balancing speed, accuracy, and cost, AI is no longer optional it’s becoming essential for cases of ALL sizes. Leveraging AI during review not only accelerates the path to critical evidence and early case insight, but also dramatically reduces the burden of downstream review.
The result?
- Faster decisions on case strategy.
- Lower overall discovery costs.
- Greater confidence in outcomes.
In an era of ever-expanding data, those who integrate AI into their review workflows will be best positioned to gain the competitive advantage in litigation and investigations and isn’t limited to large cases as the economics of the technology and services align with cases of all sizes.
