To fully grasp the transformative power of GenAI in ediscovery, a comprehensive understanding of its underlying mechanisms, advantages, disadvantages, and the financial considerations involved is essential for legal professionals navigating this evolving technological frontier.
GenAI in Ediscovery
GenAI distinguishes itself from traditional machine learning by its ability to create new content and information, rather than just classifying or analyzing existing data. In ediscovery, this translates into capabilities that can significantly streamline workflows and reduce manual effort.
GenAI can accelerate the document review process by producing thorough summaries of legal documents, making it easier for lawyers to quickly grasp key information from large volumes of data. This capability allows legal professionals to identify key data points and relevant information more efficiently, enabling them to focus on the most critical aspects of a case.
Beyond summarization, AI tools can also assist with drafting various legal documents, such as statements of facts or deposition summaries, often complete with citations to supporting documents. It can even help with creating case narratives, providing a concise overview of facts and issues for trial preparation.
Despite GenAI’s potential to help transform the legal industry, many organizations are still hesitant to fully embrace it because they view it as cost-prohibitive. There’s still an open question about how much GenAI costs, and how cost-effective it might be. While these are valid concerns, teams that wait to adopt GenAI run the risk of falling behind the competition.
How Much Can You Expect to Pay for GenAI?
Legal technology providers offering generative AI solutions often employ various pricing models to accommodate diverse client needs and usage patterns. Understanding these models is key to predicting and managing ediscovery costs.
Usage-Based Models
This is a pay-as-you-go approach where costs are directly tied to the actual consumption of AI services. This could be based on the number of documents summarized, the volume of data processed by AI features (e.g., per GB), the number of AI-generated drafts, or even the duration of AI processing time. This model is flexible for varying workloads but requires careful monitoring to prevent unexpected costs.
As a subset of the usage-based model, there’s also a credit-based model in which clients purchase "credits" that are consumed as they use specific GenAI features. Credits are charged for each task that’s carried out, with different tasks requiring different numbers of credits. For example, generating a document summary might cost 20 credits, while coding a set of documents might cost 50 credits. This model offers predictability as clients can pre-purchase credits based on anticipated usage.
Hybrid Models
Many providers combine elements of the above. For instance, a base subscription might include core ediscovery features and some basic AI usage, with additional, more advanced GenAI functionalities available through a credit or usage-based add-on. This allows for flexibility and scalability.
Tiered or Subscription Models
Some providers offer different subscription tiers, each providing access to a specific set of GenAI features and a certain level of usage allowance for a fixed monthly or annual fee. Higher tiers typically include more advanced features or higher usage limits. Costs increase only if a client moves to a higher tier or exceeds included allowances, potentially incurring overage fees.
A subset of the tiered model is the per-user licensing model. While less common for the AI itself, some platforms might combine AI feature access with traditional per-user licensing for the overall platform. This means a base cost per user, with AI usage potentially layered on top via a credit or usage-based system.
Advantages of GenAI Costs in Ediscovery
The integration of GenAI into ediscovery offers several compelling advantages and use cases that directly translate into cost savings and improved financial efficiency.
Accelerated Document Review and Reduced Labor Costs
GenAI can significantly speed up the document review process by automatically summarizing documents and highlighting key information. This drastically reduces the time legal professionals spend manually sifting through large volumes of ESI, leading to substantial reductions in labor costs associated with extensive human review.
Lower Litigation Costs
By automating time-consuming manual tasks, GenAI can lead to significant overall cost savings for both law firms and clients. Lowering litigation costs, particularly during the ediscovery phase, can also increase access for smaller firms that might otherwise be priced out due to high expenses during discovery.
Efficient Data Handling and Processing
GenAI's ability to process and analyze a wider array of data types, including complex and unconventional formats like videos, audio files, and various messaging platforms, can prevent the need for specialized, often costly, tools or manual workarounds for different data sources. This comprehensive approach can streamline data processing costs.

GenAI can automate various administrative tasks associated with ediscovery, such as generating privilege logs or organizing documents. This automation reduces the administrative overhead and associated labor costs that typically accompany these processes.
Optimized Resource Allocation
By handling routine and high-volume tasks, GenAI allows legal professionals to focus on higher-value activities that require human judgment and strategic thinking. This optimizes the allocation of expensive legal talent, ensuring resources are deployed where they can have the most impact, rather than on tedious review tasks.
Pricing Factors for GenAI
The cost of GenAI for ediscovery services is not a one-size-fits-all figure, as it depends on a multitude of factors, similar to traditional ediscovery pricing models. However, it's important to understand that while the initial investment might seem significant, the long-term cost savings through increased efficiency can be substantial.
Generally, GenAI ediscovery costs are influenced by the volume and complexity of the data, the specific features and functionalities required, and the service provider's pricing model. Unlike traditional ediscovery, where costs are heavily tied to manual labor hours for review, GenAI can significantly reduce these per-hour review costs by automating large portions of the process.
Data Volume and Type
The sheer amount of data (in gigabytes or terabytes) to be processed is a primary cost driver. The complexity of data types (e.g. structured vs. unstructured, common vs. esoteric file formats, multimedia) can also impact pricing, as more complex data may require more sophisticated processing and AI models.
Features and Functionality
The range of GenAI features utilized will affect the cost. Basic functionalities like document summarization might be less expensive than advanced capabilities such as automated drafting, complex query generation, or multi-language processing. Providers may offer different tiers of service based on the depth of AI functionality.
Hosting and Storage
Like traditional ediscovery, the cost of securely hosting and storing ESI over the lifecycle of a case is a significant factor. Cloud-based solutions may offer scalable storage and the ability to manage data in-house but also come with associated hosting fees. Generally, on-prem ediscovery software is less compatible with GenAI systems than cloud-based, so there are also limiting factors in that regard.
User Licenses
Many GenAI ediscovery platforms operate on a per-user license model, where the cost increases with the number of legal professionals accessing and utilizing the system.
This can have both positive and negative impacts depending on how the GenAI system is utilized. For example, if a large majority of your organization is constantly using GenAI tools for a variety of tasks, the user license model might be more cost-effective.
However, if your organization is leveraging GenAI in a specialized way for specific use cases, the user license arrangement might not be the most financially efficient.
Training and Support
The level of training and ongoing support provided by the vendor can also influence pricing. Comprehensive training to ensure effective adoption and readily available technical support are crucial for maximizing the value of the AI investment.
Cost Recovery
Cost recovery is an important mechanism for understanding how legal organizations can help cover the expenses associated with their GenAI tools.
For example, law firms have the ability to pass on the expenses associated with advanced GenAI tools to clients depending on things like retainer agreements, fee structures, and the specific jurisdiction's rules regarding billable technology. Demonstrating how GenAI implementation leads to a more efficient and ultimately more affordable discovery process than traditional methods despite the specialized technology fees is crucial to reconciling the costs of these tools with clients.
For in-house legal departments, cost recovery often translates to demonstrating a positive return on investment (ROI) to their internal stakeholders. This involves tracking the savings generated by GenAI in terms of reduced external vendor spend, fewer hours dedicated by internal legal teams to manual tasks, and faster resolution of matters.
