How We Chose the Best Electronic Discovery Software

Electronic discovery software, also called eDiscovery software, provides the tools legal professionals need to review, process, tag, and produce electronic documents as part of the discovery materials required for investigations or lawsuits. Electronic documents include any electronically stored information, including emails and all types of computer files. Law firms will find many electric discovery software companies that all boast the latest features and services. We evaluated these companies based on some of the most important features, including discovery features, extraction features, and integrations.

Discovery Features

Discovery features, such as keyword search and topic clustering, allow users to locate and organize information. Document indexing associates records with keywords, which makes it more efficient to search for specific documents using keyword search features during the review process. Topic clustering sorts documents based on related topics, helping users see common patterns and themes, which is especially helpful for litigators. We evaluated companies on the effectiveness of their discovery features.

Extraction Features

Before documents can be organized and indexed, eDiscovery software must have the features for extracting full-text and metadata. Full-text extraction features scan files and run optical character recognition so that files can be indexed and searched. Metadata extraction withdraws and stores the metadata of electronically stored information, including date, author, and topic. We focused on electronic discovery software with robust extraction features.


Integrations have become an increasingly important part of electronic discovery software because eDiscovery is a dynamic process that must be able to leverage other technologies. Ideally, the software will have prebuilt integrations for case management software, human resources (HR) systems, and other enterprise data sources and information technology (IT) investments. We evaluated electronic discovery software based on technology integrations that improve the exchange of up-to-date information and reduce the risk of human errors.

What Is Electronic Discovery Software?

eDiscovery software provides the tools legal professionals need to process, review, and tag all types of electronic documents for use in an investigation or a lawsuit. Previously, parties in a dispute exchanged numerous boxes of paper documents, but these have largely been replaced by computer-generated and electronically stored content that takes less storage space and less time to compile. Electronically stored information can include emails, cellphone data, social media posts, chat sessions, instant messages, word processing documents, digital audio and/or video recordings, GPS data, and any other digital records people produce every day.

Electronic discovery is a primary way of uncovering the facts in a dispute, so having the right eDiscovery software is vital to unearth valuable information that might not otherwise be found. Once data has been loaded into an eDiscovery platform, legal professionals can review this data by creating searches to find specific documents, sort details using metadata fields, and tag files appropriately. Users can then review prepared data and produce the documents needed for their legal proceedings. eDiscovery software automates the entire discovery process, saving time and money. Choosing a cloud-based version provides further flexibility and collaboration with anytime, anywhere access.

Benefits of Electronic Discovery Software

Reviewing documents in complex legal cases is extremely time-consuming, which translates to high costs. Electronic discovery software can automate this process, making it much more efficient. Software programs can go through reams of data much more quickly than humans. This can be especially important if a legal team is pressed for time to create a production. Some of the many other benefits of electronic discovery software include:

  • Saving time and money: Probably the biggest benefit is the amount of time saved by eliminating the need to scan every electronically stored piece of information physically. Less time spent searching through data translates to less money spent paying someone to search.
  • Advanced search: Software has the technology to enable advanced search functions using robust metadata and tagging, which makes it easier for users to focus on specific parameters and keywords.
  • Identifying gaps: eDiscovery software identifies what’s missing from a production by searching for gaps, especially gaps between dates where there should be documents.
  • Technology-assisted review: Utilizing AI to analyze content allows documents to be ranked or grouped based on the likelihood that the information is relevant to the case, making the review more focused.

Must-have Features of Electronic Discovery Software

Identifying, tagging, and sharing key data from electronically stored documents ensures both parties in a lawsuit or another legal battle have access to the same information. To be effective, electronic discovery software must have certain features that allow extraction of data that can then be organized in a meaningful way. Some must-have features of electronic discovery software include:

  • Document tracking: Shows users each document’s progress throughout the eDiscovery process, including who viewed which documents and when
  • Full-text extraction: Scans files and runs optical character recognition so that all files can be indexed and searched
  • Metadata extraction: Extracts and stores all the metadata attached to electronically store information (ESI), including the author’s name, date the ESI was created, and the topic of a given document
  • Topic clustering: Groups information based on related topics so users can review the overviews provided and search for common patterns or themes running through the electronic documents
  • Document indexing: Associates records with keywords to provide more efficient search and review processes
  • Optical character recognition: OCR scans text contained within an image and converts it into text that can be searched
  • Comments/notes: Allows users to write comments on documents and underline and highlight text

The Cost of Electronic Discovery Software

When electronic discovery software was in its infancy, it wasn’t uncommon for vendors to charge exorbitant rates, including numerous extra fees to cover certain tasks. As competition increased, costs for these software systems began to drop. However, many companies still charge extra fees for some features. When comparing costs of eDiscovery software, law firms must make sure the costs are proportional to the average value of the cases they typically handle to meet the current requirements of the Federal Rules of Civil Procedure (FRCP). A hosted eDiscovery system with a subscription-based fee structure should meet FRCP regulations while still offering value to the user.

Most eDiscovery software providers use a per-user, per-month, pricing method. However, many also charge extra for uploaded materials, which is usually a per-gigabyte fee. This additional fee can add up, especially for large firms or legal professionals who consistently handle complex cases with lots of data to upload. Of the companies that made our list, many of them didn’t provide public pricing information for comparison. Price ranges of those providing this information are $5 to $350 per user, per month, with monthly hosting or uploading fees between $1 and $15 per gigabyte.
