The best e-discovery software depends on matter size and who runs the work. Relativity suits large, complex litigation. Everlaw suits collaboration-heavy teams. Logikcull (now part of Reveal) suits small and midsize matters that need self-service. Microsoft Purview fits organizations already deep in Microsoft 365. If your firm repeats the same review and drafting work, a system you own may beat renting a platform per gigabyte. This guide compares each option and explains how to choose.
TL;DR
- Large, high-stakes litigation: Relativity offers the broadest end-to-end coverage and the most deployment options.
- Collaboration and usability: Everlaw is cloud-native and built for teams that review together.
- Small matters and internal investigations: the Logikcull/Reveal line is the most self-service of the major platforms.
- Pricing is mostly quote-based and tied to data volume. Compare written quotes for the same scope, including hosting, processing, users and AI usage.
- If your firm repeats the same review and drafting workflows, an owned, custom-built system is a fourth path that keeps data and IP in your hands.

What e-discovery software actually does
E-discovery software organizes electronically stored information (ESI) so a legal team can identify, preserve, collect, process, review, analyze, produce and sometimes present evidence. Everlaw’s guide notes that no single product necessarily performs every stage. The most common supported functions are legal holds, collection, processing, early case assessment, review, analytics, redaction and production.
At the technical level, Casepoint’s explanation says the software can automate collection, indexing, virus scanning, OCR, review preparation, searching, metadata filtering, tagging, culling, redaction and production stamping. That is the work that used to take armies of contract reviewers.
Two practical consequences follow. First, you may need more than one tool, for example a collection tool feeding a review platform. Second, “best” is always relative to the stage that costs you the most.
How to choose: the criteria that matter
A useful scorecard comes from the evaluation guidance buyers and analysts publish. Digital WarRoom’s evaluation guide lists these areas to compare:
- Data-source support, metadata preservation and defensible collection.
- Processing, deduplication, threading and OCR.
- Search, review, redaction and production.
- Data residency, privacy, subprocessors, two-factor authentication and audit logs.
- Cloud versus on-premises deployment.
- Pricing, support and uptime guarantees.
The IDC MarketScape assessment from 2025 adds project management, AI and machine learning, usable search, cybersecurity, global jurisdictional coverage, cloud-to-cloud connectors, transparent pricing and broad device and application collection as critical success factors.
Weight these against your own caseload. A boutique handling a dozen small matters a year does not need the same thing as a corporate legal department running global investigations.
The main e-discovery platforms compared
G2’s 2026 review frames the market simply: Relativity for large enterprises and complex, high-stakes litigation, Everlaw for collaboration-heavy teams, Logikcull for small and midsize teams with straightforward matters, and DISCO for fast AI-driven review.
| Platform | Best fit | Deployment | Pricing model |
|---|---|---|---|
| Relativity (RelativityOne) | Large, complex litigation and investigations | Cloud, with self-hosted Relativity Server also available | Quote-based, may be set by Relativity or a partner |
| Everlaw | Collaboration-heavy teams, litigation and investigations | Cloud-only | Quote-based, primarily tied to hosted data volume |
| Logikcull / Reveal | Small to midsize matters, internal investigations | Cloud | Flat-rate and pay-as-you-go options |
| DISCO | Fast, AI-driven review | Cloud | Request a quote |
| Microsoft Purview eDiscovery | Organizations standardized on Microsoft 365 | Within Microsoft 365 | Tied to Microsoft licensing |
| Digital WarRoom | Smaller teams wanting published pricing | Private cloud | Published monthly tiers |
Relativity
Relativity describes RelativityOne as a unified AI platform spanning intake to production, including legal hold and preservation, processing, collection, review, privilege review, redaction and production. Its platform page lists ISO/IEC 27001:2022, ISO/IEC 27018, SOC 2 Type II, SOC 3 and HIPAA compliance, plus FedRAMP Moderate for the government offering.
On AI, the aiR for Review guide explains that large language models and natural-language prompts identify significant documents, explain why they matter and provide citations. Supported analyses include relevance, key documents, issues and confidential business information. In June 2026 Relativity announced that aiR Assist and custom analyses were generally available.
The independent LegalAITools comparison highlights Relativity’s extensibility, scripting and broad partner and application ecosystem. That flexibility is the draw for big teams and a lot of platform for small ones.
Everlaw
Everlaw presents itself as an AI platform for litigation and investigations covering eDiscovery, legal holds, public records requests and trial preparation. Public records requests are listed as FedRAMP-certified and GovRAMP-authorized. Its StoryBuilder feature supports case building, and the same LegalAITools comparison notes a consistent interface and direct purchasing.
On AI economics, an October 2025 release note says single-document AI Assistant actions became available at no additional cost, while batch AI actions continue to consume credits and the per-gigabyte billing structure is unchanged.
Logikcull and Reveal
PickMySoft’s 2026 review describes Reveal, built on the Logikcull platform, as the most self-service-oriented of the major platforms. It cites flat-rate and pay-as-you-go pricing for teams without dedicated e-discovery staff, and an AI Pledge that keeps customer data out of external model training.
DISCO, Purview, OpenText and Nuix
Gartner’s market listing also includes DISCO, OpenText, Nuix and Microsoft Purview eDiscovery, the last supporting discovery workflows across Microsoft 365. Purview is the logical first look if your data already lives there.
Everlaw vs. Relativity in short
This is the head-to-head readers search most. The pattern across sources is consistent:
- Deployment: Everlaw is cloud-only. Relativity runs in RelativityOne cloud or as self-hosted Relativity Server, per LegalAITools.
- Experience: Everlaw emphasizes a single, consistent interface and collaboration. Relativity emphasizes configurability and an ecosystem of partners.
- Speed claims: Everlaw says it processes up to 1 million documents per hour. That is the vendor’s own claim, so ask both vendors for throughput on your own data types.
- Pricing: both are quote-based. G2 and LegalAITools agree that data volume drives cost.
- Fit: G2 recommends Everlaw for collaboration-heavy teams and Relativity for large, complex litigation.
If your team is small, reviews together and wants to start quickly, Everlaw is the natural shortlist. If you run very large matters, need on-premises control or rely on custom workflows and partners, Relativity is.
Legal hold software: what to look for
Legal hold is often bought as a module of a larger platform. Everlaw’s guide says a good tool should let you do the following:
- Define hold scope.
- Send notices to custodians and require acknowledgments.
- Track responses with dashboards and reminders.
- Escalate non-responses.
- Provide reporting.
Treat that as a checklist when you compare vendors. Ask whether holds live in the same system as collection and review, so custodians and data sources carry through without re-entry. Everlaw’s October 2025 release also consolidated automatic legal hold reminders, which shows how this area keeps evolving.
What e-discovery software costs
Most leading platforms do not publish prices. Per LegalAITools, Everlaw and Relativity are quote-based and typically tied to data volume. Costs may also depend on seats, modules and contract term, and Relativity pricing may come from Relativity or a partner.
A useful benchmark exists from a vendor that does publish. Digital WarRoom’s private-cloud pricing lists $1,000 per month for 200 GB with $5 per GB up to 400 GB, or $2,000 per month for 500 GB with $1 per GB thereafter, including up to 50 users and reviewers. Check the page for current rates.
AI is changing the picture. According to AgenticEdiscovery.com, Relativity announced fixed-fee per-GB pricing that bundles aiR for Review and aiR for Privilege at Relativity Fest 2025, and Everlaw made core AI Assistant features free for existing subscribers. Treat that as a trend report and confirm terms in your quote.
When you request quotes, give every vendor the same scope and ask each to itemize:
- Hosting and storage per gigabyte, and how long data stays billable after a matter closes.
- Processing and any export or production fees.
- User and reviewer licensing.
- AI usage: what is included and what is metered.
- Support levels and uptime commitments.
A fourth option: own the workflow instead of renting it
The platforms above are built for litigation matters, which are bursts of data with a defined end. Many firms also face recurring document-heavy work that never closes: contract review, intake, drafting, compliance checks. Renting a per-gigabyte platform for that work means your process, and the knowledge in it, lives in someone else’s product.
That is where we work. We build custom AI-native systems for regulated industries, including legal, with compliance and security frameworks, audit trails and data sovereignty built in. The aim is that you own the complete system and the IP in it, rather than rent tools. Our approach includes private and self-hosted LLM deployment, so client data stays under your control. This does not replace a litigation review platform for a live production deadline. It suits firms that want to turn repeatable expertise into an asset.
If you are exploring this route, these guides cover the groundwork: compliance-first legal document automation, how to automate a law firm with human review and ethics controls, and an ISO 27001 checklist for AI for firms that must evidence security to clients.
Which one fits which team
| Your situation | Start with |
|---|---|
| Large enterprise, complex multi-party litigation | Relativity |
| Team reviews together, wants fast onboarding | Everlaw |
| Small firm, occasional matters, limited staff | Logikcull/Reveal or Digital WarRoom |
| Data already in Microsoft 365, in-house legal team | Microsoft Purview eDiscovery |
| Repeating review and drafting work you want to own | A custom-built system |
Whatever you shortlist, run a pilot on a closed matter with your own data and compare the output, speed and quote against the same scorecard. Ask each vendor where data is hosted, which subprocessors touch it and how AI features treat your documents.
Perspective
Most firms we meet are not short of software. They are short of ownership. A review platform is excellent at what it is built for, and we would never tell a litigator to avoid one on a deadline.
But every recurring workflow you push through a rented tool teaches that tool, and its roadmap, how your practice works. We think the better position for a firm with real domain expertise is to turn that expertise into a system it controls.
That is why we invest in firms rather than sell AI projects. We put roughly €50,000 of engineering into an established service business, on a revenue-share or equity basis. You bring the expertise and the client base, and we automate your delivery and co-build an AI-native product with you. Our team comes from regulated industries, including ISO 27001, pharma and finance, where getting AI wrong is not an option.
If you are comparing e-discovery tools because document-heavy work is eating your margin, ask a second question too: which parts of this should we own?
