Choosing the right e-discovery platform can feel like drinking from a firehose—so much data, so many vendors, and real legal risk if you pick the wrong fit. This article reviews the top 5 SaaS e-discovery tools, compares features, cost signals, and real-world use cases so you can make a faster, smarter decision. If you want a quick primer on the concept, see the background on electronic discovery.
How I evaluated these platforms
I looked at scalability, search and analytics, document review ergonomics, chain-of-custody/compliance features, pricing signals, and cloud-native strengths. I also considered where teams often struggle: data privacy, cross-jurisdiction preservation, and efficient review workflows.

1) RelativityOne — best for enterprise scale
RelativityOne is the market stalwart I often see used for massive matters. If you’ve got petabytes of data, complex analytics needs, or deep integration requirements, RelativityOne scales and integrates with many third-party tools.
Why pick it: Best-in-class analytics, extensible platform, and robust security controls. It’s not cheap, but for high-risk, high-volume litigation it pays off.
Real-world example
A corporate litigation team I advised used RelativityOne to centralize discovery across five global offices and reduce review time via clustering and concept search.
2) Everlaw — best for collaborative review
Everlaw mixes speed with a clean UX. From what I’ve seen, legal teams love the timeline visualization and collaborative review features that let multiple reviewers work seamlessly.
Why pick it: Intuitive UI, powerful search, strong redaction and production tools. Great for teams that want less admin overhead.
3) Exterro — best for legal ops & compliance
Exterro aims to cover the full lifecycle: hold notifications, preservation, collection, review, and audits. If your org needs e-discovery tightly integrated with legal operations and privacy workflows, Exterro stands out.
Why pick it: Workflow orchestration and compliance-focused modules. It’s practical for internal investigations and data subject-request coordination.
4) Logikcull — best for speed and small teams
Logikcull is refreshingly simple. Drag, drop, process, and review. For small firms or corporate legal teams who need fast turnarounds without steep admin or setup costs, Logikcull is ideal.
Why pick it: Fast ingest, transparent pricing options (including pay-as-you-go), and minimal setup time.
5) DISCO — best for law firms focused on speed and AI
DISCO emphasizes automation and clean workflows. It’s built by lawyers and often praised for speedy review and strong predictive tools.
Why pick it: Automated workflows, strong customer support for law firms, and built-in analytics that reduce manual triage.
How to choose — a short decision checklist
- Volume & complexity: Enterprise matters → RelativityOne; modest volumes → Logikcull or Everlaw.
- Budget: If cost is a constraint, start with Logikcull or request modular pricing from Exterro.
- Legal ops integration: Choose Exterro for integrated workflows and compliance tracking.
- Speed of setup: Need results in days? Prioritize Logikcull or Everlaw.
- Advanced analytics: RelativityOne and DISCO lead on ML/predictive coding.
Security, privacy and regulatory flags to watch
Any SaaS e-discovery tool must handle chain-of-custody, encryption-at-rest/in-transit, and regional data residency if you operate across jurisdictions. Check SOC 2, ISO certifications, and contractual SLAs. For regulatory context on electronic discovery processes, refer to the procedural background on Wikipedia or specific jurisdictional guidelines.
Pricing signals and procurement tips
Vendors often price by a mix of data volume, active users, features, and retention. Ask for:
- Transparent egress fees
- Sample contracts and data-breach clauses
- A pilot or proof-of-concept for realistic datasets
Sample use cases
- Internal investigation with fast timelines: Logikcull or Everlaw
- Mass litigation with terabytes: RelativityOne
- Privacy and DSAR coordination: Exterro
- Firm-wide review efficiency: DISCO
Tool roundup — my quick recommendations
- Best enterprise: RelativityOne
- Best mid-market / collaboration: Everlaw
- Best legal ops: Exterro
- Best small-team fast-start: Logikcull
- Best for predictive review: DISCO
Next steps — a practical pilot plan
Pick two finalists, run a 2–4 week pilot with a true sample dataset, measure review speed, false-positive/negative rates from search, and reviewer satisfaction. That simple test usually reveals fit faster than slides and demos.
