Casetext and Harvey AI are two of the most discussed legal AI tools in 2026. But they serve very different needs and choosing the wrong one costs law firms time and money. This guide breaks down exactly how they compare on features, pricing, and real litigation performance, based on how legal teams are actually using both tools today.
Important update (March 2026): Casetext was acquired by Thomson Reuters in 2023 and shut down as a standalone product on April 1, 2025. Its AI features now exist within Thomson Reuters CoCounsel inside the Westlaw ecosystem. Many former Casetext users are now evaluating alternatives for litigation workflows.
Quick Verdict
- Casetext / CoCounsel (Westlaw): Best for legal research and precedent discovery
- Harvey AI: Best for enterprise legal automation
- NexLaw: Best for litigation workflow and trial preparation
Casetext vs Harvey AI: Feature Comparison (2026)

Who Is Casetext Best For in 2026?
Note: As of April 2025, Casetext no longer exists as a standalone product. The capabilities described here are now available through Thomson Reuters CoCounsel.
Casetext is best suited for mid-to-large law firms where the primary daily workflow is legal research and case law analysis. If your team spends most of its time finding relevant precedents, reviewing briefs, and checking case law citations, Casetext’s CARA AI does this well.
Where it falls short: Casetext as a standalone product has been discontinued, with its functionality moved into the Thomson Reuters CoCounsel platform
Who Is Harvey AI Best For in 2026?
Harvey AI is best suited for enterprise law firms and large in-house legal teams that need to automate a broad range of tasks like contract drafting, due diligence, compliance review, and legal research at scale.
Where it falls short: Harvey AI is expensive, with most firm-wide deployments running $50,000–$100,000+ per year. For firms that primarily litigate, paying enterprise pricing for a tool that does not support trial-stage workflow is hard to justify. Harvey AI also has a steep learning curve, it is powerful but not purpose-built for litigators.
Where Both Fall Short for Litigators
Neither Casetext nor Harvey AI was designed with the full litigation lifecycle in mind. Specifically:
- No trial preparation workflow: neither tool supports building a case strategy from first filing through closing argument
- No timeline analysis: neither can automatically extract and organise chronologies from medical records, depositions, and discovery documents
- No real-time evidence integration: neither can process new evidence mid-trial and update strategy in real time
- No deposition analysis: neither flags inconsistencies across thousands of pages of deposition transcripts
- No judge or lawyer analysis: neither provides insights on opposing counsel tendencies or judicial rulings
For law firms where litigation is the core practice, these gaps matter. A research tool is only one piece of what litigators need.
Pricing Comparison 2026
| Casetext | Harvey AI | NexLaw | |
|---|---|---|---|
| Pricing Model | Westlaw / CoCounsel subscription | Enterprise only | Flexible, accessible |
| Typical Cost | Not publicly listed | $50,000–$100,000+/year | Significantly lower |
| Best For | Research-focused teams | Large enterprise firms | Litigation-focused firms of all sizes |
| Free Trial | No | No | Yes |
Both Casetext and Harvey AI use premium or enterprise pricing structures that place them out of reach for small and mid-sized litigation firms. NexLaw was built with accessible pricing specifically for firms that litigate, from solo practitioners to regional trial firms.
What Litigation Teams Are Switching To
The shutdown of Casetext in April 2025 accelerated the search for alternatives among litigation teams that relied on it for affordable research.
Some litigation teams are moving to tools built specifically for litigation workflow, such as NexLaw. Here is why:
- CasePrep (Previously known as TrialPrep) handles the full litigation lifecycle - from case analysis and motion drafting through to trial strategy and closing arguments
- ChronoVault automatically extracts and builds case timelines from medical records, depositions, discovery documents, and evidence files, a task that takes paralegals days and ChronoVault hours
- Legal Deep Research provides citation-backed research with hallucination resistance, the same research capability as Casetext but connected to the full litigation workflow
- Real-time evidence integration means new documents uploaded during trial instantly update the case strategy, something neither Casetext nor Harvey AI can do
- Accessible pricing means regional firms and solo practitioners can access the same AI capabilities previously only available to BigLaw
NexLaw is not the right tool for every firm. If your practice is primarily transactional, contracts, M&A, compliance, Casetext or Harvey AI may serve you better. But if you litigate, NexLaw was built for exactly what you do.
