Some corporate counsel are re-evaluating Casetext post-acquisition due to pricing changes and Thomson Reuters lock-in. This guide reviews CoCounsel 2.0, Harvey AI, Leya, Robin AI, and Legora as alternatives with a comparison table.
The general counsel of a mid-size pharmaceutical company had been a Casetext advocate since 2022. She had championed its adoption for her eight-person in-house team, built workflows around its research and drafting capabilities, and recommended it to peer GCs at industry conferences. Then her Thomson Reuters contract came up for renewal in early 2026, and the pricing conversation changed. The bundled CoCounsel-Westlaw Precision package represented a substantial increase over her prior arrangement, with feature access tied to a Westlaw subscription that her team used for perhaps 20% of what it provided.
Her question — one that an increasing number of corporate counsel are asking — was whether there was a better-fit alternative for an in-house team that needed AI-assisted research and drafting, without paying for a full Westlaw subscription she did not fully utilize. This article provides a structured evaluation of the five most viable alternatives for corporate counsel evaluating a Casetext replacement.
The corporate counsel market for AI tools has evolved significantly since Thomson Reuters acquired Casetext and retired the standalone Casetext platform on April 1, 2025. The original Casetext value proposition — affordable, attorney-friendly AI research at a price point accessible to in-house teams — has been repositioned upmarket. CoCounsel is now sold primarily as part of enterprise Westlaw bundles rather than as a standalone product that in-house teams can evaluate and price independently.
This repositioning reflects Thomson Reuters' business logic: Westlaw Precision is the company's core revenue product, and CoCounsel's value is partly as a retention mechanism for Westlaw subscribers. But it creates a mismatch for in-house teams whose research needs do not justify Westlaw's depth — teams that primarily need AI drafting assistance, contract review, and regulatory research rather than comprehensive legal database access.
The market has responded with a range of alternatives that target exactly this gap. Harvey AI expanded its in-house legal product substantially in 2025, with features specifically designed for corporate legal departments. European AI legal tools — particularly Leya, Legora, and Robin AI — have gained traction with multinational in-house teams that need EU data residency alongside strong legal AI capability. Luminance, which had been primarily known for due diligence, has expanded into research and drafting use cases.
The replacement decision is not purely about cost. It involves assessing which tool fits your team's actual workflow, what integration requirements exist with your existing CLM or matter management platform, and whether EU data residency is a requirement rather than a preference.
For in-house teams that value Westlaw integration and are otherwise satisfied with Thomson Reuters' ecosystem, CoCounsel 2.0 is the natural path. The 2.0 version addresses several limitations of the original: memo drafting quality has improved, contract review handles larger document sets more reliably, and the Westlaw Precision integration provides real-time citation verification that standalone AI tools cannot replicate.
The honest assessment: if your team's re-evaluation is primarily about pricing rather than product limitations, CoCounsel 2.0 is worth negotiating for rather than replacing. Thomson Reuters has pricing flexibility for in-house teams who can demonstrate they are considering alternatives. A well-prepared alternatives analysis — which this article supports — is a valuable negotiation tool even if you ultimately stay with CoCounsel.
If your re-evaluation reflects genuine product limitations — particularly for teams doing heavy contract review, regulatory research, or EU-law work — alternatives may deliver better-fit capability at comparable or lower cost.
Harvey AI has become the leading alternative to CoCounsel for corporate counsel doing sophisticated legal analysis. Its strengths map directly to common in-house use cases: M&A support (due diligence, representation and warranty analysis, regulatory clearance research), regulatory research (analyzing new rules' applicability to business operations), employment matters (policy analysis, separation agreement drafting), and commercial contract review.
Harvey's architecture is more flexible than CoCounsel's: it integrates with multiple research databases and document management systems rather than being optimized for a single database. This flexibility is valuable for in-house teams whose research needs span multiple areas of law without a single database serving all needs optimally.
Pricing is comparable to CoCounsel's enterprise tier, but Harvey is not bundled with a research database subscription — the tool cost is the tool cost. For teams that do not need Westlaw's depth, this unbundled pricing may represent meaningful savings.
Leya is a Swedish AI legal research and drafting tool built specifically for the European legal market. Its core differentiators are EU data residency (data processed on EU infrastructure by default), research coverage of EU legal systems including Swedish, German, French, and Dutch law alongside EU-level materials, and a user experience designed for civil law jurisdictions as well as common law.
For multinational in-house teams with significant EU operations, Leya's jurisdiction coverage is a genuine capability advantage over U.S.-centric tools. A U.S.-headquartered company with European operations might use Harvey AI for U.S. matters and Leya for European legal research and contract analysis — a two-tool approach that addresses the jurisdiction coverage gap.
Leya's pricing is competitive with CoCounsel and Harvey at comparable team sizes, with EU data residency included rather than as a premium tier option.
Robin AI specializes in contract review, negotiation support, and redlining — workflows that drive a large portion of in-house legal team workload. Its AI is trained specifically on commercial contract language and can apply playbook logic (your organization's preferred positions on specific clause types) more systematically than general-purpose AI tools.
For in-house teams whose primary AI need is contract work — NDA processing, commercial agreement review, vendor contract management — Robin AI delivers more specialized capability than CoCounsel or Harvey. Its integration with contract management workflows and its redlining capabilities are stronger than general research and drafting tools.
Robin AI is UK-based with EU data residency options, making it suitable for European teams or multinational organizations with EU GDPR requirements.
Legora is a Stockholm-based AI legal research platform that competes with Leya for the European in-house market. Its strength is depth of research coverage across Nordic and European jurisdictions, with strong performance on regulatory research and case law analysis in Swedish, Norwegian, and EU law. For in-house teams at companies with Nordic operations, Legora provides jurisdiction-specific research depth that general platforms cannot match.
Legora's EU data residency, Article 28 DPA, and privacy compliance posture are strong — a meaningful consideration for European legal teams evaluating AI tools under GDPR constraints.
Structured Replacement Evaluation Process
A GC at a European-headquartered manufacturing company with U.S. operations runs a 60-day replacement evaluation. She identifies her team's three primary AI use cases: contract review (70% of AI use), regulatory research (20%), and occasional research memo drafting (10%). She pilots Harvey AI and Leya simultaneously, assigning contract review tasks to both and regulatory research to Leya specifically.
After 60 days: Harvey AI produces superior contract review output for U.S. commercial agreements; Leya produces superior output for EU regulatory research and German-law contracts. The conclusion: a two-tool deployment at combined cost lower than the CoCounsel/Westlaw bundle she was leaving. The EU data residency advantage of Leya resolved a pending compliance question her DPO had flagged.

Q: Is it worth staying with CoCounsel and negotiating pricing, rather than migrating to an alternative?
A: If your team's primary workflows are research and drafting, and you use Westlaw regularly, negotiating is worth attempting before migrating. Use this alternatives analysis as leverage. If your primary use case is contract review or EU law, alternatives may deliver better-fit capability regardless of pricing.
Q: How difficult is it to migrate workflows from CoCounsel to Harvey AI?
A: Workflow migration is primarily a prompt library and training exercise — there is no data to migrate since AI tools do not store client work product (check your DPA to confirm). Budget 30-45 days for team retraining and prompt template rebuilding. The main migration cost is productivity dip during the transition period.
Q: Does Leya cover common law jurisdictions (UK, Ireland) or only civil law European countries?
A: Leya has expanded its coverage to include UK and Irish law alongside continental EU jurisdictions. For multinationals with UK operations, Leya provides usable coverage, though depth may not match UK-specific tools like Luminance or Robin AI for complex UK matters.
Q: How do these alternatives compare on hallucination risk for legal citations?
A: All major tools have citation verification mechanisms, but none provides the live KeyCite integration that CoCounsel has through Westlaw Precision. For tools without live database connections, citation verification through a separate research platform remains necessary before relying on AI-generated citations in documents shared externally. See our glossary on AI hallucination.
Q: What contract review features should we require before selecting a CoCounsel replacement?
A: Minimum requirements: ability to apply your organization's contract playbook, extraction of key terms to structured output, identification of missing clauses, redline generation, and integration with your CLM platform. Test each against 10 real contracts from your organization before finalizing selection.
