Casetext Alternatives 2026: Best Replacements After the Shutdown

If you’ve been searching for Casetext recently, you may have discovered that the platform is no longer available as a standalone product. On April 1, 2025, Casetext officially shut down its independent legal AI research platform.

This guide explains what happened, where Casetext’s technology went, and — most importantly — what the best alternatives are for the attorneys and firms who depended on it.

What Happened to Casetext?

Casetext, founded in 2013, was one of the early pioneers in AI-powered legal research. Its CoCounsel product — launched in 2023 as one of the first GPT-4-based legal AI tools — gained significant traction and was widely regarded as one of the most capable legal AI products available to smaller firms.

In August 2023, Thomson Reuters acquired Casetext for approximately $650 million. After the acquisition, Thomson Reuters integrated Casetext’s technology into its flagship Westlaw platform.

As of April 1, 2025:

Casetext.com has shut down as an independent platform
CoCounsel is now bundled with Westlaw Precision — the new name for Thomson Reuters’ AI-enhanced legal research product
Existing Casetext subscribers were migrated to Westlaw or offered alternative terms

If You Want CoCounsel, You Now Need Westlaw Precision

The simplest “alternative” to Casetext is not an alternative at all — it’s Westlaw Precision, which now includes CoCounsel functionality.

Westlaw Precision with CoCounsel

What it includes:

Full Westlaw legal research database (40+ years of case law, statutes, regulations)
CoCounsel AI for research drafting, document analysis, and case summarization
AI Jurisdictional Surveys
Claims Explorer for patent and IP matters
Brief Analyzer (check citations and arguments)

The trade-off: Westlaw Precision is significantly more expensive than Casetext was as a standalone. For many small firms and solo practitioners who used Casetext specifically because it was more affordable than Westlaw, this migration is painful from a cost perspective.

Pricing: Westlaw Precision is not transparently priced; contracts are negotiated. Small firm pricing is typically in the $300–$600/month range per seat depending on practice area and coverage selected.

If Westlaw pricing is prohibitive, the alternatives below are worth evaluating.

Best Casetext Alternatives for Small Firms and Solo Practitioners

1. Lexis+ with Protégé (Formerly Lexis+ AI)

Best for: Firms seeking a full-service alternative to Westlaw Precision at a comparable price point

Pricing: Included in Lexis+ subscriptions; pricing varies

In February 2026, LexisNexis rebranded its Lexis+ AI product to Lexis+ with Protégé — an end-to-end AI workflow platform built into the Lexis+ research environment.

What Lexis+ with Protégé offers:

AI-powered legal research with citation grounding (responses tied to verifiable sources)
Document drafting assistance (memos, briefs, correspondence)
Workflow automation for legal research tasks
Access to Lexis’s core database: case law, statutes, regulations, secondary sources

How it compares to Casetext/CoCounsel: Lexis+ with Protégé is a comparable product to Westlaw Precision + CoCounsel — both are AI-enhanced research platforms built on large proprietary legal databases. Attorneys who were Casetext-only users may find Lexis+ more accessible than transitioning to Westlaw, particularly if their firm has existing Lexis contracts.

The key limitation is the same as Westlaw: the cost is enterprise-tier relative to what Casetext charged as a standalone.

2. Paxton AI — Best Budget-Friendly Alternative

Best for: Solo practitioners and small firms who want AI legal research without Westlaw/Lexis pricing

Pricing: Reported at significantly lower price points than Westlaw ($50–$150/month range)

Paxton AI is a purpose-built legal AI platform that raised a $22M Series A in 2025. It offers legal research, document drafting, and contract analysis — covering the core use cases that Casetext handled — at pricing designed for smaller firms.

Paxton’s research is grounded in legal databases but is not as deep as Westlaw’s or LexisNexis’s proprietary data. For common research tasks (case law summaries, statutory analysis, brief drafting), Paxton performs well. For specialized or highly complex research, the depth gap versus Westlaw may matter.

Why Paxton is worth considering: If price was a core reason you chose Casetext over Westlaw, Paxton fills that niche more directly than migrating to Westlaw Precision.

3. Harvey AI — Best for Large Firms (Not a Budget Option)

Harvey has absorbed much of the enterprise-tier interest that Casetext occupied for large firms. But Harvey’s pricing — reported at $300,000+ annual minimums — places it firmly in the AmLaw 100 segment.

If you’re a large firm with the budget, Harvey may be the right move. For everyone else, Harvey is not a practical Casetext replacement.

4. Legora — Emerging Option for Research-Intensive Practices

Legora, valued at $5.55 billion as of March 2026, has been acquiring research platforms (including the recent acquisition of Qura) and positioning itself as an AI-native legal research tool. Its target is law firms that need deep research support.

Legora is relatively new to the US market and best suited for firms willing to adopt an emerging platform. Watch this space.

5. Practice Management + AI Integration (Clio Duo)

For attorneys who used Casetext primarily for quick research summaries — not deep research — integrating AI into a practice management platform like Clio may cover many of the same use cases at a lower total cost.

Clio Duo (included in Clio Advanced and Complete plans at $99–$139/month per user) can:

Summarize documents and matter information
Draft correspondence and internal memos
Answer questions about your matter data

It doesn’t replace deep legal research, but for routine drafting and summarization tasks, it significantly reduces the daily research burden without a dedicated research subscription.

Which Alternative Is Right for You?

Your Situation	Best Option
You want CoCounsel specifically	Westlaw Precision (it’s now built in)
You need full-service research at Westlaw’s level	Lexis+ with Protégé (comparable platform)
You need AI research at a smaller firm price	Paxton AI
You primarily used Casetext for drafting/summarizing	Clio Duo (if you use Clio)
Large firm with budget	Harvey AI or Westlaw Precision
Willing to try emerging tools	Legora

The Bottom Line

Casetext’s shutdown is a genuine loss for small firm legal AI — it was one of the few tools that offered serious AI research capabilities at an accessible price point.

The migration path Thomson Reuters wants you to take (Westlaw Precision) is the most technically complete option, but the price increase may be substantial. Paxton AI is the most direct budget-friendly alternative, while Lexis+ with Protégé is the best option for attorneys who need a full-service alternative at a comparable tier.

For most small firms, the practical advice is: evaluate Paxton AI first for fit, then compare Westlaw Precision and Lexis+ pricing before committing to either enterprise platform.

What to Evaluate When Choosing a Casetext Alternative

Before committing to a replacement research platform, evaluate each option against the specific ways you used Casetext. Casetext users came from very different needs — some were primarily using it for cost-effective case law research, others for CoCounsel’s AI drafting capabilities, and others for brief analysis.

If you primarily used Casetext for case law research on a budget: Paxton AI is the most direct replacement — it covers federal and state case law research at a significantly lower price than Westlaw. You should also evaluate whether Fastcase (included free with many state bar memberships) covers your jurisdiction adequately before paying for anything.

If you primarily used CoCounsel for AI-assisted drafting and document analysis: The capabilities are now in Westlaw Precision, which means you’d need to evaluate whether the price increase is justified. For attorneys who used CoCounsel primarily for document review and drafting support — not deep research — a contract-focused tool like Spellbook may cover those use cases at a lower cost than a full Westlaw subscription.

If you used Casetext primarily for brief analysis and citation checking: Westlaw Precision includes Brief Analyzer, which performs similar functions. Lexis+ with Protégé also includes citation and argument analysis tools.

Frequently Asked Questions

Is Fastcase a viable Casetext alternative? Fastcase is a legal research database included for free with most state bar memberships. It provides solid case law coverage but lacks the AI-powered drafting and analysis capabilities that CoCounsel offered. It’s a reasonable option for basic research at zero additional cost, but not a complete Casetext replacement for attorneys who relied on the AI features.

Did Thomson Reuters honor Casetext’s pricing commitments after acquisition? Attorneys migrated from Casetext to Westlaw Precision generally report that the migration resulted in significantly higher costs compared to their former Casetext subscriptions. Thomson Reuters offered transition pricing to some former Casetext customers, but many reported the final Westlaw pricing was substantially above what they had paid for Casetext as a standalone.

How accurate is Paxton AI compared to Westlaw for legal research? Paxton AI publishes a 94% accuracy benchmark on legal research tasks. Westlaw and LexisNexis ground AI responses in their verified legal databases, which reduces hallucination risk below that of any standalone AI tool. For research that will appear in court filings, Westlaw or Lexis remains the safer choice from an accuracy standpoint.

Is there a free Casetext alternative? Beyond Fastcase (free with bar membership), several AI research tools offer free trials (Paxton AI offers 7 days; Lexis+ offers trial access). There is no free permanent alternative that replicates Casetext’s AI research capabilities.

What should I do before canceling my Casetext/Westlaw transition contract? Make sure to export any saved research, folders, and work product from your Westlaw account before cancellation. Westlaw’s export tools allow downloading research history and documents. Review your contract terms carefully — Westlaw contracts typically have notice requirements and minimum commitment periods.

Can I use multiple research tools simultaneously? Yes, many small firm attorneys use Paxton AI for routine research while maintaining a limited Westlaw or Lexis subscription for complex matters where database accuracy is paramount. Some state bar Fastcase memberships can serve as the fallback research option at no additional cost.
