Citation Safe vs. Casetext / CoCounsel
By Andy Gaber
Casetext, once a favorite AI research tool for solo and small-firm lawyers, was acquired by Thomson Reuters for $650 million in 2023 and shut down as a standalone product on April 1, 2025. Its technical successor, CoCounsel Legal, now lives inside Thomson Reuters' Westlaw Advantage ecosystem at a materially higher price point. This comparison is really about accessibility for the exact buyer Casetext used to serve well.
| Comparison | Citation Safe | Casetext / CoCounsel |
|---|---|---|
| Product status | Active, independently operated | Casetext discontinued Apr 2025; folded into CoCounsel Legal / Westlaw Advantage |
| Target buyer | Solo practitioners and small firms | Firms already on, or upgrading to, Westlaw Advantage |
| Reported per-seat cost vs. original Casetext | N/A — self-serve $12–$79/mo tiers | Reported at roughly 3x original Casetext per-seat pricing |
| Standalone availability without a Westlaw contract | Yes, always self-serve | Bundled with the broader Westlaw ecosystem |
| Core function | Citation verification specifically | Full AI legal research and drafting assistant |
What happened to Casetext
Casetext built genuine goodwill among solo and small-firm lawyers as an accessible, well-priced alternative to Westlaw and Lexis. Thomson Reuters' 2023 acquisition and subsequent shutdown of the standalone product in April 2025 removed that specific option from the market. Its capabilities live on inside CoCounsel Legal, but reporting indicates the successor is priced meaningfully higher — roughly three times the original Casetext's per-seat cost — and is now positioned within the broader Westlaw Advantage bundle rather than sold as an accessible standalone product.
The gap this leaves for solo and small-firm lawyers
If you were a Casetext subscriber specifically because it was an affordable alternative to a full Westlaw or Lexis contract, CoCounsel Legal via Westlaw Advantage is a different value proposition — a premium product for firms already committed to, or moving toward, the Westlaw ecosystem, not a standalone budget option. Citation Safe does not attempt to replace Casetext's broad research capability. What we offer instead is a narrower, purpose-built, self-serve verification layer priced specifically for the solo and small-firm budget the original Casetext also served.
How to think about this if you're a former Casetext user
If your research needs were served by Casetext's AI-assisted case law search and drafting, you'll need a different tool for that specific job — whether CoCounsel Legal at its current price, a competing AI research platform, or manual research through a free resource like CourtListener. Whatever you choose for research, a separate, independent citation verification pass before filing remains worthwhile: reported hallucination rates for AI research tools generally, even sophisticated ones, are not at zero.
Why the shutdown matters for the broader legal AI market
Casetext's shutdown is a useful reminder that legal AI products, even well-loved ones, can disappear or be repriced entirely at an acquirer's discretion. This is one more argument for building your verification workflow around a specific, well-defined problem — citation accuracy — rather than around any single vendor's broader platform, since a narrower tool is generally easier to replace if a vendor changes course, shuts down, or moves upmarket the way Casetext's technology effectively did after acquisition.
What we can and can't promise about our own longevity
We can't promise Citation Safe will never change its pricing or product direction — no vendor honestly can make that promise, and Casetext's story is a good reason to be skeptical of any that do. What we can point to is a business model built around a narrow, well-defined, self-serve product for a specific underserved buyer (solo and small-firm lawyers), rather than a venture-backed platform play likely to get acquired and repriced upmarket the way Casetext was. That's a structural reason for optimism about accessibility, not a guarantee.
One more consideration
For lawyers who built their research habits around Casetext's specific interface and workflow over several years, the transition to CoCounsel Legal's different packaging and pricing is a real, disruptive change worth planning for rather than assuming it's a seamless continuation. If you're currently navigating that transition, it's a reasonable moment to also evaluate your citation verification process more broadly, since you're already reassessing your research tool stack.
Bottom line
Casetext's shutdown removed an accessible research option from the market; Citation Safe doesn't replace that research capability, but fills the accessible, self-serve verification gap the shutdown left behind.

Frequently asked questions
Is Casetext still available?
No, Thomson Reuters shut down the standalone Casetext product on April 1, 2025. Its technology lives on inside CoCounsel Legal.
Does Citation Safe replace CoCounsel Legal?
No. CoCounsel Legal is a full AI research and drafting assistant; Citation Safe is a dedicated verification tool that checks citations regardless of which research tool produced them.
Is there a solo-practitioner-priced alternative to what Casetext used to offer?
For citation verification specifically, yes — Citation Safe's tiers start at $12/mo. For broader AI-assisted research, the market has shifted toward either enterprise-priced platforms or general-purpose models like Claude or GPT-4 used directly.
Can former Casetext users get a discount on CoCounsel Legal?
Migration terms, if any, are a question for Thomson Reuters directly; we are not in a position to speak to their current transition offers for former Casetext subscribers.
