MayaClerk vs. Casetext CoCounsel
Last updated July 2026 · CoCounsel pricing is quote-only through Thomson Reuters; figures below reflect independent reporting. Verify with the vendor.
This comparison exists because of a gap in the market. Casetext built its user base as the affordable, technically modern alternative to Westlaw and LexisNexis — then Thomson Reuters acquired it in 2023, folded CoCounsel into the Westlaw product family, and moved pricing upmarket. The solo attorneys and small firms who made Casetext successful are the buyers this page is for.

|---|---|---|
| Pricing model | Published: free tier, $20/month Pro, $100/month Pro Plus | Quote-only; capability bundles reported at roughly $400–$700/month per seat, often sold with Westlaw Precision |
| Contract | Month-to-month | Enterprise agreements, typically annual or multi-year |

| Underlying corpus | MayaClerk's own 10.6M opinions, 100M+ passages, citation graph — no third-party content fees | Westlaw's editorial corpus, including secondary sources |
| Buying process | Self-serve signup, no sales call | Sales-led |
The honest capability comparison
CoCounsel on top of Westlaw content is a genuinely strong enterprise product — document review skills, deposition preparation, and drafting workflows that MayaClerk doesn't attempt, backed by Westlaw's secondary sources. If your firm is already a Westlaw Precision customer, CoCounsel is the natural add-on and this page won't talk you out of it.
MayaClerk's scope is deliberately narrower and deeper: primary-law research done extremely well. Hybrid semantic search over the full federal and state corpus, a citation graph you can walk in both directions, David for multi-step cited research, and litigation dossiers — structured research memos on a specific claim where opposing arguments are stress-tested and every quotation is programmatically verified against the source opinion before it reaches you. Dossiers are $39 à la carte, no subscription required.
The difference in philosophy shows up in verification. Generative legal AI's known failure mode is confident fabrication; MayaClerk's pipeline checks quoted language against the actual opinion text and flags what it can't verify, rather than asking you to trust the model.

Frequently asked questions
Does David hallucinate citations?
David researches against a fixed corpus and returns citations that link to the actual opinions; dossier quotes are additionally machine-verified against source text before delivery. Nothing replaces reading the case — the product is built so that reading it is one click away.
Can I get an API like Casetext used to offer?
Yes — a REST API over the full corpus at a flat $0.20 per call with prepaid wallet billing. API documentation here.
Is there a trial?
Better — a permanent free tier: 40 searches a month, no card required.
