The short version
- Each has a real cost: Litera there is no published pricing or self-service option anywhere; every engagement starts with a sales quote, which makes early-stage budgeting difficult for a firm evaluating multiple vendors.; Westlaw firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- They diverge on capability: Litera covers Document comparison, Westlaw covers Case law and statute database.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Litera
- There is no published pricing or self-service option anywhere; every engagement starts with a sales quote, which makes early-stage budgeting difficult for a firm evaluating multiple vendors.
- The product is assembled from roughly a dozen acquisitions in two years, and modules originating from different acquired companies do not always share a consistent interface, which shows up as friction between drafting, comparison and contract AI tools.
- Reported costs at scale, $300,000-plus a year for large deployments, put it in a similar bracket to purpose-built AI vendors like Harvey, so a firm should genuinely compare the two rather than assume Litera is the cheaper, safer choice by default.
- Contract AI review functionality originates from Kira Systems, a 2021 acquisition, and firms should confirm how much that engine has been maintained and improved versus newer AI-native competitors.
- Modules may be licensed and priced separately even within one Litera contract, so a quote for "document comparison" does not necessarily include contract AI review or vice versa.
Westlaw
- Firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- Casetext no longer exists as an independent, cheaper self-serve product; anyone who liked its pricing and simplicity now has to buy into the Westlaw ecosystem, typically at a higher, seat-based cost.
- Multi-year contracts are structurally rewarded with the biggest discounts, which pressures firms into 2 or 3 year commitments before they know if usage will justify the tier chosen.
- Content and features vary meaningfully between Edge and Advantage, so an apparently small monthly price difference can hide the absence of Practical Law, which many firms end up needing anyway.
- Switching away from Westlaw means retraining staff on Lexis search syntax and the Key Number System has no direct Lexis equivalent, which is a genuine cost that suppresses competitive shopping at renewal.

Answered from the vendors’ own pages
Litera: Is Litera one product or several?
Functionally several. It combines document comparison (Workshare), contract AI (Kira Systems), deal management (Doxly) and drafting tools built or acquired separately, sold under one brand.
Westlaw: Can I still buy Casetext?
No. Casetext was retired on 1 April 2025. Its AI functionality continues as CoCounsel Legal, sold only as part of the Westlaw ecosystem.
Litera: Can I buy Kira Systems on its own?
Not as a fully independent product for law firms; Litera acquired the law firm side of Kira Systems in 2021 and it is now sold as part of the Litera portfolio.
Westlaw: Why does Westlaw publish some prices but not others?
Self-service online pricing exists only for solo practitioners and firms up to 10 attorneys; larger firms are routed to a sales representative with no public rate.
Litera: Is there a published price?
No. Every deployment is a custom quote; reported figures range from roughly $50,000 to over $300,000 a year depending on user count and contract volume.
Westlaw: What does CoCounsel Legal cost on top of Westlaw?
Reported figures put it around $639 per seat per month as an add-on, though this is not an official published rate and varies by contract.
