The short version
- Each has a real cost: Harvey there is no published pricing anywhere, and no self-service tier at all, so even qualifying for a quote requires an enterprise sales process most small and mid-size firms cannot justify starting.; 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: Harvey covers Legal research assistant, 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.
Harvey
- There is no published pricing anywhere, and no self-service tier at all, so even qualifying for a quote requires an enterprise sales process most small and mid-size firms cannot justify starting.
- 25-seat minimums put it structurally out of reach for solo, boutique and most mid-size firms regardless of interest.
- Reported additional platform fees on top of the headline per-seat licence mean the effective total cost is materially higher than the quoted seat price alone suggests.
- As a well-funded, fast-growing AI vendor, its product and pricing model are still evolving quickly, which is a real risk for a firm signing a multi-year enterprise contract now.
- Being trained and marketed specifically for BigLaw workflows means smaller firms evaluating it are comparing themselves against a product that was not built or priced with them in mind.
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
Harvey: Can a small firm buy Harvey?
In practice, no. There is no self-service tier, and reported 25-seat minimums and six-figure contract values put it out of reach for most small and mid-size firms.
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.
Harvey: How much does Harvey actually cost?
Nothing is published. Third-party reporting estimates $1,000-2,000 per seat per month and enterprise contracts from roughly $360,000 to over $1.5 million a year including platform fees.
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.
Harvey: Does Harvey replace Westlaw or LexisNexis?
No. It is an AI research, drafting and review layer, typically deployed alongside rather than instead of a primary legal research database.
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.
