  • They diverge on capability: Litera covers Document comparison, Relativity covers Large-scale processing.
  • 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.

Relativity

  • Quote-only and expensive, typically billed on data volume, so costs escalate with matter size
  • Complex enough that certified specialists are a job title, which is a real staffing cost
  • Considerable overkill for small matters, where lighter self-service tools are far cheaper

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.

Relativity: What does Relativity cost?

It does not publish rates. Ediscovery is generally billed on data volume and users, quoted per matter or organisation.

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.

Relativity: Is Relativity only for law firms?

No. Corporate legal departments and government agencies use it for investigations as well as litigation.

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.

Relativity: Do I need trained staff?

In practice yes. Relativity certification is a recognised specialism, and that staffing cost is part of the total.
