Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Didomi

Pricing is based on monthly unique visitors and is not published, so a large publisher cannot estimate cost before entering a sales process, and traffic spikes translate directly into billing surprises.
Consent banners depress measurable traffic by design, and Didomi cannot prevent that, so publishers moving from a non-compliant banner should expect an immediate drop in tracked users and attributable conversions.
Certification is a moving target: Google and IAB update requirements periodically and each version change forces integration work on your side, not only on the vendor's.
Connected TV consent collection depends on the app platform and remote control interface, and implementations are considerably more involved than a web banner, often requiring per-platform development.
The wider privacy suite beyond consent is thinner than dedicated privacy platforms, so an organisation needing data subject rights automation and data mapping usually buys a second vendor anyway.

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.
