Experienced team (Digital Shadows heritage)
Enterprise-only with no public pricing

Luminance pros and cons
Purpose-built for legal work rather than retrofitted from a generic assistant, with capabilities mapped to real workflows like drafting, negotiation, analysis, and compliance
Auto Mark-Up goes beyond flagging issues by suggesting redrafts that align contract language to a company's preferred positions
Knowledge Banks let teams encode their own clause logic and negotiation playbooks, so the AI reflects house standards over time
A Microsoft Word plugin keeps reviewers inside the editing environment they already use, lowering adoption friction in traditional legal teams
Pricing is not published and requires a sales conversation, making it hard to estimate cost or budget without a demo
Output quality depends heavily on how well teams curate clause logic and playbooks, so value is not immediate out of the box
As an enterprise legal platform, it carries meaningful implementation and onboarding overhead compared to lightweight tools
