Every legal AI tool, scored on the questions that end up in an incident report.
Where does the data rest? Does privilege survive normal use? Can you evidence what the tool did? What does the seat price become in year two? Eighteen tools, five weighted criteria, one method — and no vendor has ever paid us a penny.
Harvey
The enterprise legal-AI default: research, drafting and analysis over firm content, with the procurement paperwork to match the price.
Legora
A fast-moving assistant with strong tabular review and Word-native drafting; popular with transactional teams that want output they can edit, not just read.
CoCounsel
Research, summarisation and review anchored to a first-party citator — the most defensible answer in the category to the hallucinated-citation problem.
Vincent AI
Research assistant over a large international corpus, with citation-first answers and a breadth that suits cross-border work.
Spellbook
The easiest install in the category: a Word add-in that drafts and redlines where fee-earners already work. The trade is a thin evidential trail.
Definely
Defined-term navigation and drafting support built by lawyers who were tired of scrolling: strong on the mechanics of getting a document internally consistent.
Clearbrief
Brief and submission drafting with citation verification against the record — the rare tool whose main job is checking someone else's work.
Luminance
Contract review and negotiation at volume, sold on legal-specific models rather than general-purpose LLMs, with an established diligence pedigree.
Robin AI
UK-built contract copilot pairing software with human review services — pragmatic for firms that want the work done as well as the tool installed.
Juro
Browser-native contract collaboration and lifecycle tool with AI drafting assistance — strongest where the problem is process, not drafting.
LawGeex
Automated contract review against your playbook, mature as a rules-plus-ML system and consequently predictable — in both senses.
Kira
The diligence workhorse: pre-built clause models and extraction that a court or a client can follow, now being replatformed with generative features.
Relativity aiR
Generative review inside the platform the litigation market already uses — court-credible workflows with the newest layer honestly boxed as a first pass.
Everlaw
Modern, fast eDiscovery with a genuinely good user experience and transparent self-service pricing — rare in a category built on opacity.
iManage Copilot
Generative assistance inside the document management system the firm already trusts — the most boring and most defensible architecture in the index.
ndMAX
NetDocuments' AI layer: pattern-based drafting, summarisation and matter Q&A inside the DMS, with the same permissions story as its rival.
Thirdfort
Combined identity verification and source-of-funds checks built with law firms in mind — strong on evidence capture, weaker on the proportionality judgement regulation 33 actually requires.
Legl
Client onboarding, payments and AML workflow in one place, with a compliance-shaped audit trail that our reviewers can follow.
