Community-built plugins from LegalQuants, launching as part of the OpenAI for Law ecosystem

Plugins for everyday BigLaw work.

Three plugins covering litigation, transactional work and AI education. Developed by top legal quants.

11 practising lawyers.
Five weeks. Three plugins.

Overview

The release includes three plugins with 37 skill entries across them:

  • Litigation — 15 skills: cite-check, client-update, correspondence, depositions, document-discovery, new-matter, organize-case-docs, pressuretest, docreview and writing, plus the five core skills shared with Transactional, below.
  • Transactional — 14 skills: definition-check, read-redline, sigpack, closing-checklist, closing-bible, conform, diligence, playbook-builder and playbook-review, plus the same five core skills.
  • Companion — 8 skills: legalquants, lq-apply, lq-ask, lq-connect, lq-mirror, lq-reflect and my-lq-moment, plus lq-start — the one core skill that ships in all three plugins.
  • Core — 5 skills, shared by Litigation and Transactional: regulatory, legaldesign, timenarratives, wiki and lq-start.

The plugins combine shared workflows with tools for particular practice areas. Each skill provides instructions for a recurring task, including how to review the material and check the output. Where applicable, results include a record of the checks performed and references to the underlying sources.

Checking citations against supplied authorities

The skill checks whether supplied authorities support a document’s propositions, quotations and pinpoint citations. It produces an HTML report with supporting excerpts, source locations and unresolved items, alongside a record of review coverage.

Contributor perspectives

On building the skills

John Hughes · On how the skills are tested

…we're testing these in many cases on documents that might be 30-50 or even 100 pages long and making sure that they catch everything.

Jamie Tso · On the project's beginnings

It started with around seven to eight core skills, which we think captured the canonical work for all AmLaw 250 lawyers.
