Harvey, Thomson Reuters CoCounsel, Spellbook, Robin AI, Ironclad, Luminance, Kira, Evisort, vLex Vincent, Westlaw Precision, Lexis+ AI, Relativity aiR, Everlaw, DISCO — by May 2026, more than 80 percent of AmLaw 100 firms are piloting AI, and roughly 30 to 40 percent have crossed into production. Contract drafting and review, legal research, e-discovery, M&A due diligence, memos, translation, and compliance — almost every layer of the lawyer workflow is being redrawn. At the same time, the Mata v. Avianca sanctions showed how hallucinated citations can ruin careers, and the GDPR collision with attorney-client privilege has not been settled. This guide maps the major tools with real specs and pricing, the Korean and Japanese ecosystems, open-source alternatives, and the agentic future where routine matters run on autopilot.

Avianca事件のようにハルシネーション引用で制裁された弁護士もおり、GDPRと弁護士・依頼者間特権の衝突は未解決のままだ。本ガイドは主要ツールの実機能と料金、韓国・日本のローカルエコシステム、オープンソース代替、そしてAIエージェントがルーチン案件を処理する将来像までを整理する。 Sat, 16 May 2026 00:00:00 GMT fjvbn2003@gmail.com (Youngju Kim) ai-legallegal-techharveycocounselspellbookrobin-aicasetextvlexrelativitycontract-analysis日本語 https://www.youngju.dev/blog/culture/2026-05-16-ai-legal-tech-2026-harvey-cocounsel-spellbook-robin-ai-casetext-vlex-vincent-relativity-aire-deep-dive https://www.youngju.dev/blog/culture/2026-05-16-ai-legal-tech-2026-harvey-cocounsel-spellbook-robin-ai-casetext-vlex-vincent-relativity-aire-deep-dive AI 리걸테크는 2023년 ChatGPT 충격 이후 가장 빠르게 LLM을 흡수한 수직 영역 중 하나다. Harvey, Thomson Reuters CoCounsel, Spellbook, Robin AI, Ironclad, Luminance, Kira, Evisort, vLex Vincent, Westlaw Precision, Lexis+ AI, Relativity aiR, Everlaw, DISCO — 2026년 5월 기준 AmLaw 100 펌의 80% 이상이 AI를 파일럿하고, 30~40%가 프로덕션 배포 단계로 넘어갔다. 계약서 작성·검토, 법률 리서치, e-discovery, M&A 실사, 메모 작성, 번역, 컴플라이언스까지 — 변호사 워크플로의 거의 모든 레이어가 다시 그려지고 있다. 그러나 Mata v. Avianca 사건처럼 환각 인용으로 제재받은 변호사도 있고, GDPR과 변호인-의뢰인 특권의 충돌도 풀리지 않았다. 본 가이드는 주요 도구의 실제 기능과 가격, 한국과 일본의 리걸테크 생태계, 오픈소스 대안, 그리고 2026년 이후 AI 에이전트가 루틴 업무를 처리하는 미래까지 정리한다.
