About

Junior JR3 is an AI-centric legal document platform built for drafting, reviewing, researching, and completing legal work directly inside Microsoft Word and Google Docs. Its document library provides purpose-built workflows, playbooks, skills, sequences, and rules for legal document types across multiple practice areas, allowing firms to apply their own standards, prior work, and drafting style. AI repositories, prompt libraries, agents, writing styles, and training datasets sit above the underlying models, so teams can use OpenAI, Anthropic, Google Gemini, or privately deployed models and switch between them without rebuilding workflows. For patent and trademark work, JR3 connects directly to live USPTO, WIPO, EPO, federal case law, and state case law data. Its tools support Office Action responses, examiner-focused drafting, patent searching, claim charting, appeal briefs, opinion letters, legal memoranda, assignments, NDAs, and other documents.

About

Lucio is the legal intelligence workspace built for law firms and in-house counsel. Founded by Darsan Guruvayurappan and Vasu Aggarwal, Lucio brings AI to drafting, review, research, and compliance through Lucio Assistant, Lucio for Word, and Lucio for Outlook. Each sits inside the tools lawyers already use, so intelligence lives in the document, the email, and the matter, not in a separate app. The platform helps with reducing time spent on repetitive tasks, and improving accuracy so lawyers get back the time to focus on complex-high value work. Founded in India with offices in New York, Lucio AI has raised $5 million in seed funding and is expanding aggressively across the US and UK legal markets.
