AI-native platforms that augment legal work across multiple workflows — legal research synthesis, contract drafting and review, document analysis, due diligence acceleration, regulatory analysis, and legal writing — using large language models trained or fine-tuned for legal domain knowledge. Core capabilities include natural-language legal research with citation verification, AI-assisted contract drafting, document summarization and key-term extraction, due diligence automation, legal memo and brief generation, and multi-practice workflow support (litigation, corporate, tax, regulatory). The category spans purpose-built legal AI platforms (Harvey, Luminance, CoCounsel/Thomson Reuters) and AI-first legal tools (Legora, Spellbook, Robin AI) that embed in existing legal workflows.
