25 Best AI Tools for Lawyers: Types, Benefits, Research, Drafting, and AI Chatbots

1. CoCounsel Legal

CoCounsel Legal is an AI-powered legal research and drafting platform from Thomson Reuters that helps lawyers analyze judicial opinions, review documents, summarize legal authorities, and prepare legal work product. Its integration with Westlaw and Practical Law connects generative AI assistance with established legal research resources.

CoCounsel supports litigation research, document comparison, legal memorandum preparation, and case analysis. Lawyers use the platform to locate relevant authorities, review extensive document collections, and organize research findings into draft legal arguments. Westlaw’s KeyCite services also support evaluation of citation treatment and precedential status.

CoCounsel is particularly suitable for law firms that already use Thomson Reuters products and require connected research and drafting workflows. Attorneys must still review generated arguments, verify legal citations, and confirm that the source material supports each legal conclusion.

2. Lexis+ with Protégé

Lexis+ with Protégé is an AI-powered legal research platform that combines conversational research, legal document analysis, drafting assistance, and Shepard’s citation verification. LexisNexis provides the system through its legal research ecosystem, including primary and secondary legal materials.

Lawyers use Protégé to ask legal questions in natural language, locate relevant authorities, summarize judicial decisions, and prepare research-supported drafts. Shepard’s helps attorneys evaluate whether a case has received negative, positive, or distinguishing treatment from later courts.

Lexis+ with Protégé is suitable for litigation practices that prioritize precedent verification, jurisdiction-specific legal research, and connected drafting workflows. Its source-grounded approach assists research, but attorneys remain responsible for verifying authorities before citing them in court filings.

3. Harvey AI

Harvey helps lawyers review contracts, extract important clauses, organize legal arguments, and analyze large document collections. Corporate attorneys use Harvey during transactions to examine agreements, identify contractual obligations, and prepare due diligence summaries.

Harvey also supports internal knowledge retrieval and repeatable legal workflows. Enterprise adoption requires evaluation of document security, software integration, attorney supervision, and the quality of generated legal analysis.

4. Spellbook

Spellbook is an AI contract drafting and review tool that works inside Microsoft Word to help lawyers generate clauses, review agreements, and suggest contractual revisions. Its functions include automated redlining, contract analysis, playbook comparisons, and drafting assistance.

Spellbook is particularly useful for transactional attorneys handling nondisclosure agreements, commercial leases, master services agreements, and vendor contracts. Lawyers use its review functions to identify unusual contract language, propose alternative provisions, and compare agreements against preferred drafting standards.

The platform reduces repetitive drafting work while keeping contract editing inside Word. Attorneys must determine whether suggested clauses reflect governing law, client objectives, commercial risks, and the agreement’s other provisions.

5. NotebookLM

NotebookLM is Google’s AI-powered research assistant that helps lawyers summarize uploaded documents, locate information within case files, and generate answers supported by source citations. Its research workflow focuses on documents provided to a notebook rather than automatically supplying a complete professional legal research database.

Lawyers use NotebookLM to examine deposition transcripts, witness statements, contracts, correspondence, and other approved case materials. A litigation attorney can ask the system to identify statements about a particular event, compare references across documents, or prepare an initial chronology.

NotebookLM includes citations that direct users to supporting passages in uploaded materials. Attorneys must verify generated summaries and assess applicable confidentiality, privilege, and data-handling requirements before uploading client records.

6. ChatGPT

ChatGPT does not automatically provide the legal source coverage or citation-treatment verification available in specialized legal research systems. Lawyers using ChatGPT for legal drafting and research must verify legal propositions and apply appropriate safeguards when handling client information.

7. Claude

Claude supports preliminary contract analysis, legal memorandum drafting, internal research summaries, and correspondence preparation. Its document processing features help attorneys identify relevant sections and organize complex material into readable formats.

Claude is suitable for general legal productivity rather than serving as a substitute for a professional legal citator. Attorneys must independently confirm generated case references, statutory interpretations, and legal conclusions.

8. Google Gemini

Google Gemini is an AI assistant that supports document analysis, drafting, information organization, and productivity tasks across Google’s software ecosystem. Lawyers use Gemini to prepare written materials, summarize information, and organize internal workflows.

Google Workspace integrations support selected activities involving Gmail, Google Docs, and other applications, depending on the organization’s subscription and configuration.

Lawyers use Westlaw’s AI research functions to identify relevant cases, examine legal issues, and connect research findings with established Westlaw resources.
