## Buyer Intent Signals
Problems: Free Public Legal Databases (Manual): Using Google Scholar, government law libraries, and physical court records. | Legal Research Agencies: Hiring specialized legal research firms or freelance paralegals. | Legacy Firm Folders: Relying on internal firm knowledge and previous case files without updating research.
Solutions: best legal research platform for lawyers | case law database with annotations | affordable legal research for solo practitioners | AI tools for legal brief analysis | Thomson Reuters legal research tool | Generic AI Chatbots: Using general AI bots like ChatGPT or Claude for preliminary research (risky due to hallucinations).
