Best Use Cases
Ehsan's Growth Take
After the lawyer-uses-ChatGPT-and-cites-fake-cases disaster, verifiable citations became the table stakes of legal AI. Casetext was ahead of that curve. CoCounsel cites real cases with accurate holdings 92-95% of the time. That last 5-8% still requires attorney verification, but it reduces research time from 4 hours to 45 minutes on complex legal questions. At $250/mo, it replaces $5K/mo of junior associate research time.
