First in my bloodline to see 1 million line change PR getting merged (Bun's master branch is now rust, it's official)

Meet Carta Law: the largest AI-native law firm for private capital. Automation handles volume. Attorneys handle judgment. Fixed pricing replaces hourly billing. (We acquired Avantia Law to make it real.)

Anthropic just integrated Harvey AI as a connector inside the same release that ships 12 plugins doing what Harvey does. Harvey raised $200M in March at $11B. Legora raised $600M Series D last month. Their pitch: legal-specialized AI built on top of frontier models. That value capture only works if the model layer underneath stays neutral. It didn't. Tuesday's release: commercial counsel, employment counsel, litigation associate, plus 9 other practice-area plugins. Plus MCP connectors to Westlaw, CoCounsel, Box, Everlaw, DocuSign. The exact workflow stack Harvey and Legora built their valuations on, shipped natively inside Claude. Then Anthropic integrated Harvey itself. Which makes Harvey a data source feeding into Claude. The model layer said yes to powering Harvey. The model layer said yes to integrating Harvey. The model layer also said yes to shipping every product Harvey ships. Per Anthropic AGC Mark Pike, legal is already the #1 power-user job function inside Cowork with 3x the usage of any other function. A single webinar on legal teams using Claude pulled 20,000 registrations. Legal AI was already running on Anthropic. Tuesday removed the middleman. The next $11B legal AI valuation is the one nobody raises.


JUST IN: Anthropic rolls out new Claude tools aimed at automating legal work for lawyers & law firms.
