On the topic of Harvey, their pivot into signing up law firm clients directly is hiding a major concern for the legal industry. Harvey, and legal AI tools like it, will eliminate the need for large law firms. Not only are we seeing early signs of BigLaw exodus to start smaller and nimbler AI-native law firms who don't bill by the hour, but Harvey will likely replace the need for that large of outside counsel in the first place.

Google has also released a new Chrome feature (at least for paid Workspace users) that let's you generate a NotebookLM-style audio overview right inside of a PDF opened in a Chrome tab (no need to download it and upload it to NotebookLM). You can also right click anywhere on a page in Chrome and select "Open in Reading Mode" if you'd prefer to listen to a website verbatim rather than as an overview with an okay selection of AI voices.
