Are you looking for a tool that can diff legal documents line by line or clause by clause? If the latter I’d bet an LLM with a large context size could do a pretty good job, especially if you used a script (or another pass through the LLM) to break them down into like sections so that could just compare e.g. all Controlling Law sections with each other and all IP Indemnification sections with each other.
Now that I think about it, tuning the prompt (and keeping the temperature very low, like 0) you could probably get it to return everything from proper diffs to summaries of conceptual differences. And it could definitely do multiples at once if you were to break them into like pieces ahead of time.
You can kinda do it with Google Customizabe Search Engine, which is basically a thin wrapper around Google. In a regular Google search you can use syntax like -site:ignorethisdomain.com to exclude specific domains (i do this with Pinterest whenever searching for images, for example). But manually typing in a large list of black listed domains would be tedious so instead you can set up a CSE with everybody you want to ignore and then just use the special URL as your search engine.
I worked in a field that managed a lot of technology in retail stores. The big ones know everything about you, it’s just astonishing. At the time (around 15 years ago) there was very little oversight, but also most CIOs were inept and couldn’t really make the data sing and dance. Today that is very much no longer true, and it’s almost too easy to build a comprehensive profile of an “anonymous” guest and then attach it to their personally identifiable information, all without their consent or knowledge.
Is that pedal set up up to drive the machine, or is it just for looks?
