No you did not. No don't have the access to jurisprudence.

A lot of Harvey’s value prop is not in the underlying software - someone else came out with an “open source Harvey” (called “Mike”) months ago and it hasn’t really put a dent in uptake of Harvey or its main rival, Legora. Harvey’s value is in the infrastructure, the help integrating it into workflows, the ability to represent to other parties that you are using a trusted provider.

Harvey can be pretty useful and has all sorts of tailoring done to it to provide utility to legal professionals. I don't really see any of that here. Like someone else pointed out, the main benefit of Harvey is being able to say "well we used the leading legal AI provider." Let alone the staff to get the old fogeys at my firm using it..

> CaseCite is a _source-available_, self-hosted legal RAG caselaw research & document analysis platform. Source-available is not open source.

Just like how DocuSign should have shut down after thousands of other open source clones have spawned on GitHub? (DocuSign is still alive) Also "source available" is not "open source". On top of that even releasing the source must mean that DocuSign and Harvey should be panicking right now. /s Can someone please tell them that they should be scared?

I build my own take on this with https://document.bot Build for aviation legal regulations/ compliance. Highly optimized search around large PDF's, Word, etc with offline, EU and frontier LLM options.

Which LLM model actually built this? I looks very sloppy.

This is not open source! Can we get an update to the title?

> I built the same and open sourced it How can I *trust* you its true? Will you bet your money its __the same__ ?

Friend works for a fairly large law firm on the business running side. She told me how they pay a ton for Harvey and yet, they don't even have a claude for her and those not doing legal work. They think Harvey is great and have no clue that all it does is wrap around models and have safety checks like this repo does. Some of it might be yes, that there's legal work around who gets blamed, but I see mentions of Harvey and it's a joke at what the legal industry does. I see law firms as having no clue on how things work other than paying giant contracts to places that like to schmooze them because that's what they like to do as well.

I guess my first questions would be: what kind of background does the creator have in law to be able to steer this system to a good outcome? If they don't have a legal background, were legal experts and otherwise consulted to build this out? The fact that the creator is struggling with even understanding what open source is, makes it much harder to put any faith in this system.

This is incredible stuff OP Why is this being flagged? This is literally what CodeCradt did!
