Harvey is valued at $11B. Legora just raised at $5.5B. I built their entire web application in two weeks and I'm making it open-source and free for everyone to use. Say hi to Mike: mikeoss.com. When I got the chance to try Harvey and Legora, I was surprised by how simple they were. A thought came to mind: I could probably build something similar in no time at all with Claude. And so I did. Assistant, project, tabular review and workflows. You get it all without vendor lock-in. Mike offers law firms an alternative, where they own the application layer and aren't stuck with a vendor they're renewing forever. You can try Mike in the demo on the website, or go to the GitHub link on the site to download the code and run a local version yourself.

Tbh I was kind of thinking they were a bit of a fad. But having learnt how behind traditional law firms are on AI they could actually bring innovation. It depends on what they are building internally. I imagine a lot just have some tools not too different from Harvey and Legora at this point. In which case they don’t bring any innovation. Some like Crosby charge like 500 for an NDA review which is ridiculous.

One of the tragedies of legal tech is that despite billions of dollars spent on distribution and teaching lawyers to use AI, nothing has really changed in the way legal services are delivered. Nothing has really changed for clients as well. The billable hour remains as strong as ever, billable hours stay constant, and prices keep going up year after year.

I think flaming is generally bad taste, but it’s also true AI affords us a level of abstraction where a real human job is developing normative takes about the technologies we pursue. in this screenshot thread I noted there’s persistent sense across the timeline that Harvey is a meme play for Boomers who want Secure Chat. @scottastevenson appropriately calls this Champagne AI. My smartest friends seem to want to work on AI plays that exploit some property of AI to introduce a new value proposition, structurally counter an old one, or expand service to an underserved audience. Harvey does none of these. It’s at best an expensive lifestyle product for the well heeled partner class. That seems to make for a good business, but we shouldn’t pretend that’s particularly interesting. AI has a bad reputation in part because it’s a product specifically for Capital. Harvey is a canonical example of this. Does Harvey make legal more accessible? Or change the business model of legal? No. No Sequoia think piece will change this. A partner at a Legora customer excitedly shared with me how they were using AI at the firm. I asked > cool so what’s in it for me > cheaper service? 😉 I got no answer. As AI races up the stack, discussion of norms and aesthetics is exactly the sort of human exercise we should expect to do more. Raising Prestigious Capital doesn’t excuse you from being responsible to questions like these — if anything it raises the expectations to have clear answers.

This is a wild way to market a lawyer asking some questions to an LLM behind a UI + custom prompt wrapper. I assume the target audience in Biglaw actually eats it up anyways. Harvey marketing team is always killing it. They have my genuine admiration. (0 sarcasm)

How does a seasoned Supreme Court lawyer prepare for the biggest case of his life? Using Harvey. Read how Harvey supported @neal_katyal in refining his arguments before the Supreme Court and how we are bringing those tools to law schools with Harvey Moot: harvey.ai/blog/the-supre…

@willchen500 Having been in Supreme Court moots, I find Harvey’s claim hard to take seriously. I think Katyal’s the newest celebrity spokesperson. Very good marketing indeed.

People say that Mike is a just vibe coded copy of Harvey but then they forget Legora was the OG in this respect Oh and Harvey is vibe coded as well. Any decent SWE will recognise vibe code instantly but lawyers can’t and they think they are getting some artisanal hand written code.
Zach Abramowitz@ZachAbramowitz

I’m not an investor in Harvey or Legora but I find it weird that all the hate has been directed towards Harvey when Legora is MUCH more hate-worthy Alright, flight taking off now, see y’all in a bit

@ElliotVaucher Just making the broader point. Yes it’s far from linux. Mike is a proof of concept. It is vibe coded and simple just like Harvey and Legora. If you try both on you’ll instantly recognise them as vibe coded apps and they don’t work very well either

While I do respect the approach, and agree on a lot of what you are highlighting in the legaltech industry (the money raised is mostly non sense), I think it’s a bit unrealistic to compare two weeks (could be an afternoon) of codex tokens thrown at a web app, that doesn’t even implement web search, to Linux now, isn’t it ? 🙃
WillC@willchen500

I was interviewed yesterday by The Australian Financial Review on Mike. The article notes the game-changing impact that Mike has had on the legaltech industry, less than a week after release. The article also features the first public comment from Harvey. Their spokesperson stated that "big proprietary platforms such as Harvey remained best placed to meet the intensive technology needs of law firms, including robust data security, around-the-clock support and access to a range of large language models." I agree on the security and service requirements of big law firms. But let me address the "proprietary" bit. A piece of software being private rather than open source does not equate to having technological moat, nor does it mean that it is secure. The idea that private = secure and open source = insecure is a pretty widespread misconception in the legal industry. Some of most secure and robust software in the world used by everyone, like Linux, is open source. Any modern piece of software is built upon the foundation laid by open source libraries, and that includes Harvey. It is precisely because of open source communities that we have these public goods.

@MitchJoWisco It’s just prompts. Also no lawyer is going to build an “agent” with an agent builder and then search through a 500 long list for his agent.

Mitch Jones@MitchJoWisco·
@willchen500 So is Harvey using “agent” in the actual AI coding context in that it independently uses tools or are the “agents” just prompts or workflows? From the widgets they show it looks like prompts - “extract key terms from documents” 4.6/4.7 are pretty good at that out of the box

@HedaSudhanshu Harvey’s ICP is the people can say that they are using AI without anything actually changing. Great for lawyers who hate change.
