    As a lawyer, I'm excited about this, but there are two roadblocks that I'm not sure how Anthropic will navigate:

    (1) For non-lawyers who use these skills/connectors/whatchamacallits to try to get legal advice, their communications are not protected by attorney-client privilege. This will absolutely bite some people in the ass.

    (2) If a lawyer uses this with confidential client information (which, to the uninitiated, doesn't just mean SSNs and bank account numbers, but "all information relating to the representation of a client") and forgets to toggle off "Help improve Claude" in their settings, they have possibly (maybe even likely) committed malpractice.[1]

      Slightly related: Amazon’s bedrock has better privacy guarantees. This seems to be skills that can be added to Desktop app, which can connect to Bedrock for inference.

      Citation for #1 - https://harvardlawreview.org/blog/2026/03/united-states-v-he...

      > Judge Rakoff of the Southern District of New York — addressing “a question of first impression nationwide” — ruled that written exchanges between a criminal defendant and generative AI platform Claude were not protected by attorney-client privilege or the work product doctrine.

      Much more to it than this one-liner that I pulled out, but safe to say, don't rely on or put your legal defense etc. (or elements of it) into AI unless you want it discovered.

      (not a lawyer, unlike OP, who might be able to refine what I highlighted with more precision)

        In the US, are Google queries about the law considered attorney-client privilege? What about library records? Browser history? Google Maps / Uber / car travel history (when traveling to an attorney's office)?

        If somebody Googles "best attorney for murder NYC" a day after a murder is committed but before any case is filed against them (so they clearly had some reason to expect that case), could that be used as evidence?

      • dolebirchwood 11 hours ago ago

        > exchanges between a criminal defendant and generative AI platform Claude were not protected by attorney-client privilege or the work product doctrine

        Shouldn't that have been relatively clear to all parties involved? Maybe not to the defendant, who's apparently clueless.

        The AI platform is not an attorney. A defendant's communications with an AI platform are therefore not communications between a client and their attorney, nor will the AI output constitute attorney "work product" because the AI platform is not an attorney.

        Doesn't really come across as a novel problem, aside from AI being involved. I'm sure countless defendants have made the stupid mistake of talking about the facts of their case to persons other than their attorney, and those communications came back to bite them in the ass when discovered.

      • clickety_clack 11 hours ago ago

        Can anyone be your lawyer, or does a lawyer have to be certified somehow?

        • xboxnolifes 11 hours ago ago

          It is my understanding that they must be certified. You are allowed to represent yourself, but it is my understanding that a non-lawyer cannot represent you.

        • engineer_22 11 hours ago ago

          You have to be admitted to the bar to practice law. Which is to say, other lawyers must recognize you as a lawyer, and this recognition can be taken away.

          • john01dav 10 hours ago ago

            More practically, this means (in America) that you need a JD degree (4 year grad school), to pass an exam, and pass a(n oftrn horrifically thorough) character background check.

    • nerdsniper 11 hours ago ago

      For (1) it's so wild to me that if I pay a lawyer, they can run the same queries on these tools and they are protected by attorney-client privilege, but if I do it to help me prepare my defense, then the exact same queries would be subject to subpoena/discovery.

      Does anyone know if there exists any OPSEC procedure for me to use third party tools like this for my own concerning legal questions that is both ethical and allows me to be confident that my interactions won't land in discovery documents?

      • tjohns 10 hours ago ago

        If you are preparing for your own defense and don't have an attorney (you're acting pro se), your own LLM use would likely be protected under work product doctrine. The court would extend you some of the same protections an attorney would have, for the limited purposes of preparing your case.

        This is a very narrow exemption, however.

        (You would also want to make sure you're using a paid AI plan with contractually guaranteed privacy protections, otherwise it could be construed as third-party communications, which implicitly waives privilege.)

        See: Warner v. Gilbarco, Inc.

        > Does anyone know if there exists any OPSEC procedure for me to use third party tools like this for my own concerning legal questions that is both ethical and allows me to be confident that my interactions won't land in discovery documents?

        Isn't that a fundamental misunderstanding? Would "OPSEC" like that amount to destruction of evidence or contempt of court or something like that?

        Like if all your incriminating documents are on some encrypted drive, it's not like that defeats discovery. You're supposed to decrypt them and hand them over.

        • nerdsniper 10 hours ago ago

          That’s absolutely part of my question. I’m not familiar enough with discovery to fully understand this.

          • bombcar 7 hours ago ago

            Discovery in a criminal trial is more limited than in a civil trial.

            Your only real defense against discovery is to not have said it, or to have destroyed all records of it before the hint of discovery wafted on the wind.

      • JumpCrisscross 11 hours ago ago

        > if I do it to help me prepare my defense, then the exact same queries would be subject to subpoena/discovery

        We need a law where someone can clearly designate a chat privileged, with severe consequences for mis-use.

      • tptacek 11 hours ago ago

        Wouldn't that same logic exclude evidence from Google searches, like "how to get away with murder"?

        • nerdsniper 10 hours ago ago

          Yes? Which makes it feel like the answer is just “No.” Unless you use Mullvad, TailsOS, and don’t log into the service. But I’m not sure if that’s “ethical” for Google/DDG searches and it’s not really possible for Claude/Kagi. I would assume that simply using a “secret” account isn't a magic way to avoid discovery either.

        How's this any different than any professional license? You're basically paying for preferential treatment from the state in a given subject area.

          > How's this any different than any professional license? You're basically paying for preferential treatment from the state in a given subject area.

          Because it's got nothing to do with the professional part? Licensing should affect their practice of law, sure, but it shouldn't grant random other privileges.

        Self host your own LLM

        • singleshot_ 11 hours ago ago

          Why do you think this would be less discoverable than hosting your own email server?

          • QuadmasterXLII 11 hours ago ago

            If you use a stateless client (like just rawdogging cli llama.cpp) there’s nothing to discover. Setting a program with an option to have logs to not do that could conceivably get you in trouble but using a widely used program that never had logs seems like it has to be fine. Maybe they could nail you for googling “which local llm approach generates logs?” also, don’t get nailed by your bash history!

          • kevin42 11 hours ago ago

            Because you don't keep logs.

          • AndrewKemendo 8 hours ago ago

            Because nobody would know about it unless you told them for some reason

        • nvr219 11 hours ago ago

          You’d need to hand that mac mini over if subpoenaed

          • AndrewKemendo 8 hours ago ago

            Can’t hand over something that doesn’t exist if it’s running in a VM container and gets destroyed every 12 hours

    • SkyPuncher 11 hours ago ago

      For #2, I’d expect you’d use this through an organization/business account that has data retention turned off by default.

    • tjohns 10 hours ago ago

      #1 is a little complicated. Communications with an AI are possibly sometimes protected by work-product doctrine... but only if you're representing yourself as a pro se litigant, and strictly limited to mental impressions and opinion work product of counsel (in this case, extended to the pro se litigant). See: Warner v. Gilbarco, Inc.

      There's a good summary of the current state of things here: https://www.akerman.com/en/perspectives/ai-privilege-and-wor...

      Also worth noting that none of this is binding precedent, so expect this field to evolve over time.

    • colechristensen 11 hours ago ago

      In the legal world are there certifications for handling privileged information?

      For example in the medical world if you are a provider covered by HIPAA you must have a signed "Business Associate Agreement" with any party that handles the covered protected health information (PHI).

    • bethekidyouwant 9 hours ago ago

      It’s a bit of a moot point because the amount of times that your AI logs are going to be subpoenaed in your court case approaches zero.

  • unstyledcontent 11 hours ago ago

    Just remember that your AI chat history is not protected like attorney client privilege and can be used as evidence against you in court. If you talk to a lawyer and they use AI, those chats are privileged.

    • singleshot_ 11 hours ago ago

      No. If you talk to an attorney and they take reasonable precautions to maintain the integrity of the confidential attorney client relationship, the privilege is preserved. If not, not preserved.

    • bethekidyouwant 9 hours ago ago

      I don’t understand this situation .. where in your court case the prosecutor asks a judge to get a warrant for your AI chat logs … this is just not gonna happen.

      • MrDarcy 9 hours ago ago

        IANAL but I believe discovery is where this would happen.

    It seems like they ripped out Lexis, which is probably one of the most important tools for lawyers: https://github.com/anthropics/claude-for-legal/pull/5.

    • dolebirchwood 11 hours ago ago

      > at partner request

      Curious if Thomson Reuters (Westlaw) felt threatened if they were this compelled to moan about it. All it does is make me wonder how well these skills perform when paired with Lexis (if possible?) instead of Westlaw.

  • prima-facie 8 hours ago ago

    As someone who has represented themselves in tribunal before I'm definitely interested in this.

    The only issue is that in some jurisdictions, like the UK, you can't just offer someone legal advice without being SRA accredited or FCA regulated. I.e. this would effectively make Anthropic a claims management firm under the UK law.

    > Under article 89I of Financial Services and Markets Act 2000 (Regulated Activities) Order 2001 ("The Order"), advising a claimant or potential claimant, investigating a claim and representing a claimant, in relation to a financial services or financial product claim is a defined regulated activity.

    I'm a bit bothered by this line. Does it mean this is based on customer's sessions? Are they entitled to build knowledge bases for every profession, topic and workflow in the world using customer data?

      And in what country? They know that the law is different in every country right?

    • lionkor 11 hours ago ago

      Yes they are training on your business's data so that their AI can replace your business later. If you don't believe it, name one thing they didn't train on.

      • hirsin 11 hours ago ago

        It definitely looks like the old tale come true - at Microsoft people would warn against using Google because then Google could figure out what we're working on, since it was pretty easy to tell where a query was coming from.

        Sounded far fetched back then, and on the face of it illegal, but now it's just common sense I imagine.

      I mean, the laws are written down somewhere though. A human can still look at the actual law and surmise that the AI is feeding them bullshit.

      • macintux 10 hours ago ago

        I think the problem is that laws overlap, with decades of case law clarifying their interactions. Looking at one law probably isn't enough to determine whether an LLM is lying to you.

  • TrackerFF 10 hours ago ago

    This is why I think many of the current application-layer AI startup valuations are a bit iffy. When the big AI companies like Anthropic start expanding their vertical products, the calculus changes.

    I'm just wondering how committed they'll be - I guess the edge some startups still have, is the fear that product suites from OpenAI / Anthropic / etc. will go the way of Google products, a year or two then straight to the morgue.

    • matusp 4 hours ago ago

      It's like asking what if AWS starts doing it, they have all the infrastructure in place. LLMs are just one cog. There is a lot on the application side they are not doing at all.

    • bigstrat2003 10 hours ago ago

      Every valuation in the AI space is iffy. Nobody actually has a solid business plan, only vibes, but that isn't stopping people from throwing money at them.

  • lostathome 10 hours ago ago

    I wonder what clients would think if they discovered their lawyer uses a chatbot with their confidential story. Even with redaction, patterns still emerge. Certainly I wouldn't be happy in any case.

    I see this as a strong case for private AI, or an in-house stack.

    Or I have to be missing something.

    This seems like a shot across the bow for all large Claude API customers, which I'm sure they saw coming.

    But still, a TSMC style pure play model provider would win huge business in the space given how many application companies are being eaten by model companies.

    Anthropics New Playbook:

    `/loop 2days /create-new-{insert-industry}-md-files`

    This is only for PR. No one checks what's in those docs, or if these are real, valid or ethical. The goal here is for all news outlets to pick them up. You're not the audience.

    Given the amount of free PR they can get from some AI-generated .md files, I'd probably do the same if I was on their boat.

    Right now, I don't think any other AI company generates as much as slop as Anthropic does.

        I assure you, in most democracies, most people are jerked around by other people acting in bad faith far more often than their government acting in bad faith.

        Landlords, tenants, vendors, business and former romantic partners, clients, banks, even your local gym is way more likely to try to fuck you over than the government is.

    • gosub100 11 hours ago ago

      I would love this for poor people to fight giant corporations via 'lawfare'. It's largely unethical (just like many corporations) but just knowing how to file junk lawsuits that cost corporations millions to fight would be nice.

      I dont mean 'frivolous' like prisoners who file pro-se about their ice cream melting [1], but a level or two above that , that costs time and money to produce records and testimony to defend, even if nary a dime is paid out. Basically ask GPT to figure out the terms and theories to file to get your lawsuit accepted, and done by poor people who cannot afford to post $ or repay if they lose. aka "asymmetric warfare" that benefits the little guy, just like the kind private equity or other terrible corporations wield against the poor via"mandatory arbitration" clauses or damages caps and similar rules that always benefit corporations.

      >Imagine the shenanigans someone can achieve with that user.

      First step out of line and that account along with anything remotely connected will be banned to oblivion.

      Given they share models on Azure, Anthropic will have someone at Microsoft on speed dial.

      I've even seen disconnected commit hashes disappear during their security responses which the repo owner has no way of removing.
