    The media response to this omits the fact that these vibe coded "reverse engineered" apps hardly work and we've had open source alternatives to the Microsoft and Adobe products for years. The narrative they're pushing is a frontier model can make a perfect clone of any app, and the reality is it makes a ui that looks somewhat similar but none of the functionality actually works.

      Hah, Potemkin Office Suite. Next, Potemkin OS and Potemkin phones?

      Maybe that's many are convinced AI can replace developers, they can only see the surface of software and think there's not much more underneath it...

      • nradov3 hours ago
        In the case of Microsoft Office native desktop applications the LLMs can figure out everything underneath through a mix of decompiling the binaries, reading the product documentation, and exploratory testing. Some SaaS is more opaque.
    • nonamee4 hours ago
      The narrative has a point. The LLMs are getting very good at this task. I got 95% of functionality by using LLM to port our Qt desktop app to thin web client and web server. Astra medium, two prompts, 2 hours of LLM processing. Each of two LLM plans had about ten steps. The missing step for porting of these apps is to test against the original (ex. Ms office) app in the plan.

      I don't know but this WordCraft works perfectly fine hasn't crashed on me and has 90% of the features already there.

      Not to mention it's single binary barely 80 MB and super fast to start and very snappy.

      Have you tried that or that PDFCraft?

      Also wake me up when there’s a cloud version that works in an even vaguely similar way.

      The Office advantage is a suite of apps and integrations with their cloud offerings. That’s their big moat against vibe-coded apps, because few vibe-coders want to maintain a SaaS service for Office files and even fewer CIOs want to commit their company to use that service when Microsoft exists and is proven to work.

      • dgellow5 hours ago
        Looking at the website they seem to mention a web version: https://getartcraft.com/ (I haven’t tried though)

        > Also wake me up when there’s a cloud version that works in an even vaguely similar way.

        NextCloud has had an office suite offering for many years.

        • freeone30004 hours ago
          The web versions are passable, but the native versions are non-extant, and the handoff story leaves much to be desired. You can’t, say, have one person editing native and one person editing on web.
    • ocdtrekkie5 hours ago
      Yeah though FWIW, the overall impact of companies realizing maybe they shouldn't be spending $100k a year on a document editor is likely to raise all boats for alternatives.

      It remains really wild people think Office is worth $30/month/user. Anything that erodes that belief is a net positive.

      • awesan5 hours ago
        i dont think anyone thinks it's worth that on its own, but you need some kind of user management (entra id in this case), some kind of cloud storage (sharepoint in this case) and some kind of standard document format (docx, xlsx, pptx in this case) in any company.

        of course you can do all that with open source stuff but office is just easy to buy and hard to get rid of once you have bought in. the bigger your company the harder it is to migrate.

        • ocdtrekkie5 hours ago
          Entra ID is separate if you don't want logins from Nigeria. One of the most insane-to-me things is Office 365 is basically "open access by default" and you have to pay $6/month/user to fix it. Most people don't realize just how much attack surface they open up moving their data to the cloud, and that it costs a lot to even start to get back towards a secure environment like you had on-premise.

          But yeah, the lock-in effect is huge. Microsoft cloud products deliberately don't work well with anything but more of their own cloud products. And as soon as you start a migration to it based on what you need, you suddenly realize how much other stuff you also need to pay them for. And you can't escape without replacing all of it.

      • variety86755 hours ago
        I think a lot of people forget about the labor costs of migrating. The $30/mo looks cheap compared to all of the time spent trying to teach end users how to use something else
        • nradov4 hours ago
          Part of the potential of these vibe coded clones is that the UI and workflows will be very similar to the genuine Microsoft products. So if they're actually completed and debugged then a migration won't necessarily require end user retraining.
      • stephbook4 hours ago
        You've fallen prey to the "Everyone is stupid except me" fallacy.

        By the time you add cloud-storage space integration (SharePoint), live collaborative editing, support hotline, support for 30 year old macros, and Active directory user integration, you'll be charging the same per seat.

        But hey, proof me wrong please. Code it.

        • ocdtrekkie4 hours ago
          > support hotline

          Have you... ever tried talking to Microsoft support?

      • dgellow5 hours ago
        Paying for software is perfectly fine. If people don’t want to pay for office there isn’t a lack of alternatives at all. Google doc is right here for them to use of they want a free cloud version.

        The idea that companies with subscriptions are extorting users is cancerous nonsense

  • sombragris15 minutes ago
    I don't buy the hype on these vibecoded apps, but I think an interesting use of this methodology would be to revive proprietary applications that were axed by their owners.

    For example, what about a new clone of Macromedia's Free Hand? or Adobe's Page Maker? Or MS Front Page, vibecoded to be compliant with the latest W3C standards?

  • sega_sai5 hours ago
    I'd rather wish people put effort into LibreOffice. I'd hoped there would be significant improvements there as there is a huge scope of bug/compatibility fixes. But I guess it is not sexy enough.
    • mjr005 hours ago
      Yeah, this entire saga is really unfortunate. The narrative is really enticing (AI is obsoleting Adobe/Microsoft/other corporate software behemoths!) when the reality is it's a vibe-coded slopware that barely functions, according to anyone who has actually tried it, and there are other FOSS alternatives which are much more stable, mature, and deserve people's attention. I wonder how many people shouting "Claude vibed a Photoshop clone, Adobe is done!!" were even aware Krita or GIMP existed.
    • mikert895 hours ago
      im willing to bet its easier to generate a new office than it is to fix libreoffice
      • probably_wrong5 hours ago
        I'm willing to take the other side of that bet. Quoting this article [1]:

        > The idea that new code is better than old is patently absurd. Old code has been used. It has been tested. Lots of bugs have been found, and they’ve been fixed. There’s nothing wrong with it.

        LibreOffice has to be feature-per-feature, bug-per-bug compatible with a poorly-documented office suite that's been around for 35 years, so it's no surprise that they don't always get it right. I don't see a new office suite doing any better, unless they decide that compatibility with MS Word is no longer a priority.

        • throwaway20464 hours ago
          OnlyOffice, despite being newer than LibreOffice, has better compatibility with office documents and is way ahead in terms of UI. Plus it runs on Linux.
          • andai4 hours ago
            The difference is OnlyOffice actually wants to make money. Which means it needs to be good.
      • lelanthran5 hours ago
        If you want a new "office" that doesn't work, sure, but you don't need AI for that.
    • egeozcan5 hours ago
      Do they even allow AI contributions? I'd love to contribute if they do.

      Some people tell me why not donate instead, and the reason is the same as me giving people actual presents instead of gift cards: I take the time to choose and understand an issue, spend time on it, just like I spend time picking a present. Both are riskier than giving money directly, but the euphoria of having my PR get merged or present being appreciated is addictive :)

      • mft_2 hours ago
        This is a really interesting possible difference. Legacy open source seems to be generally trending anti-AI (although I don’t know the exact stance of LibreOffice). These new vibe-coded Adobe/MS copies are obviously AI-friendly.

        Time will tell which wins.

    • glimshe4 hours ago
      I'd rather not. LibreOffice is terrible and probably unfixable. It's certainly better than these vibecoded alternatives, but not where the effort should go. We need new leadership in the open source office space.
      • Emoticon40322 hours ago
        Just curious… why do you think that? We have been using LibreOffice in our company for 20+ years, exchanging files with customers and vendors who use MS Office in all its versions during this time. We never had a problem…
        • sombragris21 minutes ago
          Lawyer, translator and professor here. I have an Office 365 subscription and I got native Word and other MS Office apps installed on my windows partition. But, since I use Linux on the desktop, and MS chose not to offer their office suite as Linux native apps, and they make it near impossible to use the Windows apps under Wine, I use LibreOffice.

          And it works really well. I can use it and exchange documents with people using Word without problem in the enormous majority of the cases.

          And the fact that LibreOffice is a real GUI app built using the WIMP paradigm instead of that stupid ribbon interface that forces me to use the mouse, is a very significant net positive for me.

          People who say that LibreOffice has a bad UI or that is a bad piece of software are just more vocal.

    • dbg314155 hours ago
      It is not sexy enough.

      It has atrocious UX. Crazy bloat from promising to support every one-off file format under the sun for the last 25 years.

      Trying to get a PR commit committed is like dealing with an entire army of bureaucrats.

      So I get it would be great (in theory) if people wanted to support this, but at the same time it’s too far behind —- and the team is too entrenched in bad UX decisions, ackward support mandates for obscure systems that in reality nobody ever really used.

      And this is a hill I’ll die on… Permissive licenses > copyleft. If I fork your code, as long as I put your name in the credits, the code is mine to do whatever I want with. Past authors shouldn't get a say in what I build next. That's real open source.

      • mehdix5 hours ago
        Can relate to that. Nowadays it's much easier for me to fork a project and fix the bugs for myself rather than convincing the maintainers that my niche bug is worth a fix and the fix is worthy.

  • dariosalvi785 hours ago
    I've been thinking about this these days, this is the final revenge of open source. After having ingurgitated all the open source projects there exist in the world, AI is making basically all software un-copyrighteable (yes, you can't copyright a picture made by AI as you can't copyright a piece of software made -entirely- by AI).
  • giancarlostoro7 hours ago
    Yep, I realized this back in February, you can remake basically anything in a drastically shorter span of time with a single frontier model and patience and test thoroughly.

  • bastard_op3 hours ago
    I've been waiting 26 years for a Visio replacement since M$ bought it, hopefully they can do it too. No other app or web-based copies are good enough still (sorta omnigraffle if you use a mac [ew, no]), and I've tried most over the years to find one as I still use Visio weekly in 2026. It's the only reason I'll actually buy a copy of real windoze and visio for keeping around a VM, I can still buy real licenses overseas for both visio and project for ~$20usd each instead of the ~$500-1000usd actually IN the US.
  • nestorD5 hours ago
    My thinking is that cloning existing apps is missing the point. It still takes a disproportionate amount of time to get all of the functionalities and quirks of the original right. But, it takes no time to get the handful of things you need working, on your system. That is where I see the most potential: there is little need for massive pieces of software that do everything, I can build the components I need, customized for my use case, and move on.
    • Ekaros4 hours ago
      Does that actually work with Office tools? Like yes you can make your own documents and spreadsheets. But what about when you receive something from someone else? Or need to send it back after doing your edits? Do the files still work correctly?

      Big part of the value is in true interoperability...

      • zzril4 hours ago
        I don't think the best path towards interoperability is to run after those who based their entire business model on making interoperability a problem in the first place.

        If I were to create an office suite that cares for interoperability, it would be based on markdown and CSS, viewable in the terminal, one could `grep` and `sed` and `git diff` through it, LLMs could read and write it natively, ... But I'm afraid it'll take another 40 years until we're there.

  • 800xl6 hours ago

  • zzril4 hours ago
    This would be interesting if it was based on markdown and Jupyter notebooks and all that good stuff we have today. But just replicating what was useful some 37 years ago to get office workers accustomed to the new digital world? Why?

        A very small group of companies have the infrastructure required to train and serve a frontier model. They have a stranglehold on the compute/resources required for a new participant to break in.

        And an overwhelming majority of enterprises running AI in production do so via one of two providers.

          We'll like have an open-weight opus 5.5 class model we can run on (fancy) local hardware in a year or two at full perf, especially with AI optimized M7 macs. That's pretty distributed IMO.

    We are really speed running destroying the software market, the long term effects won’t be nice. There is a reason FLOSS isn’t about cloning 1-1 existing applications. That’s something we could always have done if we really wanted. What we will end up with will be corporations pushing everything to the cloud, pushing for even stricter copyright/trademark protections to fight against that type of clones, stricter controls over software distribution.

    Instead of using the power of LLMs to create genuine new products we instead get clone factories just to avoid paying or switch to an alternative. What a really dumb future we are building here, where trying to create novel software is a risk because any 14yo with a Claude subscription will clone it, distribute it for free. At least with keygen someone had to be pretty skillful and the distribution was niche…
