If you have no technical knowledge, you can use AI to code an app. You run it, and if it works, you've won. If you are not a lawyer, you can use AI to review/draft a contract. You sign it, and you have no idea if it works until you get sued and you win or lose in court.

Every contract tool can now tell you which contracts expire this year. The real test: "Extend A, B and C. Hold E and F." If E renews automatically, waiting is a decision to renew. A database field won't catch that. The contract will. open.substack.com/pub/arnaai…

Using/controlling other apps through your AI assistant of choice (Claude, ChatGPT, Gemini) is just a whole new experience. The future of all apps carries a unified interface.

AI can make mistakes. That's its most human feature.

How many agents do you think one would need to run what is considered a mid-size company today?

Turns out the next lawyer on the team might get paid in tuna. Our goal is the best AI agent for in-house legal. Europe-made open-source models are probably one of the ingredients.
Meet Mistral Large 4, aka Le Chonk. • 1T parameters, natively multimodal. 49B active. It is the best open weights model from US or Europe on aggregated benchmarks. • State-of-the-art on critical workloads, including cyber defense, manufacturing and finance and it surpasses closed frontier models on visual grounding. • Forged in Europe end-to-end and is deployable from Europe via our own Mistral Cloud infrastructure. • Available to all via API today. Working with cybersecurity partners privately. Open weights release end of October.

Should we have announced that we launched skills? And blueprints? 🤔@arna_ai So: Arna got skills. And Blueprints.

Should a corporate AI agent be a he, she, it or they?

In-house legal AI will succeed when someone from HR or Sales messages an AI agent about an issue, and the agent resolves it.

In the last ten years, there have been 31,000+ new US federal rules, and 20,000+ EU legal acts adopted (data from US Office of the Federal Register and EUR-Lex). We can play with the statistics - relevance of acts, state/member state acts, etc. But still - unexpected, huh?

How far is it going to go? Will there eventually be an iPhone 62?

Disappointed in Iceland's EU referendum outcome.

Omarchy might trigger a lot of curiosity and, in the end, create more demand for @ubuntu.

Y'all know I am a Eurofan, and I defend Europe against all non-Europeans mocking us. And while we do have our fair share of problems, one comment that makes me smile is: 'Europe is better at living than getting rich'. So I was surprised to see this as the headline of @drnovac's newsletter, which I love to read and have huge respect for him. I hope he responds to this post :) Dragos mentions that 'Europe is an extraordinarily good place if you are a salaried professional', but 'Try building a business instead, and the reality hits you in the face surprisingly early.' I've worked with tens, or probably hundreds, of CEE founders from cradle to exit, and many started in CEE and eventually moved to the USA. But it wasn't smooth sailing there either. Let me point out some clashes. Risk-taking: The environment impacts you, but that's in your head. The same European is more risk-averse in Europe than in the US. Just think differently. Find your circle of other great founders - there are many. Incorporating and fundraising in Germany is a bureaucratic nightmare. Indeed, instead use England (works great, cheap) or Cyprus if you want the EU (if Americans use DL, why can't we use CY?) Hiring? Start off with EOR (like @NativeTeams). Eventually, establish subsidiaries around Europe to run physical offices and hire locally. It's not difficult. You need an accountant for payroll and usually simple registration with the companies house. In the US? - Complicated tax filings in each state. In the EU? Single point of entry for VAT filings. Fundraising. There are so many great European VCs around these days, so go talk to them. And you have the big American names sitting in London. Europe has one huge benefit compared to all other parts of the world for young founders. Social cushion. You don't need much capital to kick off your business. AI, public infrastructure and services are all you need. Skip the strange public grants. I challenge everyone to name and describe an obstale to building in the EU, and I will serve you a practical solution.

Today, X is full of 'drop your startup name in this thread ' posts. I am deeply touched by everyone's generosity.

Slovenian growth comes from @rodpetrovic and me building @arna_ai
In 2026, many of Europe's economies are seeing faster growth than the US. Europe is making a comeback. 🇪🇺

X is a strange place. When I post something genuinely useful and value-creating about legal AI, I get two likes. When I make fun of differences between the US and the EU, I almost go viral.

There's a strong reason we should keep writing text ourselves instead of using AI. Writing makes you think. It forces you to read your thoughts and rethink them. Unless you are on X. Here, people write stuff without thinking at all.
