Meet Jev: the AI that decides
You've seen Jev trend on X and LinkedIn, and apparently we're all supposed to know what that means already :)
Come and see it at work. I'll share my api key so you can test for free!
Yeah, it's that cheap ;)
Jev is not an LLM. But it's some form of AI, made by a company called TypeSafe.ai. It doesn't write text. You give it some data and a (formatted) question, it gives you a decision with a probability attached.
Things like:
"Does this profile match someone who has sold to Danish retailers?" (yes, 92%)
"Is this support email urgent?" (no, 81%)
"Which of these 12 categories does this invoice belong to?" (Travel, 64%)
Hundreds of questions in one call, in under a second, for a fraction of a cent.
The decisions you make by hand today, or pay a SaaS for, can live inside your own tools.
The program (~2 hours):
30 min live demo: what Jev is, a small demo app, then a real use case I've deployed in production
60 min guided practice: ask Jev your own questions, from Claude Code or from the demo app in your browser, with support
30 min discussion: what we found, where it fits in your tools, and where it breaks
📅 Save the date: 8 October 2026
⏰ Time: 16:30–18:30 - come 15 min in advance if you can ;)
🏛️ Location: Republikken, Vesterbrogade 26, 1620 Copenhagen V
👥 Capacity: 12 max. Small by design for quality support
💶 Cost: Free
What you'll walk away with:
A clear idea of what Jev is, and what it isn't
Your first questions answered by Jev, on your own test data
Ideas of where it would fit in your own tools
The demo code, if you want it
A rough idea of what it takes to put it in one of your own tools
This is for you if:
You're bringing AI into how your company works, or you do it for your clients
You've already used AI tools on real work, not just chatted with them
You want to see where it breaks, not just the demo
If you've never used an AI tool on real work, this may go too fast.
You must bring:
Your laptop (personal ideally)
Nice to have:
Claude Code installed: this could help you set up Jev. If not, the demo app in your browser does the job
A use case in mind, or find inspiration during the demo
