WebJevJev,
in the
browser.
WebJev is an AI agent that lives inside your browser. Jev — a model built for fast, structured decisions — reads the page, decides the next step, and the browser carries it out. No screenshots to re-read. No plan to re-invent at every click. Just the goal, and the work.
Goal: Find a flight from Zurich to London, under $200.

Decisions, at machine speed.
Execution, in the browser.
Most browser agents ask a large language model to look at the whole page and write out what to do next — slowly, and at full LLM cost, on every single step. WebJev works differently.
Fast decisions, not generation
Jev is a decision model, not a chat model. Given the page state and a goal, it returns a structured choice — which action, on which element — in a fraction of a second.
The browser does the work
The browser layer carries out the decision: click, type, select, scroll, navigate. The model never invents selectors or coordinates — it only picks from what is actually on the page.
Bounded, auditable actions
Every step is a constrained choice from the live page, so actions stay valid, repeatable, and easy to log. A language model is only called in when text actually needs to be written.
One loop, until the goal is done.
Observe
The browser reads the live page and lists the interactive elements that are actually available.
Decide
Jev chooses the next operation — click, type, select, scroll, or done — and the element it applies to.
Execute
The browser performs the action and the page updates.
Repeat
The loop runs again from the new page state until the goal is complete.
What we do
Astralumen LLC builds AI agent software and runs AI cloud services.
WebJev browser agent
Our browser agent, powered by Jev. It operates the web for you — research, forms, booking, data gathering — one fast decision at a time.
AI agent software
Custom AI agents and software development, including mobile apps — agents that operate software and the web on your behalf, built around fast decision models.
AI cloud services
Cloud infrastructure for AI workloads — compute, model APIs, and managed services that let teams run agents and AI applications without operating the underlying stack.
Astralumen LLC
Astralumen LLC is a software company based in Sheridan, Wyoming, USA. We build AI agent software and operate AI cloud services. Our focus is practical: agents that do real work — inside the browser, across applications, and on cloud infrastructure that stays out of the way.
WebJev is our browser agent. It is built on Jev, the fast decision model by TypeSafe AI, and it exists because we believe the useful part of an agent is not talking about the work — it is doing it.
