Architecture

Not a wrapper. Here's what Yesper actually looks like.

A chat wrapper has one model and one text field. Yesper is a production system of specialist agents, Swedish authority data, document pipelines, and long-lived project memory — coordinated by an orchestrator that decides who does what for every request.

The assumption

A chat shell

LLM One prompt. One answer. No memory. No tools. No data.

One model. One text box. Forgets you the moment you close the tab.

Yesper — in reality

A production AI system for construction and bid work

Your team works in a project workspace

Orchestrator agent
Routes, delegates, and assembles results from many specialists
Not a single LLM that answers. A control plane that chooses the right tools, runs them in parallel, returns the results to the loop, and knows when it's done.
A fleet of specialist agents — 30+ and growing
