AI agent tools and developer productivity

Contessa Intelligence Tech Limited (知繹智聯科技有限公司) is a software company focused on AI agent tools. We believe the real value of AI is not in a single model, but in helping people use whichever models they trust, on their own terms.

Our brand name ROUTOK comes from our motto, Reach Out Universal, Transfer Of Knowledge: connect every model and every tool, and let knowledge flow to the people who need it. In Chinese it reads 联通寰宇，绎知传智.

CodeFlux is our flagship product, a desktop agent that works directly inside your local projects.

ReachOutUniversalTransferOfKnowledge

Every letter of ROUTOK is a promise. Reach Out Universal means no model, vendor or deployment style should be out of reach. Transfer Of Knowledge means what an agent learns about your project should help you ship, not stay locked inside someone else's cloud.

CodeFlux: one agent, every model

CodeFlux is a local agent tool. It reads, edits and runs things in your own projects, and it talks to whichever model you point it at.

YOUR MACHINE → YOUR CHOICE OF MODEL

Local or remote models

Run a model deployed on your own machine or network, or call a hosted API. Use whichever fits the task, the budget and the privacy requirements.

Domestic and international vendors

Already adapted to the major model vendors in China and abroad, 50+ in total. A new vendor is a configuration away, not a software update.

Three fields to connect

Fill in the vendor's address, the model ID and your key. That is all it takes to bring a model into CodeFlux.

Multiple protocol formats

Different vendors speak different API dialects. CodeFlux supports several protocol formats, so you pick the one your vendor uses and keep going.

Install and use

No server to set up, no containers to run. Install the app, add a model and open a project.

Local-first by design

Project files, indexes and session history stay on your computer. With a local model, nothing has to leave your network at all.

// Principles

What we build by

01

Open to every model

We do not tie you to one vendor. Switch models whenever price, speed or quality changes.

02

Your data stays yours

Nothing is uploaded proactively. Context is sent only to the model you choose, and only when you use it.

03

Simple by default

A powerful tool should not need a manual to get started. The documentation is there for when you want more.

04

You stay in control

Plans can be reviewed, changes are shown as diffs, and every step can be undone.
