Three steps, then it runs without you.
Everything happens in plain language. If you can write a job description, you can run a Kybernos team.
01
Choose the roles
Pick from the gallery — support, sales, admin, research — or describe the job in one sentence.
02
Set goals and budget
A target to reach and a daily ceiling. You are warned before the cap, never after.
03
Let them run
They work together, get better each week, and call you when a decision is yours to make.
The cheapest option that still clears your bar wins.
Your team tests its own work against the standard you set, then picks where to send each task. You never choose a model — you choose a quality bar.

Questions people ask us first.
What is Kybernos?
An open-source AI workspace that installs on your computer, on top of DeepSeek Harness. You chat, work and code in it, and it plugs into the tools you already use. It is a suite of plugins (model catalog, skills, slide decks, agent teams…) that you switch on or off one by one.
Do I need to be technical to install it?
No. You download the installer for your system and run it, like any other software: no terminal. After that, you describe what you want in plain language.
How is it different from Claude or ChatGPT?
It isn't tied to any provider: you use the model of your choice, including a local one, with your own keys or your Claude Max and ChatGPT Plus/Pro subscriptions (through Claude Code and Codex). Its code is open: you can read it.
What is a Kyber?
A specialised agent: a role, a model, its own instructions and skills. Several Kybers form a team where one plans, others carry out the work and others review it. It is one of Kybernos's plugins, and you can leave it off.
Is Kybernos free?
Yes, the software is free and open source. What can cost money is using models: the Free plan to try it (slower), per-seat plans (see Pricing), or what you already pay your providers.
See pricing
Do my files go to the cloud?
Only what a task needs. That content (prompt, context) is sent to the provider of the model you chose, through our proxy, which logs only metadata (model, tokens, duration), never your prompts or outputs. Kybernos does not train any model on your content. Providers have different terms: some keep nothing, others keep data temporarily, some are outside Europe. The list is in the privacy policy.
