# Kortix vs Claude Cowork: a desktop assistant, or a company-wide agent platform?

Claude Cowork is the best agent on the desktop. But it runs one assistant per person, on Anthropic's models, with your data on their cloud. Here's where you outgrow it — and what an open, company-wide agent platform looks like.

Claude Cowork is, hands down, one of the best agents you can put on a desktop today. It inherits Claude Code's engine, genuinely does multi-step work across your files and apps, and has a clean approval model. So this isn't a "they're bad, we're good" post. The honest question is what happens when one person's desktop assistant has to become a whole company's way of working.

## What Claude Cowork is great at

- **It does the work, not just the talking** — give it a goal and it returns a finished deliverable.
- **A real permission model** — it shows a plan and waits for approval on consequential actions.
- **Extensible with plugins** — teach it how you like work done and expose your own tools.

## Where it stops: one assistant, one machine, one lab

- **One assistant per person** — not a fleet of agents running long jobs in parallel for the org.
- **Nothing is shared.** Each person’s agents, skills, and context live on their own desktop — what one person teaches, the company never gets.
- **Locked to Anthropic’s models** — no bring-your-own-key, so you pay frontier prices and can’t pick a cheaper model.
- **Closed and vendor-hosted** — you can’t self-host it, and your data flows to Anthropic’s cloud.

None of these are flaws for the product Cowork is. They’re exactly why it’s so good for one person — and exactly what you outgrow when "an agent on my laptop" needs to become "agents running our company."

## Shared across the company vs. siloed on a desktop

It’s not just the machine that’s landlocked — it’s the knowledge. In Cowork, each person’s agents, skills, and context stay on their own desktop. In Kortix, your agents, skills, and memory are **files in one shared repo**: what one person teaches, every teammate — and every agent — gets, and it compounds over time instead of resetting person by person.

## The model lock-in tax

Cowork only runs on Anthropic’s models, at Anthropic’s prices. Kortix lets you **bring your own key and run any model** — and the savings aren’t small. An open-weight model like **GLM-5.2** runs about **5–7× cheaper** than Claude Opus or GPT on output ($4.40 vs $25–30 per 1M tokens), and models like **DeepSeek** are **50×+ cheaper** on output. Route a cheap model for the bulk of the work and a frontier model only where it earns its keep.

> Same agents, [a fraction of the bill](/pricing) — and you can run them on your own infrastructure, even your own GPUs, with your data never leaving your walls.

## When to pick which

### Choose Claude Cowork if

you want a brilliant agent on one person’s desktop, you’re happy on Anthropic’s models, and you don’t need to self-host or run a fleet.

### Choose Kortix if

you want that same do-the-work power as a company platform — many agents [across departments](/enterprise), any model, self-hosted, with everything versioned and owned by you.

They can even coexist: a power user keeps Cowork on their desktop while the company runs its shared, governed workforce on Kortix.
