Jianzhi AI
An AI workspace that does the work
Give Jz Desk a task and it gets on with it: reads what is in your folder, looks things up, writes the document, works through the numbers, and shows you what it changed. Sign in with your own ChatGPT account; nothing goes through us.
You bring the model account. Sign in with ChatGPT and you are done — or use an OpenAI API key, through a relay if you need one.
Get it working
Jz Desk ships without a model account of its own, so it signs in with yours. Three steps, the same on macOS and Windows.
- Step 1
Download and install
Get the build for your computer from the download page. Everything is inside the app, so there is nothing else to install.
macOS — Open the .dmg, drag Jz Desk into Applications, then open it from Applications.
Windows — Run the installer. It is not code-signed yet, so Windows may say it protected your PC: click More info, then Run anyway. Open Jz Desk from the Start menu when it finishes.
- Step 2
Sign in with ChatGPT
On first launch, Jz Desk asks you to connect an account. Click “Login with your ChatGPT account”: your browser opens OpenAI’s sign-in page, and once you have signed in there, Jz Desk finishes signing in by itself. Usage counts against your ChatGPT plan; there is no API key to create.
- Step 3
Pick a folder and ask
Choose a folder for Jz Desk to work in and give it something to do — a question about what is there is enough. A reply means you are set up.
What you get
It works on your real files
Point it at a folder and it reads, writes, and tidies what is there — documents, notes, spreadsheets, images, code. Every change it makes is shown to you, not buried.
One assistant, many kinds of work
Turn meeting notes into a summary, compare two drafts, rename a folder of files, total up a CSV, research a topic on the web, fix a script. Ask in plain language.
Your account, nothing in between
Jz Desk talks to OpenAI directly, signed in as you — with your ChatGPT account, or an API key you control. No middleman, no per-seat pricing, nothing to sign up for here.
It asks before it acts
Actions run in a sandbox, and anything that touches the network or files outside the folder you gave it asks for approval first. You set how much rope it gets.
One download, quick from anywhere
Everything ships inside the app, served from our own servers — quick from mainland China. Open it and sign in; no terminal, no app store, no package manager.
You can see what it uses
The Usage page tallies tokens and estimated cost per run, so a long session never surprises you on your plan's limits or your provider's invoice.
Questions
- What does it cost?
- The app is free. What the model uses comes out of your own account — your ChatGPT plan when you sign in with ChatGPT, your API bill when you use a key. Jz Desk never sits between you and that. The Usage page shows a per-run breakdown.
- Which platforms are supported?
- macOS (Apple Silicon and Intel) and Windows x64. Linux is not supported yet.
- Do my files leave my machine?
- Only what Jz Desk sends as context for the task you asked for, and it goes straight to OpenAI, or to the relay you configured. We never see it. Everything else runs locally.
- Is this related to Codex?
- Yes. Jz Desk is built on OpenAI's open source Codex agent core (Apache-2.0), with a desktop app of our own. It signs in to your own OpenAI account; no model traffic goes through Jianzhi AI.
