Summarise your invoices
"Which invoices from August are still unpaid?" ChatGPT reads the folder and answers in one sentence. Yellow is enough for that.
ChatGPT can now open and edit files on your computer. That saves a lot of copying and pasting. Kobel decides which folders ChatGPT may see and what it may do there, so everything else on your computer stays private.
Free basic version. No account, no cloud. Your files stay on your computer. Last checked: September 2026
When you connect ChatGPT to a folder, it usually gets everything inside it. It can read every file, change it and delete it. It cannot tell your project notes from your payroll. One misunderstood instruction is enough.
Kobel sits between ChatGPT and your files. You give every folder a colour, and ChatGPT gets exactly that. ChatGPT cannot open red folders, and anything you never add to Kobel does not exist for it. Every change is written to a log you can check later.
A few examples, and which colour the folder gets for each.
"Which invoices from August are still unpaid?" ChatGPT reads the folder and answers in one sentence. Yellow is enough for that.
ChatGPT fills your quote template with the customer's details. The template itself stays untouched, because the folder is orange.
Remove duplicate rows, sort columns, add totals. In a teal folder, Kobel keeps a backup first.
You mark tax, payroll and passwords red, so ChatGPT cannot open them. Or you never add them to Kobel at all, and ChatGPT does not even know they exist.
From the Microsoft Store or the Mac App Store. The basic version is free.
Drag a folder into Kobel and pick a colour. A good start is one project folder on "read only".
Open "Connect AI" in Kobel and choose ChatGPT. Kobel walks you through it one step at a time and shows when the connection is ready.
Every folder, program and account in Kobel has exactly one of these levels. You can change it with one click at any time.
You set your colours once. They apply to every AI app you connect to Kobel.
Kobel is a desktop app for Windows and macOS. There is no Kobel server that sees your files.
Access to connected apps is stored on your device, on Windows in the system's protected key store.
The activity log shows what the AI changed and what was blocked. If you want, it records every read as well. The AI itself cannot reach it.
No. The AI can neither read nor change the content of red folders. It can still see the name. If you want that gone too, simply do not add the folder to Kobel. Anything that is not in Kobel does not exist for the AI.
Kobel itself sends nothing to any server. When ChatGPT opens a file you allowed, that content becomes part of your chat, exactly as if you had pasted it. That is why the colours matter: they decide what can get there at all.
Yes, if the folder is teal. Kobel keeps a copy before every change, and a right click on "Restore original" brings back the state before the last change.
No. You drag in folders and pick colours. Connecting ChatGPT is guided step by step inside the app.
The basic version is free. Pro costs 49 euros once or 3.90 euros per month.
Install Kobel, drag in one folder, set it to "read only" and connect ChatGPT. It takes about two minutes and costs nothing.
