About this release
ChatGPT Classic is the desktop build of the assistant rather than a browser tab, and the difference is in how it sits on the machine. It docks to a corner, answers a global hotkey, and keeps a persistent conversation history on disk so a thread you started in the morning is still there in the afternoon. For anyone who was living in a pinned browser tab, moving to the native client removes a lot of small friction.
The part people notice first is the companion window. Point it at an open application, hand it a screenshot, or drop a file into the chat and it reads the contents into context, so a question about a spreadsheet, an error dialog or a page of a document does not need a paste. Attachments are handled in the chat, images and documents alike, and the response lands as ordinary selectable text you can copy straight back out.
Everything else is the assistant model set you already know, wrapped so it feels like a real application. Named conversations, pinned threads, a searchable history, per conversation instructions, and export of a thread to plain text or markdown. The build here is the complete signed client with the interface unlocked from first launch, so nothing is gated behind a sign in state after setup.

Installation notes
Follow these in order. Most reports of a failed install come from skipping a step rather than from the package itself.
- Close any browser based session before you begin.
- Disconnect from the network for the length of the install.
- Extract the archive to any folder you like, the package is small.
- Run the installer as administrator and finish the wizard.
- Launch once so the local profile is created, then close it.
- Reconnect to the network.

Things worth knowing

Can it read an open application?
Does the hotkey work everywhere?
What people are saying
The hotkey plus companion window is the whole reason to switch off the browser tab. Point it at a window, ask, done.
History search actually finds things inside long threads now. That was the thing that annoyed me before.
Runs fine offline for the local interface. Firewalled it and it behaves.
