ChatGPT Desktop
Same account.One window per folder.
Ritemark runs ChatGPT with the account you already have. The difference is the window: in Ritemark it belongs to one folder, and everything in it comes from that folder.
ChatGPT Desktop is the better all-round assistant. This page is about documents that live in your folders.


Each folder gets its own window.
⌥-click a project on Home (Alt-click on Windows) to open it in a window of its own. That window lists only the conversations saved in its folder, so one client's conversations stay out of another client's window.

ChatGPT and Claude on the same document.
Address a margin comment to @claude, or to @codex for ChatGPT, and it goes to that agent. You pick the agent for every conversation.
