By mult-idevice (mobile, tablets, desktop) I guess we cover cross-platform but the idea is to run on any device/platform with access to whatsapp with one session running as the "server" (the desktop one). This server is the user of an whatsapp number (connected using wa-js) and also connected to a LLM of choice.
The current use-case is the most basic possible, I'm using it to keep a daily, notes and ask general questions. the LLM then save some of the data it extract from the notes into collections that I plan to use later. It is quite new project yet
