in that regard every text editor or any software that just CRUDs files locally would be local-first and the term would be meaningless
local-first means that it does not need internet-access to work and use the app and synchronization comes later, when there's time and internet access. please read up on this.
edit: i originally wrote "local-first means that it does need internet-access to work and use the app...", which is bullshit and also doesn't make sense in the context. i added the "not" so it is clear.
