Most assistants meet you from scratch every time, while what you said sits on someone else’s servers under terms that can change. Here it is the other way round: conversations are encrypted before they leave your device, the key is yours, and storage is paid for upfront.
Not a difference in features, but in who owns what.
Content is encrypted before it leaves your device. What sits with us is an unreadable run of bytes — we physically cannot read it.
Not “recent messages”, but all of it: what you said six months ago and how it turned out. No re-briefing each time.
The permanent layer is paid for upfront and lives on a network no single company controls. If we are gone, it stays.
Switching language does not mean meeting a stranger.
The same memory is shared across all four. What was said in Chinese still counts when you ask in English.
Use whichever language you like, and switch mid-way. Memory holds the content, not the wording.
We do not convert to local currency on the page: showing one figure and charging another reads as deception.
