In theory you could also run this in a cloud. If they use TEE, then your data should remain private.
It is now (somewhat) possible to run fully local (no cloud, no spyware) Alexa/assistant alternative with Home Assistant, Ollama (I run it on Apple Silicon) and as an endpoint Home Assistant Voice Preview Edition.
I've written about my setup (and challenges), but TLDR: You can just say "Ok Nabu, turn on my bedroom AC" and it works.
I've dreamt about this in Cypherpunk Visions 2023-2025 (a short book). Now I am going to write update for 2026-2029 (3 years is a good timeframe) and this will be "normal" for those who want it now, it's not just a dream.

Yes.
But then I couldn't turn on the lights with my voice if internet is down. Not apocalypse ready.
I also run other apps such as nostr:npub1zjmlr0dyue8exympgh3xy2wyqm73kc8s7q2cua9rdaqvrl6aw9cs70r5gf so my home is vibing with intelligence.
