Cloud assistants vs. local AI: a privacy lens
A practical comparison of what typically leaves your home with cloud assistants, what local AI changes, and the questions worth asking before you invite AI into daily family life.
Most families do not read every privacy policy. They make a gut call: is this company worthy of hearing our home? Cloud assistants can be thoughtful products, and still move more data offsite than many families realize, because training, ranking, and abuse prevention often depend on signals collected at scale.
Local AI shifts the question. Instead of asking whether you trust this company with everything, you can ask what actually needs to leave, and when. The smaller that set, the easier it is to stand behind your choices with kids, guests, and your future self.
How they compare
Fully local, in your home.
Audio never leaves the device.
Stays on Hearth, never uploaded.
You control the hardware.
Full functionality on your local network.
Private, local, family-native.
Routines and lists only.
Routines and limited services.
What to look for in any system
Whether you choose Hearth or something else, these questions stay useful: Where does inference run? Where are transcripts stored? Can I delete my data without a support ticket? What happens if I unplug the device?
If the honest answers are clear and aligned with how you want to live, you are on solid ground. If they are buried or conditional, treat that as signal, not noise.
Why we bias toward local
We built Hearth because we wanted an assistant that could be excellent without treating the inside of your home as a data feed. Local-first is not a purity contest; it is a design constraint that keeps incentives closer to the people who use the product every day.
