Private AI assistants
13 apps, each with a privacy passport
A hosted assistant has to read your prompt to answer it, so look at what happens around that: whether chats are stored, whether history is encrypted so only you can open it, and whether your words train future models. Confer, Maple and Tinfoil process prompts inside sealed hardware, Lumo encrypts saved history, and Duck.ai and Brave Leo keep history on your device.
