The things you'd most want to ask an AI are the things you'd never want on someone else's server. So I built one that doesn't have a server.

CuriousLM runs the model on your own phone or laptop. Ask it why you keep apologising, paste in the message from your sister, let it read your calendar. It all stays on your device, encrypted. No account, nothing to sign up for, and it keeps working in airplane mode.

I'm Ebenezer, and this is the AI I wanted for myself.

A few things I'm proud of:

• Heat. Words arrive hot and cool to ink. The ones the model was unsure of stay underlined. Tap one to see what else it nearly said, and take the answer that way instead.

• It speaks first (Android). With your permission, source by source, it reads your notifications and calendar, then tells you who is waiting on a reply and what's due. Everything happens on your device, and nothing ever leaves it or goes to a server.

• Voice, Pocket Wikipedia and a journal, all on the device. Wikipedia's 121,797 most read articles fit in 60 MB, and answers cite them.

Honest limits: small models are slower and less clever than the giant ones in the cloud, and it's best on devices with 8 GB of RAM or more.

I'd love to know what you'd ask an AI if you knew nobody else could read it. And please tell me where it falls short.
