Write me a short decline for tomorrow.
Sure: “Thanks for the invitation, unfortunately I can’t make it tomorrow. Let’s catch up soon!”
And all of this stays on my phone?
Yes, I run completely offline. Nothing is sent or stored.

Choose your AI
Both run entirely on your device. Choose what suits your phone.
JOLI is the larger model. Answers are more detailed and more accurate. In return it takes about 3.4 GB and wants a phone with some headroom.
JOLI Lite is the smaller model. It answers faster, takes only about 2.6 GB and also runs on older devices.
You can switch later or install the other one.
