A private place to say what's on your mind. Just Nod is a calm AI you can talk to about anything: a long day, something you can't stop thinking about, or whatever's on your mind. It listens, replies in a warm, unhurried way, and asks the kind of question that helps you keep going. Everything stays on your iPhone. — NO SIGN-UP No account, no email, no password. Open the app and start typing. Not sure where to begin? Tap a suggestion like "Something's on my mind." — STAYS ON YOUR PHONE Your conversation is saved on your iPhone and answered by AI that runs on your iPhone. It isn't sent to us or anyone else. No ads, no tracking. — WORKS OFFLINE On a plane, in a tunnel, with the Wi-Fi off. Nod doesn't need the internet to reply. — REMEMBERS WHAT MATTERS As you talk, Nod keeps short notes about what's been going on, so you don't have to repeat yourself. You can read every note, forget any of them, or start fresh and clear everything. — OR JUST TALK Tap the mic and say it out loud. Your words appear as text you can check before sending, and your voice is turned into text on your iPhone. — YOUR WAY Choose shorter or longer replies, and whether Nod mostly listens, reflects back, or offers a little perspective. Add a line about yourself and Nod keeps it in mind. — LOCKED WITH FACE ID Turn on Face ID and only you can open it. Not a partner glancing at your phone, not a friend passing it around. — LIGHT AND DARK A warm, simple design that follows your iPhone's appearance, or pick light or dark yourself. — OPEN SOURCE All of Nod's code is public, so anyone can check it works the way we say. WHAT YOU NEED iOS 26 or later. On iPhones with Apple Intelligence, Nod works right away. Other iPhones with at least 6 GB of memory (such as iPhone 13 Pro, iPhone 14 and newer) download Nod's own AI once, about 2–3 GB over Wi-Fi. Just Nod is for everyday conversation and doesn't give professional advice. Made by Speculative Dynamics.
