Luke: AI Companion & Journal

Luke is a lifelog that remembers your life, and keeps every bit of it on your iPhone.

Give Luke access to your photos and location, and it quietly builds a journal you never had to write: where you went, who you were with, what the day looked like. Ask about any of it in plain language, and Luke answers from your own memories, not from the internet.

JOURNAL • A timeline for every day, built from your photos and the places you visited • Add a note, a voice memo, or a mood in seconds • Month and year views to look back on any stretch of your life

MEMORIES • People: Luke recognizes faces on your iPhone and shows who you spend time with, as a ranking, a circle, or a connection graph • Places: your rhythm across home, work, and favorite spots, with the visit history of each • Timeline: month highlights, trips, and then-vs-now comparisons • Chats: import a LINE or WhatsApp chat and see your story with someone as charts and a portrait

TALK • Chat with Luke about your past: "When did I last see Priya?" "Where did we eat in Lisbon?" • Answers are grounded in your photos, places, and diary, with the photos to prove it • Call Luke and talk out loud, or record a dinner or a meeting; transcription and speaker recognition run on the phone • Runs a language model on the phone itself. Optional 3.4 GB download over Wi-Fi; nothing you say leaves the device

PRIVATE BY DESIGN • No account. No cloud. Photos, faces, locations, conversations, and diary never leave your iPhone • App Lock with Face ID, hide or delete people, export your data, back up and restore, or erase everything in one tap • Sharing anonymous usage statistics is off by default

LUKE PRO (optional subscription) Everything above is free, including voice calls and recorded conversations. On the free plan, text conversations and voice calls each have a daily limit; a call already in progress is never cut off, and both reset at midnight. Luke Pro removes the daily limits and adds Agent Access, so AI tools on your own computer can search your memories. $4.99 per month or $29.99 per year after a 7-day free trial. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings.
