Meridian pairs Apple Intelligence with one idea: processing one event deeply is more powerful than recording everything, and it does it entirely on your device. PRIVATE BY DESIGN, POWERED BY APPLE INTELLIGENCE Your prompts are personalised by Apple's on-device Apple Intelligence (soon: Apple's Private Cloud Compute), not a generic script, always shaped by what you actually wrote. And it stays private: your words are never stored on a server we control, or seen by anyone but you, including us. There's no account to create and nothing to sync. You describe a single thing that happened, big or small, recent or long past. Meridian builds a personalised seven-day reflection journey around it, inspired by principles from Acceptance and Commitment (ACT) and Cognitive Behavioural (CBT). One prompt a day. One day a day. No streaks to keep, no feed to scroll, nothing to perform for anyone else. HOW IT WORKS — Day 1: Witness the moment from a little distance, rather than reliving it. — Day 2: Name what you're feeling, without judging it. — Day 3: Examine the story you've told yourself about what happened. — Day 4: Acknowledge what you needed, and what that reveals about what matters to you. — Day 5: Reframe — find another reading that's equally true and less heavy to carry. — Day 6: Separate what's in your control from what isn't. — Day 7: Integrate what the week has asked of you, then choose how to close it. On the seventh day, you choose one final piece to read: The Mirror, a reflection on your week, or The Letter, a warm note from the calmer version of yourself that emerged through the writing. Read it once. Then, when you're ready, release it, every word of the journey is permanently deleted from your device. What mattered stays with you; the record doesn't have to. A NOTE ON CARE Meridian is a space for everyday reflection, the ordinary weight of grief, conflict, disappointment, and change. It is not therapy, and it is not a substitute for professional mental health care. It isn't designed for working through severe trauma or abuse. If you're going through something heavy, please consider reaching out to a mental health professional or a local support service — reaching for real support is always the stronger choice. Meridian asks for one thing at a time, and gives it the attention it deserves.
