Nyx is a dream journal for people who keep coming back to their dreams. Some dreams return. Others change in ways you only notice when you read them together. Write or record an entry, explore a reflection, and ask what connects it to earlier nights. Your own words stay at the center. FIND CONNECTIONS ACROSS YOUR DREAMS Once you have saved at least three dreams, ask questions across your journal. What changes when water appears? How do the places in recent dreams compare with earlier ones? Nyx uses AI to compare selected excerpts, pointing out similarities and differences. Dated quotations link back to the original entries so you can read the context yourself. Reopen saved answers without asking the same question again. CAPTURE THE DREAM WHILE IT IS FRESH - Write a few words or a longer entry - Record your voice and turn it into text - Use the low-light night recording screen when you wake in the dark - Add emotions, tags, vividness and lucid-dream details - Choose an optional illustration for your entry PERSONAL DREAM INTERPRETATION Explore eight reflection perspectives, including symbolic, psychological, personal-growth and memory-and-sleep approaches. Read the complete reflection, ask a follow-up about that dream, and save your own takeaway beside the original entry. These are suggestions for personal reflection. AI can be mistaken, and you decide what fits your experience. BUILD A DREAM DIARY YOU CAN RETURN TO Browse your dreams by date, search your words and revisit earlier entries. Optional reminders help you make space for a morning note. Over time, your journal gives you more context for questions about recurring places, emotions and experiences. START WITH YOUR JOURNAL Writing, recording, reading and exporting your dreams are free. Sample three full AI reflections and two questions across your journal, without a card or expiry. Optional monthly or yearly membership provides ongoing AI reflections and archive questions. Available plans and localized prices appear before purchase. Your saved entries and completed results remain available without a subscription. KEEP YOUR WORDS WITH YOU Saved entries sync to your account. AI reflections and voice transcription use online services. Lock the app with a PIN or supported device biometrics, export your cloud journal as PDF or JSON, and delete your account from Settings. Exports include your written entries, full reflections, saved dream conversations and completed archive answers. Device-local drafts and audio are separate from the cloud journal export.
