Read full description

Nabu is a daily companion for couples who want to understand each other better — one honest question at a time. Every day, Nabu asks you and your partner a new question about how you think, feel, and see your relationship. Answer at your own pace, then reveal your answers together and discover where you align, where you differ, and what's worth talking about. WHAT YOU'LL FIND IN NABU Daily Questions — A new thoughtful question each day, covering everything from playful "this or that" picks to deeper reflections on love, communication, and connection. Partner Reveal — Link up with your partner and compare answers side by side. See what you have in common, spot the surprises, and use them as a starting point for real conversation. A 25-Question Deep Dive — Take Nabu's longer quiz whenever you're ready — pause and resume anytime — for a fuller picture of how you approach your relationship. AI Reflections (optional) — With your explicit, separate consent, Nabu can generate personalized insights from your answers and offer a chat companion to talk things through. You're always in control — turn AI reflections on or off anytime in Settings, and nothing is sent until you say yes. Your Progress — Build a streak, revisit past answers, and watch your self-understanding grow over time. PRIVATE BY DESIGN Nabu doesn't record audio, track your location, or read your contacts, photos, or calendar. Your answers are yours, and you can request their erasure at any time. AI processing of your content requires a separate, explicit, and fully withdrawable consent, kept apart from the basic terms you agree to when you sign up. A NOTE ON WHAT NABU IS Nabu is a self-reflection and communication tool for couples. It's not a medical or clinical service and isn't a substitute for professional support — it's a space to notice patterns, spark honest conversation, and grow closer, one question at a time. Whether you're newly together or years in, Nabu gives you and your partner a simple daily ritual for staying curious about each other. Download Nabu and start today's question.
