Intelligent Diary is a 100% on-device private digital journal. It captures video, voice, photo, text, and scanned handwriting. Everything is transcribed and analyzed entirely on your device: the app learns who and what you talk about and how you felt about it, then turns years of entries into searchable text, insights, charts, and a map of your own words — without one byte ever leaving your phone. There's no account, no ads, no subscription, and no advice: it surfaces your own patterns and lets you draw your own conclusions. Your diary is a normal folder of ordinary files you can open, edit, and back up with any tool you like; it imports from Day One and Apple Journal, and syncs device-to-device over your own Wi-Fi — or through iCloud if you turn it on. The basics are free, and three one-time in-app purchases (each with a 60-day free trial) let you own everything forever.
