IdeaNook

IdeaNook is a fully on-device, private idea journal. AI can generate endless content—but your inspiration belongs only to you. Capture fleeting sparks and refine them into private silicon memory on your iPhone. Not lost in chat logs. Never uploaded to the cloud. ■ Chat-style capture When inspiration strikes, just send it. Type, snap a photo, or hold to record voice — everything flows into one idea stream, with full-screen image zoom. ■ Full-text search Lightning-fast local search with filters by text, type, and category. Keyword highlighting and tap-to-jump back to the original message. Works immediately after install — zero network, zero latency. ■ On-device AI (optional) When enabled, intelligence runs on your iPhone — no cloud API is ever called: · Auto-categorization into 10 smart categories: Work, Study, Life, Ideas, and more · Speech-to-text: hold to talk; transcripts are searchable and categorizable · Image understanding: on-device semantic descriptions for your photos · Digests: daily / weekly summaries, manual triggers, or long-press "summarize from here" ■ Privacy is the baseline No network permission. Data never leaves your phone. No account required. Photos write-only; microphone and camera on demand. AI is optional. Capture and search work perfectly without it. How to enable AI: · Apple Intelligence (recommended): no large model download on supported devices — Settings → AI Engine · Gemma offline path: agree to terms and download ~2.4 GB once in Settings Requires iOS 26.0 or later.
