IdeaNote is a zero-stress idea capture and discovery tool. Capture flashes of inspiration in seconds, organize them effortlessly, and let AI help your scattered thoughts grow over time. Recording is never the end—let your inspiration continue to evolve. 【Core Features】 1、Lightning-Fast Capture: Deeply integrated with the iOS ecosystem. Trigger new notes instantly via Lock Screen widgets, Home Screen widgets, Siri shortcuts, or one-tap clipboard reading. Zero friction, so you never lose a fleeting thought. 2、3 Card Types & Color Tags: Automatically categorize upon creation using Idea, Info, or Task cards. Apply 6 customizable semantic colors to easily mark urgency and context without building complex folder hierarchies. 3、Inbox-Style Processing: Swipe right to archive, swipe left to trash. Separate the act of "collecting" from "processing." Jot things down now and organize them later, eliminating note-taking anxiety. 4、Idea Evolution: Link related cards to build a clear train of thought (e.g., source → derived). Watch your fragmented ideas organically grow into comprehensive projects. 5、AI-Powered Idea Memory: Our advanced AI analyzes your long-term notes to extract recurring themes, focus shifts, and deep insights, generating personalized "Memory Cards" that turn scattered data into real knowledge. 6、Serendipitous Review: Break free from linear reading. Our random flashcard carousel wakes up dormant ideas, giving old inspirations new value in your current context. 7、Multi-View & Visual Insights: Switch between Card, Grid, or Timeline views. Explore a beautiful Treemap heatmap of your topics, and receive automated Weekly Inspiration Reports to track your creative growth. 【Privacy First】 Your thoughts are strictly private. IdeaNote operates on a serverless architecture—all data is stored locally on your device by default. If you enable sync, your notes are securely routed only through your personal iCloud account. We cannot and will never access your data.
