Kilonotes vs Obsidian

Kilonotes is a handwriting notes app for students, combining note-taking with tools for turning lectures, PDFs, and recordings into study material. Its writing features include pressure sensitivity, palm rejection, and low-latency ink, with handwriting-to-text conversion that recognizes math equations. Users can import and annotate PDFs, then search handwriting across notebooks. Kilonotes AI can explain notes, create practice questions and flashcards, summarize documents, and generate mind maps. The app can record and transcribe audio, then produce summaries and key points. Core note-taking works offline; AI tasks wait for a connection if the device is offline. The Free plan includes five notebooks and basic AI, with trial uses of AI features before AI credits are needed. Premium adds unlimited notebooks, full AI, custom fonts, page styles, and other advanced features. The maker’s plans page does not show paid prices, though App Store listings show selected plan prices. The app is listed for iOS and Android, with Android 12 or later required on Android.
