Learn anything, offline — on your iPad or iPhone. Starting with code. KaView's vision is a universal library you learn from offline. Today it teaches you to program from real projects: structured courses, hands-on practice in a real codebase, and an AI tutor that explains any line. It opens with Mastering Believe — Kalira's free reference curriculum (MIT-licensed): markdown lessons paired with runnable code, on agents, neural networks, algorithms, system design, and the craft of learning. Or open any GitHub project and study it like a book. No autoplay. No ads. No algorithm pulling you elsewhere. Just a real codebase and the quiet tools to understand it. LEARN, YOUR WAY, OFFLINE • Mastering Believe ships with the app, and five curated collections are ready on first launch — gentle starter paths, fully yours to edit: - First steps in Python - Understanding AI agents - Build an LLM from scratch - A tour of Swift - Essential algorithms • A dedicated Cours tab: one tap downloads a course to read • Go further: a marketplace of public repos by theme — AI, Python, Swift, web, books AN AI TUTOR THAT READS THE PAGE • Ask in plain words — "explain this like I'm new," "what does this term mean," "why is it written this way" • Tap any snippet for Explain, Complete, or Refactor • On-device when Apple Intelligence is on (iOS 26+): private, no connection needed • Or bring your own OpenAI or Anthropic key READ CODE LIKE A BOOK • Markdown and source side by side, syntax-highlighted • Progress is local to the module or folder you are in — n of total for that chapter, not hundreds of pages across a whole repo • Book-style chrome: aligned prev/next arrows, ⋯ menu beside next, large tap targets • Navigate sheet puts lessons first; exercises are listed separately • Changing chapter scrolls you back to the top • Dozens of languages, rendered cleanly PRACTICE IN A REAL EDITOR • Fix a typo, jot a note, save a TODO as you learn • Sign in with GitHub, clone, edit, commit, push — without leaving the app • Token stays in the iOS Keychain BUILT FOR iPHONE AND iPAD • Native iOS 26 design: Files, Page, Cours, Chat • iPad: three-column layout, Split View, Stage Manager • Dynamic Type, VoiceOver, hardware keyboards, VS Code–style shortcuts PRIVACY BY DESIGN • No analytics, no trackers, no ads, no telemetry, no account • Data Not Collected KaView is a place to learn — a reader, a light editor, and an AI tutor, not an IDE. It doesn't run code. iOS 18 minimum; the on-device tutor needs iOS 26+ with Apple Intelligence. Open a course. Ask a question. Understand the code.
