Kapsula App

Kapsula turns a single HTML file into a real app on your phone. Paste code from an AI chat, drop an .html file, or point to a URL — Kapsula runs it in a sandbox and gives it native powers through a tiny JavaScript bridge: • Exact alarms — real system notifications that fire to the second, even when the app is closed • Notifications with sound and vibration • Local storage that survives restarts • Haptics and a simple sound player Why Kapsula instead of a browser tab: • Alarms actually fire. A tab can't wake your phone at 10:33 sharp — a scheduled system notification can. • Your project lives on the home screen of the app, not lost among tabs. • No account, no cloud, no analytics, no tracking. Your code and your data stay on your device. • File and pasted-code projects work fully offline; the internet is used only for URL projects. Made for people who build small personal tools with AI: shift planners, tea timers, checklists, reminders, tiny games — anything a chat can write into one HTML file, Kapsula runs like an app. The same file works in a desktop browser too: the kapsula.* bridge is optional, so you can develop on your computer and run on your phone. Kapsula executes only the code you add yourself. It is not a web browser: there is no address bar, no search, no navigation — just your projects.
