About Kosshi

Kosshi is a native outliner application designed for macOS and iOS, offering a fast and responsive experience for organizing thoughts, notes, and tasks in a hierarchical structure. Built on Apple frameworks, it prioritizes performance, allowing users to manage large outlines with tens of thousands of rows without sacrificing speed or responsiveness. The application supports features like zooming into specific rows, rich text formatting with Markdown, and embedding images and files directly within outlines. Kosshi is ideal for individuals who need a robust tool for structured thinking, project planning, note-taking, and task management. Its deep integration with Apple's ecosystem, including iCloud for sync and Apple Reminders/Calendar for date-based tasks, makes it particularly suitable for Apple users. The pay-once model and local data storage with iCloud sync emphasize user privacy and a commitment to a subscription-free experience.
