Make time visible. Make every day count.
让时间可见，让每一天都有意义。

Deadliner (Deadliner 待办日历) is a family of time-management applications that brings tasks, schedules, habits, and AI assistance into one focused workspace. We build native experiences for every platform while sharing the business capabilities that should remain consistent.

Deadliner（Deadliner 待办日历）是一组时间管理应用，将待办、日程、习惯与 AI 助手整合在一个专注的工作空间中。我们为各个平台打造原生体验，同时共享应保持一致的业务能力。

DeadlinerStudio is maintained by mobile developer Aritx Zhou, desktop developer XiaoChennnng, and product manager qiao411.

目前，DeadlinerStudio 由移动端开发 Aritx Zhou、PC 端开发 XiaoChennnng 与产品经理 qiao411 共同维护。

The mobile architecture keeps UI native, while ViewModels and business capabilities are shared with Kotlin Multiplatform (KMP). The KMP business layer uses expect / actual contracts to work with platform-native implementations, and integrates with its own persistence and networking infrastructure through SQLDelight and Ktor. AI capabilities are accessed through open interfaces; the implementation lives in the closed-source com.deadliner.lifi framework.

移动端架构保留各平台原生 UI，同时通过 Kotlin Multiplatform（KMP）共享 ViewModel 与业务能力。KMP 共享业务层通过 expect / actual 契约与平台原生业务实现交互；内部则使用 SQLDelight 与 Ktor 对接持久化和网络基础能力。AI 能力通过开源接口访问，具体实现位于闭源的 com.deadliner.lifi 框架中。

Lifi also includes a planned KotlinRPC server bootstrap. Together with the Go-based Deadliner Server product, it will form the service-side architecture.

Lifi 还包含一个待规划的 KotlinRPC 服务器 bootstrap；它将与 Go 实现的 Deadliner Server 产品共同构成服务端架构。
