Developers Deeply Customize Apple Native Apps with Agents

Recently, several developers shared their practical experiences of deeply customizing and integrating Apple's native app ecosystem using AI agents. Rather than stuffing half-baked AI features into apps, they prefer maintaining the coherence of native experience and assembling automation capabilities on demand through agent workflows.

Confirmed

Preference for native apps: Developer @willccbb recently switched to Apple native apps like Reminders, iMessage, and Mail, finding the overall experience more coherent. He prefers customizing AI capabilities on demand via agent workflows and considers Apple's relatively conservative strategy reasonable.
LLMs writing scripts: Developer @xeophon noted that current large language models can already write AppleScript. By using an agent as a "chief of staff," they can smoothly drive native apps like Apple Calendar for deep automation workflows.
Calling internal APIs: Developers found ReminderKit to be hardcore, even able to access Apple's unpublished internal APIs. With this, @xeophon and @willccbb successfully transformed the system's Reminders into a dedicated "message board" or "kanban" for centrally managing, tracking, and interfacing with all their AI agent tasks.

Why it matters

This practice showcases a new approach for individual developers to find flexible AI automation paths within a closed ecosystem. It not only provides a lightweight alternative for multi-agent orchestration but also demonstrates the feasibility of using LLMs to cross system app barriers and achieve deep customization.
