Side Reminder

Product Introduction

1. Definition: Side Reminder is a native macOS productivity utility and specialized client for the Apple Reminders ecosystem. Built using the SwiftUI framework, it functions as a persistent sidebar overlay that utilizes edge-activation triggers to provide immediate access to task lists without traditional application switching (Cmd+Tab). It is technically classified as a workflow optimization tool and a desktop enhancement utility for macOS 14 Sonoma and later.

2. Core Value Proposition: Side Reminder exists to eliminate "context switching friction" for power users. By integrating directly with the native Apple Reminders database via iCloud, it allows users to manage tasks, execute AI-driven automation, and track focus sessions while remaining within their primary workspace (e.g., IDEs, design tools, or browsers). Its primary value lies in its combination of "frictionless capture" and "AI-assisted execution," bridging the gap between simple to-do lists and complex project management workflows.

Main Features

1. Edge-Triggered Smart Panel: The core interface remains hidden at the screen's periphery until the cursor moves to the designated edge. Utilizing a smart delay algorithm to prevent accidental triggers, the panel slides in to provide full access to iCloud-synced lists. It employs a "hover-to-show, move-away-to-hide" logic, ensuring that task visibility never compromises screen real estate or breaks the user's focus on their primary application.

2. On-Device AI Voice Input: Users can invoke a voice-to-task feature via the Cmd+Shift+V shortcut. Unlike cloud-dependent assistants, Side Reminder utilizes on-device AI for speech recognition and natural language processing. This ensures zero latency and total data privacy, as the audio never leaves the local hardware. It allows for the rapid capture of reminders with due dates and priorities using natural speech patterns.

3. Automatic Kanban Board Conversion: Side Reminder dynamically transforms standard Apple Reminders lists into visual Kanban boards. By parsing list "Sections" (a native Apple Reminders feature), the app generates columns such as "Backlog," "In Progress," and "Done." This provides a Trello-like project management experience using native Apple data, supporting drag-and-drop task movement and automated completion workflows.

4. Developer-First CLI and AI Agent Integration: The app includes a proprietary CLI tool (sidereminder) that communicates with the main application via Unix socket IPC (Inter-Process Communication). This allows developers to add, list, and complete tasks directly from the terminal. Furthermore, it features deep integration with AI agents like Claude Code, enabling users to right-click a task to launch an automated AI session that executes the task within a built-in terminal.

5. Integrated Focus Timer and Media Previews: Side Reminder includes a floating focus timer that can be detached from the sidebar to remain on top of all windows. Additionally, it features rich link metadata parsing, allowing YouTube videos or technical documentation links to be viewed or played within the reminder interface, preventing the need to launch a full web browser.

Problems Solved

1. Context Switching and Flow Interruption: Frequent app-switching to check to-do lists leads to cognitive load and decreased productivity. Side Reminder solves this by making the list a transient layer of the desktop environment, keeping the "Backlog" visible without it being intrusive.

2. The "Data Silo" Problem: Many third-party task managers require users to migrate away from the Apple ecosystem. Side Reminder solves this by acting as a "Pro UI" for the native Apple Reminders app, ensuring that all data remains synced across iPhone, iPad, and Apple Watch via iCloud while providing advanced desktop features.

3. Target Audience:

• Software Developers: Who need to track bugs and PRs without leaving their IDE or terminal.
• Designers: Who require quick access to feedback notes while working in full-screen applications like Figma or Adobe Creative Suite.
• GTD (Getting Things Done) Practitioners: Who need a "capture" tool that is always one gesture away.
• Privacy-Conscious Professionals: Who require AI features but cannot use cloud-based processing for sensitive task data.

4. Use Cases: A developer adding a "Fix login bug" task via CLI during a terminal session; a student recording a lecture note via voice while keeping a PDF open; a project manager dragging tasks across Kanban columns to update a team-shared iCloud list.

Unique Advantages

1. Differentiation: Unlike traditional task managers that operate as standalone windows (e.g., Todoist, Things 3), Side Reminder is an "environmental" utility. It doesn't compete for window space; it augments the screen edge. Compared to the stock Apple Reminders app, it adds developer-centric features like the CLI and AI execution terminal that are absent from the macOS default.

2. Key Innovation: The "Right-click to AI Agent" handoff is a significant innovation. By passing the task context (title, notes, and list) directly to Claude Code or other CLI-based AI agents, the app transitions from a simple list-maker to a task-executor, significantly reducing the "time to start" for technical work.

Frequently Asked Questions (FAQ)

1. Is Side Reminder a replacement for the Apple Reminders app? No, it is a powerful companion app. It uses the same database as the native Reminders app via the EventKit framework. Any task added or edited in Side Reminder will instantly reflect in the official Apple Reminders app on your Mac, iPhone, and iPad.

2. How does the AI agent integration work with Claude Code? Side Reminder provides a built-in terminal environment and a CLI bridge. When you select "Get Things Done with AI," the app passes the task description as a prompt to the configured AI agent. The agent then runs within the Side Reminder sidebar, allowing you to watch the AI perform terminal commands, edit files, or run tests in real-time.

3. Does Side Reminder collect any personal data? Side Reminder is designed with a "zero-knowledge" architecture. It has no user accounts and no central servers. All task data is stored in your private iCloud account managed by Apple, and all AI voice processing happens locally on your Mac’s silicon (M1/M2/M3 chips) using macOS native speech APIs.

4. Can I use the Kanban view for all my lists? Yes. Any list in Apple Reminders that contains "Sections" will automatically be rendered as a Kanban board in Side Reminder. You can customize these sections within the app or in the native Reminders app to suit your specific workflow, such as "To Do," "Doing," and "Done."
