Reassign

Product Introduction

1. Definition: Reassign is a SaaS-based circular day planner and productivity platform. Technically, it is a visual time-blocking application that uses a radial (dial) interface to represent a 24-hour period, integrated with a two-way sync engine for external tools and an AI agent system via the Model Context Protocol (MCP).
2. Core Value Proposition: It exists to provide busy knowledge workers and makers with a holistic, visual planning system that unifies disparate calendars and task managers into a single, malleable daily plan. Its primary value is enabling dynamic, intuitive daily planning that mirrors the non-linear nature of a busy life, with AI-assisted rescheduling.

Main Features

1. The Circular Day Dial: The core interface is a 24-hour radial timeline with midnight at the top and noon at the bottom. Users interact by dragging to create time blocks, which can be moved, resized, or reshaped directly on the dial. The visualization uses color-coding for life areas (work, family, side project, personal) and fill patterns to indicate energy expenditure (recharge, flow, grind, drain), providing immediate visual context for the day's composition.
2. Universal Two-Way Synchronization: The platform features a robust sync engine that maintains bidirectional integration with popular productivity ecosystems. This includes Google Calendar, Microsoft Outlook (for events), and task managers like Todoist, Microsoft To Do, Google Tasks, Linear, and TickTick (Pro feature). Edits made on the Reassign dial propagate back to the source calendar or task, and incoming items from these sources appear as editable blocks on the dial.
3. AI Planning via Model Context Protocol (MCP): A Pro feature that allows AI assistants (like Claude or ChatGPT) to read and edit a user's Reassign plan directly. Through the MCP standard, the AI can execute complex rescheduling, time blocking, and task prioritization by making the same API calls a user would, enabling live, AI-driven restructuring of an afternoon or entire day based on a natural language brain dump or command.

Problems Solved

1. Pain Point: Fragmented planning across multiple linear calendars and to-do lists leads to cognitive overload, poor time visibility, and difficulty adapting when plans inevitably change. Traditional planners lack a holistic, at-a-glance view of energy allocation across life domains.
2. Target Audience: The primary persona is the "busy maker": professionals (often developers, designers, founders) juggling a demanding day job, family commitments, and a creative side project or business. Secondary audiences include any knowledge worker, project manager, or freelancer seeking a unified, visual approach to daily time management.
3. Use Cases: Essential for visually planning a day that mixes meetings (from Google Calendar), deep work tasks (from Linear), personal errands (from Todoist), and family time in one view. Critical for rapid daily replanning when a work meeting runs over, allowing the user to drag blocks or use AI to reshuffle the remaining hours. Vital for energy-aware scheduling, ensuring draining tasks are balanced with recharging activities.

Unique Advantages

1. Differentiation: Unlike linear calendar apps (Google Calendar, Outlook) or list-based task managers (Todoist), Reassign provides a spatially intuitive, radial overview of the entire day. Unlike other time-blocking apps, its core innovation is the circular interface combined with true two-way sync across major platforms and native AI agent control, creating a centralized command center for the day.
2. Key Innovation: The radial timeline interface itself is the primary UX innovation, transforming abstract time into a tangible, manipulable shape. The technical integration of the Model Context Protocol (MCP) for AI control is a secondary innovation, moving beyond simple chat-based AI to grant AI agents direct, structured editorial control over the planning canvas, mirroring human actions.

Frequently Asked Questions (FAQ)

1. What is Reassign.ai and how does the circular planner work? Reassign.ai is a visual productivity platform that uses a circular day planner (or dial) for time blocking. It works by letting you drag and drop blocks of time on a 24-hour clock face, color-code them by life area, and sync changes bidirectionally with your existing calendars and task apps like Google Calendar and Todoist.
2. How does Reassign AI integration with ChatGPT or Claude actually function? Reassign's AI integration uses the Model Context Protocol (MCP), allowing AI assistants like Claude Desktop or compatible ChatGPT clients to securely read your plan and execute edits. You can give a natural language command (e.g., "brainstorm my afternoon"), and the AI will directly manipulate the time blocks on your dial to reorganize your schedule.
3. Is Reassign a free day planner app, and what does the Pro subscription include? Reassign has moved to a required subscription model. A free trial is available for new users. The Pro plan ($14/month or $120/year) unlocks all features, including two-way sync with all connected apps (Google Calendar, Outlook, Todoist, Linear, etc.), AI planning via MCP, and access to list and timeline views alongside the main dial.
4. Can Reassign sync with both Google Calendar and Microsoft Outlook simultaneously? Yes, Reassign Pro supports simultaneous two-way synchronization with multiple calendar and task sources. You can connect both Google Calendar and Microsoft Outlook, along with tools like Linear and Todoist, to have all events and tasks appear as unified, editable blocks on your single circular day planner.
5. What happens to my data if I cancel my Reassign Pro subscription? According to their policy, your planning data remains stored in your account if you cancel. However, to actively use the planner—to view, edit, or sync your dial—you will need an active Pro subscription. Your synced data from external services is not deleted.
