Eisenhower Matrix Task Prioritizer

Most to-do lists have a prioritisation problem: everything ends up on the same flat list, urgent noise drowns out important work, and the tasks that actually move the needle keep getting bumped by things that merely feel urgent. The Eisenhower Matrix splits that list across two axes — urgent versus not urgent, important versus not important — and the right action for each quadrant follows automatically.

Tasks you typed in a previous session are restored from localStorage the next time you open the tool, so your board persists across browser restarts without any account or sync service. Nothing is sent to a server.

What Each Quadrant Means in Practice

• Do First (Urgent + Important): a production outage, a deadline expiring today, a client waiting on a blocker. These get your attention now.
• Schedule (Not Urgent + Important): strategic work, learning, planning, relationships. Eisenhower argued these are the tasks most people neglect because they never feel urgent — block time for them or they disappear.
• Delegate (Urgent + Not Important): interruptions, most meetings, many emails. They demand a response but do not need your specific expertise. Hand them off or batch them.
• Eliminate (Not Urgent + Not Important): busywork, low-value habits, distractions you mistake for productivity. If a task lives here for more than a week, delete it. A task that never rises in urgency or importance was never worth doing.

Worked Example: Sorting a Day's Tasks

Type a task in any quadrant's input and press Enter or the + button. The task appears at the top of that quadrant's list immediately.

• Hover over any task to reveal the Move dropdown and a Delete button. The dropdown lets you re-categorise a task without retyping it — the non-obvious feature that first-time visitors most often miss.
• Each quadrant scrolls independently once it holds more than about six tasks, so the grid stays a fixed two-by-two even with a large backlog.
• The Clear all button asks for confirmation before wiping all four quadrants. Undo is not available after clearing.

How Big the Task List Can Get

• Tasks are written to localStorage under the key task-prioritizer-tasks on every change. Closing the tab or restarting the browser does not lose them.
• Private browsing windows do not persist localStorage across sessions in most browsers. Tasks added in a private window survive until the window is closed, then disappear.
• The browser's localStorage quota is typically 5 MB per origin. A plaintext task list would need roughly 50,000 tasks to approach that ceiling.
• Storage is scoped to the browser and device. Tasks are never synced to a server and are invisible to other devices or browsers.
