Build a unified productivity app with V0 using Next.js, Supabase, and Clerk that combines tasks, notes, a Pomodoro timer, and daily planning in one workspace. Features drag-and-drop kanban, global search via Command palette, and optimistic UI updates — all in about 1-2 hours.
What you're building
Switching between separate task managers, note apps, and timers wastes time and breaks focus. A unified productivity workspace puts everything you need in one place — tasks with priorities, quick-capture notes, a Pomodoro timer for focused work, and daily planning to set intentions.
V0 generates the entire workspace from prompts — the dashboard layout, task kanban, note editor, and timer component. All mutations use Server Actions so you don't need to build API routes. Clerk via Vercel Marketplace gives you instant authentication.
The architecture uses Next.js App Router with Server Components for data-heavy pages, 'use client' components for interactive elements (kanban drag-and-drop, timer, Cmd+K search), Server Actions for all mutations, and Supabase for persistent storage.
Final result
A full-featured productivity workspace with a today dashboard, kanban task board, searchable notes, Pomodoro timer with session tracking, and daily planning — all synced to your Supabase database.
Tech stack
Prerequisites
- A V0 account (Premium recommended for multiple pages)
- A Supabase project (free tier works — connect via V0's Connect panel)
- A Clerk account (free tier works — enables instant auth via Vercel Marketplace)
- A sense of what your daily productivity workflow looks like
Build steps
Set up the project with auth and database schema
Open V0 and create a new project. Use the Connect panel to add Supabase and enable Clerk via Vercel Marketplace. Then prompt V0 to create the full schema for tasks, notes, time entries, and daily plans.
1// Paste this prompt into V0's AI chat:2// Build a productivity workspace app. Set up Clerk auth and create a Supabase schema with:3// 1. tasks: id (uuid PK), user_id (uuid FK), title (text), description (text), status (text check todo/in_progress/done), priority (text check low/medium/high/urgent), due_date (date), completed_at (timestamptz), created_at (timestamptz)4// 2. notes: id (uuid PK), user_id (uuid FK), title (text), content (text), tags (text[]), is_pinned (boolean default false), created_at (timestamptz), updated_at (timestamptz)5// 3. time_entries: id (uuid PK), user_id (uuid FK), task_id (uuid FK nullable), duration_minutes (integer), started_at (timestamptz), ended_at (timestamptz)6// 4. daily_plans: id (uuid PK), user_id (uuid FK), plan_date (date unique per user), goals (jsonb), reflection (text), created_at (timestamptz)7// Add RLS so users only see their own data.8// Generate SQL migration and TypeScript types.Pro tip: Set CLERK_SECRET_KEY in the Vars tab (no NEXT_PUBLIC_ prefix for the secret). NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY is fine with the prefix since it is a publishable key.
Expected result: Supabase is connected with all four tables created. Clerk is enabled via Vercel Marketplace with sign-in and sign-up working out of the box.
Build the today dashboard with tasks, timer, and notes
Create the main dashboard that shows today's tasks, the active Pomodoro timer, and pinned notes. This is the home screen users see when they open the app.
1// Paste this prompt into V0's AI chat:2// Build a productivity dashboard at app/page.tsx.3// Requirements:4// - Protected by Clerk auth (redirect to sign-in if not authenticated)5// - Three-column layout on desktop, stacked on mobile:6// - Left: Today's tasks (due_date = today OR status = in_progress), each in a shadcn/ui Card with Checkbox for completion, Badge for priority (urgent=red, high=orange, medium=blue, low=gray)7// - Center: Pomodoro timer showing a circular Progress indicator, 25-minute countdown, Start/Pause/Reset Buttons, session count for the day from time_entries8// - Right: Pinned notes (is_pinned = true) in compact Cards with title and first 100 chars9// - Quick-add task Dialog triggered by a floating "+" Button10// - shadcn/ui Command (Cmd+K) for global search across tasks and notes11// - Use Server Components for data fetching, 'use client' for timer and interactive elements12// - Server Actions: createTask(), toggleTaskComplete(), logTimeEntry()Expected result: A three-column dashboard with today's tasks (with completion checkboxes), a Pomodoro timer with progress ring, and pinned notes. Cmd+K opens global search.
Create the task management views with kanban
Build a tasks page with both kanban and list views. The kanban board uses drag-and-drop to move tasks between columns with optimistic UI updates via Server Actions.
1'use client'23import { useOptimistic, useTransition } from 'react'4import { Card } from '@/components/ui/card'5import { Badge } from '@/components/ui/badge'6import { Checkbox } from '@/components/ui/checkbox'7import { updateTaskStatus } from '@/app/actions/tasks'89interface Task {10 id: string11 title: string12 status: 'todo' | 'in_progress' | 'done'13 priority: 'low' | 'medium' | 'high' | 'urgent'14 due_date: string | null15}1617const columns = ['todo', 'in_progress', 'done'] as const18const priorityColors = {19 urgent: 'destructive',20 high: 'default',21 medium: 'secondary',22 low: 'outline',23} as const2425export function KanbanBoard({ tasks }: { tasks: Task[] }) {26 const [isPending, startTransition] = useTransition()27 const [optimisticTasks, setOptimisticTasks] = useOptimistic(28 tasks,29 (state, update: { id: string; status: string }) =>30 state.map((t) => (t.id === update.id ? { ...t, status: update.status as Task['status'] } : t))31 )3233 function handleDrop(taskId: string, newStatus: string) {34 startTransition(async () => {35 setOptimisticTasks({ id: taskId, status: newStatus })36 await updateTaskStatus(taskId, newStatus)37 })38 }3940 return (41 <div className="grid grid-cols-3 gap-4">42 {columns.map((col) => (43 <div44 key={col}45 className="bg-muted/50 rounded-lg p-4 min-h-[400px]"46 onDragOver={(e) => e.preventDefault()}47 onDrop={(e) => handleDrop(e.dataTransfer.getData('taskId'), col)}48 >49 <h3 className="font-semibold mb-3 capitalize">{col.replace('_', ' ')}</h3>50 {optimisticTasks51 .filter((t) => t.status === col)52 .map((task) => (53 <Card54 key={task.id}55 className="p-3 mb-2 cursor-grab"56 draggable57 onDragStart={(e) => e.dataTransfer.setData('taskId', task.id)}58 >59 <div className="flex items-center gap-2">60 <Checkbox />61 <span className="text-sm flex-1">{task.title}</span>62 <Badge variant={priorityColors[task.priority]}>{task.priority}</Badge>63 </div>64 </Card>65 ))}66 </div>67 ))}68 </div>69 )70}Pro tip: Use V0's Design Mode (Option+D) to visually adjust the kanban column widths, card spacing, and Badge colors for free without consuming credits.
Expected result: A kanban board with three columns (Todo, In Progress, Done). Tasks can be dragged between columns with optimistic UI updates — the UI moves the card instantly while the Server Action persists in the background.
Build the Pomodoro timer component
Create a client-side timer component that counts down 25 minutes, plays a notification sound, and logs completed sessions as time entries linked to the active task.
1'use client'23import { useState, useEffect, useCallback } from 'react'4import { Button } from '@/components/ui/button'5import { Progress } from '@/components/ui/progress'6import { Card } from '@/components/ui/card'7import { logTimeEntry } from '@/app/actions/tasks'89const WORK_MINUTES = 2510const BREAK_MINUTES = 51112export function PomodoroTimer({ activeTaskId }: { activeTaskId?: string }) {13 const [seconds, setSeconds] = useState(WORK_MINUTES * 60)14 const [isRunning, setIsRunning] = useState(false)15 const [isBreak, setIsBreak] = useState(false)16 const [sessions, setSessions] = useState(0)1718 const totalSeconds = (isBreak ? BREAK_MINUTES : WORK_MINUTES) * 6019 const progress = ((totalSeconds - seconds) / totalSeconds) * 10020 const minutes = Math.floor(seconds / 60)21 const secs = seconds % 602223 const completeSession = useCallback(async () => {24 if (!isBreak) {25 setSessions((s) => s + 1)26 await logTimeEntry(WORK_MINUTES, activeTaskId)27 }28 setIsBreak(!isBreak)29 setSeconds((!isBreak ? BREAK_MINUTES : WORK_MINUTES) * 60)30 setIsRunning(false)31 }, [isBreak, activeTaskId])3233 useEffect(() => {34 if (!isRunning) return35 const interval = setInterval(() => {36 setSeconds((s) => {37 if (s <= 1) {38 completeSession()39 return 040 }41 return s - 142 })43 }, 1000)44 return () => clearInterval(interval)45 }, [isRunning, completeSession])4647 return (48 <Card className="p-6 text-center">49 <p className="text-sm text-muted-foreground mb-2">50 {isBreak ? 'Break Time' : 'Focus Time'}51 </p>52 <div className="text-4xl font-mono font-bold mb-4">53 {String(minutes).padStart(2, '0')}:{String(secs).padStart(2, '0')}54 </div>55 <Progress value={progress} className="mb-4" />56 <div className="flex gap-2 justify-center">57 <Button onClick={() => setIsRunning(!isRunning)}>58 {isRunning ? 'Pause' : 'Start'}59 </Button>60 <Button61 variant="outline"62 onClick={() => {63 setIsRunning(false)64 setSeconds(WORK_MINUTES * 60)65 setIsBreak(false)66 }}67 >68 Reset69 </Button>70 </div>71 <p className="text-sm text-muted-foreground mt-3">72 Sessions today: {sessions}73 </p>74 </Card>75 )76}Expected result: A Pomodoro timer with 25-minute work / 5-minute break cycles, a visual progress bar, Start/Pause/Reset buttons, and automatic session logging to Supabase via Server Action.
Add the notes editor and global search
Build a notes page with a searchable grid of note Cards and the Cmd+K command palette for global search across both tasks and notes.
1// Paste this prompt into V0's AI chat:2// Build two features:3// 1. Notes page at app/notes/page.tsx:4// - Grid of note Cards showing title, first 150 chars of content, tags as Badges, pin icon for is_pinned5// - Search Input at top that filters notes by title and content6// - "New Note" Button opens a Dialog with Input for title, Textarea for content, ToggleGroup for tags (work/personal/ideas/reference)7// - Server Actions: saveNote(), togglePin(), deleteNote()8// 2. Global search Command component (Cmd+K):9// - shadcn/ui Command component with CommandInput, CommandList, CommandGroup10// - Two groups: Tasks and Notes11// - Search across task titles and note titles/content12// - Clicking a result navigates to the task or note13// - Add this to the root layout so it's available on every page14// - 'use client' component with useEffect for keyboard shortcut listenerExpected result: A notes page with searchable grid layout and tag filtering. Pressing Cmd+K anywhere opens a global search modal that finds tasks and notes by title and content.

Add calendar integration
Connect Google Calendar via OAuth to display tasks with due dates alongside calendar events, and auto-create calendar blocks for Pomodoro focus sessions.
Add recurring tasks
Implement recurring task templates that automatically create new tasks on a daily, weekly, or custom schedule using Supabase pg_cron.
Build a weekly review page
Create a weekly summary page showing completed tasks, total focus time, and reflection prompts based on daily plan data.
Add collaborative workspaces
Enable shared task boards where multiple users can collaborate on projects, assign tasks to each other, and see real-time updates via Supabase Realtime.
Common pitfalls
Pitfall: Putting the Pomodoro timer in a Server Component
How to avoid: Mark the timer component with 'use client' at the top. All interactive components (timer, kanban drag-and-drop, Command palette) must be client components.
Pitfall: Not using optimistic updates for kanban drag-and-drop
How to avoid: Use React's useOptimistic hook to immediately move the card in local state while the Server Action persists the change in the background.
Pitfall: Fetching all tasks and notes in the Command palette on every keystroke
How to avoid: Pre-fetch task and note titles on Command open, then filter client-side. For large datasets, add a 300ms debounce before making search queries.
Best practices
- Use Server Actions for all mutations (task CRUD, note saving, time logging) — no API routes needed for this project
- Use V0's Design Mode (Option+D) to visually arrange the dashboard layout for free without consuming credits
- Keep the Pomodoro timer as a separate 'use client' component to avoid re-rendering the entire dashboard on each tick
- Use useOptimistic for kanban drag-and-drop to provide instant visual feedback while Server Actions persist in the background
- Set up the shadcn/ui Command component in the root layout so global search is available on every page
- Use revalidatePath after each Server Action to refresh the affected pages with fresh data from Supabase
AI prompts to try
Copy these prompts to build this project faster.
I'm building a productivity app with Next.js App Router, Supabase, and Clerk. I need help with the daily planning feature. Design a daily_plans table with goals (as a JSONB array of objects with text and is_completed boolean) and reflection (text). Write a Server Action that upserts the plan for today's date (insert if new, update if exists) and a Server Component that fetches and displays the plan with editable goal checkboxes.
Build a Pomodoro timer component using shadcn/ui. It should count down from 25:00, show a circular Progress indicator, have Start/Pause/Reset buttons, automatically switch to a 5-minute break after work completes, track session count, and call a logTimeEntry Server Action when each work session finishes. Mark it as 'use client' and use useEffect for the interval.
Frequently asked questions
What V0 plan do I need for this productivity app?
V0 Free works for basic features, but Premium ($20/month) is recommended because the app has multiple pages (dashboard, tasks, notes, planning) that benefit from prompt queuing to generate them efficiently.
Can the Pomodoro timer track time against specific tasks?
Yes. The timer component accepts an activeTaskId prop. When a Pomodoro session completes, the logTimeEntry Server Action links the time entry to that task via the task_id foreign key.
Does the app work offline?
Not in this base build since it relies on Supabase for data storage. You could add offline support by implementing local storage caching with sync-on-reconnect logic.
How do I deploy the productivity app?
Click Share then Publish to Production in V0. Set CLERK_SECRET_KEY in the Vars tab without NEXT_PUBLIC_ prefix. Supabase credentials are auto-configured from the Connect panel.
Can I use this with a team instead of just personal use?
The base build is single-user. To add team features, extend the schema with a teams table and shared tasks, then update RLS policies to allow team members to view each other's tasks.
