Visual daily planner and time-blocking application

The verdict: can you vibe code Structured?
Build a personal web-based clone with Next.js and Supabase for your own time-blocking needs, but keep paying for the real iOS app if you want polished native mobile widgets and flawless system calendar sync.
Replicating a snappy time-blocking vertical timeline with AI task parsing is entirely achievable for a solo developer using modern AI tools. However, getting native mobile widgets, flawless bi-directional system calendar sync (Apple EventKit / Google Calendar OAuth edge cases), and buttery drag-and-drop performance on mobile without building native apps is tedious. For personal use, building a web-first dashboard backed by Turso and an LLM parsing endpoint is a satisfying 2-weekend build.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- 15 million user network effect and App Store chart dominance
- Deep native Apple Ecosystem integrations (watchOS complications, live activities, native widgets)

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js project with Tailwind CSS, shadcn/ui, Turso database connection, and better-auth user authentication.
Scramble a fresh Next.js application using TypeScript, Tailwind CSS, and Turso via libSQL for persistence. Set up better-auth for single-user credential authentication. Create a database schema for users, daily timelines, and time-block tasks. Tasks must include fields for title, start_time, duration_minutes, icon, completed status, category, and date. Ensure migrations run cleanly on startup. Output the complete project structure and config files.02Vertical Chronological Timeline UI
Build the core visual daily planner interface featuring a vertical chronological hour-by-hour timeline where tasks snap into time slots.
Create a responsive Next.js dashboard view for Structured. Build a vertical chronological timeline component spanning 24 hours with hour markers. Implement drag-and-drop or click-to-add functionality allowing users to drop tasks into specific time slots with custom durations. Tasks should visually stack along the timeline without overlapping. Include side drawers for editing task details, icons, and notes.03AI Natural Language Task Parsing
Integrate the Vercel AI SDK and OpenAI API to parse natural language dictation or messy text into structured timeline blocks.
Implement an AI assistant drawer using the Vercel AI SDK and OpenAI API. Create a server action that accepts unstructured natural language text (e.g., 'Gym at 7am for 45 minutes, then team sync at 10am for an hour') and parses it into a JSON array of structured task objects matching our database schema. Render a preview modal where users can review and batch-add the parsed tasks directly onto their daily timeline.04Recurring Tasks & External Calendar Integration
Add support for recurring task generation rules and external calendar event fetching.
Add a recurring task engine that evaluates recurrence rules (daily, weekly, weekdays) and automatically populates tasks into the daily timeline. Also, build an API route integration for Google Calendar that fetches external events for the selected date and displays them alongside personal tasks on the chronological timeline with distinct styling. Handle timezone conversions safely.05Polish, Sync, and Deployment
Finalize state management for real-time cross-device updates, clean up UI animations, and deploy to Cloudflare.
Add client-side state persistence and optimistic updates for task completion and reordering. Implement Sentry for error tracking and PostHog for usage analytics. Create a deployment configuration for Cloudflare Workers/Pages. Verify all UI transitions are smooth and responsive on both desktop and mobile viewports. Write clear documentation in README.md on local setup and environment variables.
