Can I build my own Trello with AI?

Build a kanban task board app similar to Trello for personal or small-team use.

**Objective:** Let users organise tasks on a visual board with draggable columns and cards.

**Target user:** A freelancer, small team, or side-project builder who wants a simple task board without Trello's monthly fees or feature bloat.

**Core functionality:**
- Create a board with named lists (columns), e.g. To Do, In Progress, Done
- Add, edit, and delete cards within each list
- Drag and drop cards between lists (or use move buttons as a fallback on mobile)
- Card details: title, description, optional due date, optional labels
- Persist all data so the board loads correctly on refresh

**Pages/screens:**
- Main board view (lists displayed horizontally, scrollable on mobile)
- Card detail modal or slide-over panel
- Optional board settings (rename lists, add/delete lists)

**User flows:**
1. User opens board and sees all lists with their cards
2. User clicks "Add card" in a list, enters a title, card appears
3. User drags card to another list (or taps "Move to…" on mobile)
4. User clicks a card to view/edit description and due date
5. Changes persist immediately

**UI direction:**
- Clean, card-based layout similar to Trello's familiarity
- Lists as vertical columns with subtle background colour
- Cards with white background, rounded corners, light shadow
- Labels as small coloured pills
- Due dates shown in muted text, highlighted when overdue

**Data model:**
- Board: { id, title, createdAt }
- List: { id, boardId, title, position }
- Card: { id, listId, title, description, dueDate, labels[], position }

**Authentication:** Optional for MVP if single-user. Add simple login if multiple people need separate boards.

**APIs/integrations:** None required for MVP.

**Responsive requirements:** Board scrolls horizontally on mobile. Drag-and-drop should degrade gracefully to tap-to-move on touch devices.

**Error states:** Prevent empty card titles. Show loading state while fetching board data. Handle failed saves with a retry message.

**Deployment:** Host on the AI builder's default hosting with database included.

**Explicit exclusions:** No real-time collaboration, no file attachments, no checklists, no automation rules, no Power-Up integrations, no comments/@mentions in v1.

**Suggested implementation order:**
1. Board layout with static lists and cards
2. CRUD operations for cards and lists
3. Drag-and-drop or move-between-lists
4. Card detail panel with description and due date
5. Labels and polish
6. Optional authentication for multi-user
