Can I build my own Notion with AI?

Build a focused workspace app inspired by Notion, pages + simple database, not a full clone.

**Objective:** Create a personal/team wiki where users organise pages in a sidebar and maintain one simple database (e.g. projects or contacts) with table view.

**Target user:** A small team or solo founder who wants a Notion-like hub for docs and a single structured database, without block editor complexity.

**Core functionality:**
- Sidebar page tree: create, rename, nest, and delete pages
- Rich-text page editor (headings, paragraphs, bullet lists, bold/italic, links)
- One database with custom columns: text, number, date, select (single), checkbox
- Table view: add/edit/delete rows, sort by column, filter by select value
- Full-text search across page titles
- Workspace with user login; all members see shared pages

**Pages/screens:**
- App shell: collapsible sidebar + main content area
- Page editor view
- Database table view
- Search results overlay
- Settings: workspace name, member list (simple)

**User flows:**
1. User logs in and sees sidebar with pages and one "Projects" database
2. User creates a new page, writes content, auto-saves
3. User opens database, adds a row with name, status, due date
4. User nests a page under another via drag or "move under" menu
5. User searches "onboarding" and jumps to matching page

**UI direction:**
- Notion-adjacent: clean white/grey palette, sidebar icons for pages vs database
- Comfortable reading width for page content
- Table view with inline editing (click cell to edit)
- No slash commands or block handles in v1, standard toolbar is fine

**Data model:**
- Workspace: { id, name }
- Page: { id, workspaceId, parentId?, title, content (JSON or HTML), sortOrder, updatedAt }
- Database: { id, workspaceId, name, columns[] }
- Column: { id, name, type, options? }
- Row: { id, databaseId, cells: { columnId: value } }

**Authentication:** Email login; users belong to one workspace for MVP.

**APIs/integrations:** None for v1. Export to Markdown optional stretch goal.

**Responsive requirements:** Sidebar collapses to hamburger on mobile; page reading works on phone; table view scrolls horizontally.

**Error states:** Empty sidebar → "Create your first page" CTA; unsaved changes warning on navigate away; concurrent edit → last-write-wins with timestamp notice (no realtime in v1).

**Deployment:** Standard AI builder hosting with database.

**Explicit exclusions:** No block drag-and-drop, no database relations/rollups/formulas, no real-time collaboration, no comments, no version history, no public page publishing, no template gallery.

**Suggested implementation order:**
1. Auth + workspace + sidebar page tree
2. Rich-text page editor with auto-save
3. Database schema + table UI
4. Search across titles
5. Mobile sidebar and polish
