The calendar your Boox tablet deserves
Write with your stylus. Sync with Google Calendar. Plan with AI. Finally, a planner designed for e-ink.
Generic calendar apps weren't made for e-ink
You invested in a Boox tablet for focused, distraction-free productivity. But every calendar app you've tried was designed for phones—tiny buttons, flashy animations, and no stylus support.
- Touch targets too small for stylus precision
- Animations that cause e-ink ghosting
- No handwriting integration
- Can't link notes to calendar events
- No AI-enabled features
BooxDay: Built from the ground up for Boox
We used the official Onyx SDK to create a calendar that feels native to your tablet. Every pixel, every interaction, every feature—designed specifically for e-ink displays and stylus input.
- Large touch targets, stylus-optimized UI
- Zero animations, instant refresh
- Full pressure-sensitive handwriting
- Deep Boox Notes integration
- AI-enabled, intelligent Calendar Agent

SemanticGenius: Your notes, intelligently connected
Write naturally in BooxDay or Boox Notes. SemanticGenius automatically understands your handwriting, extracts keywords, people, and dates, then links notes to related calendar events.
Tasks that feel like paper, work like software
Write your to-dos naturally with your stylus. BooxDay adds the structure—checkboxes, priorities, smart suggestions, and AI-powered assistance—without losing the feel of pen on paper.
Your intelligent planning partner
BooxDay's AI doesn't just assist—it collaborates. From voice input to smart scheduling, your calendar becomes proactive.
Plan My Day
Your AI scheduling strategist. Analyzes tasks, events, and your energy patterns to propose the perfect daily flow—because your morning brain and afternoon brain work differently.
Voice-to-Event
Speak naturally, schedule instantly. Say "Meeting with Sarah next Tuesday at 3pm" and watch it appear on your calendar. No typing, no tapping, just talking.
Handwriting Recognition
Your scribbles, decoded. Our 3-stage AI pipeline transforms your handwritten notes into formatted, searchable text—even when your handwriting gets creative.
Memo Summarization
Pages of notes, distilled to essence. AI reads through your handwritten pages and extracts key points, action items, and insights you might have missed.
Voice-to-Text
Smart dictation that gets you. Adaptive silence detection waits for you to finish thoughts—no more cut-off sentences. Speak at your pace, not the machine's.
Voice-to-Task
Speak your to-dos into existence. Say "Buy groceries, high priority, by Friday" and AI parses it all—task, priority, deadline. Your voice becomes your productivity tool.
Intelligent Task Breakdown
Big goals, bite-sized steps. AI analyzes overwhelming tasks and suggests logical subtasks. "Plan vacation" becomes 10 manageable actions you can actually complete.
Smart Planning & Suggestions
Proactive, not reactive. AI spots zombie tasks that keep migrating, suggests time blocks for deep work, and flags when you're overcommitting. Your calendar finally fights back.
AI Prioritization Tool
Decisions, delegated. Based on your patterns, deadlines, and context, AI suggests which tasks deserve your attention first. Stop deciding what to do—start doing.
