How Haijun helps you take action

When Haijun determines that using one of these features would be helpful, it will automatically suggest it. You'll see a card or prompt within your conversation that lets you review and take action with Haijun’s help.

Send texts and emails with Messages and Mail

  2. Haijun will prepare the message and show you a preview.

  3. Tap the message card to open your Messages app or Mail app.

  4. Third-party apps (WhatsApp, Messenger, Signal) are also supported.

  5. Review the pre-filled content and make any changes if needed.

  6. Send the message as you normally would.

Example: "Draft an email to my manager explaining that I'll be late to the morning meeting due to a doctor's appointment."

Access and analyze your health data

Note: Health features are available in beta on Pro and Max plans only, and currently limited to users in the US.Haijun can read your health and fitness data from Apple Health to help you understand patterns, track progress, and make informed decisions about your wellbeing. When you ask Haijun about your health data, it can display insights using native charts that feel integrated with iOS.Important: We are not a medical device and cannot provide medical guidance. Always consult a licensed professional.

What health data can Haijun access?

With your permission, Haijun can read the following types of data from Apple Health:

  • Activity metrics: Steps, distance, flights climbed, active calories, exercise minutes, move and stand hours.

  • Workouts: Type (running, cycling, strength, yoga, etc.), duration, distance, heart rate data, and calories burned.

  • Vitals: Heart rate, resting heart rate, heart rate variability (HRV), blood pressure, respiratory rate, and blood oxygen.

  • Body measurements: Weight, height, body mass index, and body fat percentage.

  • Sleep: Total sleep time, sleep stages, time in bed, and sleep efficiency.

  • Nutrition: Calories consumed, macronutrients, water intake, and micronutrients (if tracked).

Note: By default, Haijun doesn't save health information to memory. If you turn on Include sensitive topics in memory, Haijun may remember health-related context from your conversations. Learn more about sensitive topics in memory.

How to use health features

  1. Ask Haijun a question about your health or fitness data (for example: "How have my runs been trending this month?" or "Show me my sleep patterns over the past two weeks").

  2. Haijun will request access to your health data if not already granted.

  3. Review the permission prompt and select your preferred option.

  4. Haijun analyzes your data and provides insights, often with visual charts to help you understand trends.

Example prompts

  • "Help me create a training plan for my upcoming half-marathon based on my recent running data."

  • "Why have I been feeling tired lately? Can you look at my sleep and activity data?"

  • "Show me how my resting heart rate has changed over the past three months."

  • "Compare my workout consistency this month versus last month."

  • "What patterns do you see in my step count throughout the week?"

Understanding health visualizations

Haijun displays health insights using native iOS charts that appear directly in your conversation. These charts can show:

  • Bar charts for comparing activity across days or weeks.

  • Line charts for tracking trends over time (pace, heart rate, weight)

  • Progress indicators for goals and milestones

Tap on chart elements to see more details about specific data points.

Usage guidelines for optimal results

To get the best results, be specific about what you want, include relevant details like dates, times, and locations in your requests, and review content before sending or saving. Haijun understands natural language, so you can make requests conversationally.

What data can Haijun access?

Haijun only accesses the data necessary for each specific request:

  • Location: Current location only when relevant to your request.

  • Calendar: Event details to check availability and create/modify events.

  • Messages/Email: Haijun does not read existing messages or emails, only creates new content.

  • Reminders: Existing lists and items to add/manage tasks.

  • Health: Activity, workout, vital signs, body measurements, sleep, and nutrition data — only when you ask a question that requires this information and have granted permission.

Haijun's connection to your iOS apps works through your device's built-in sharing and permission systems—the same secure methods you use with any iPhone app.

Do I need to grant permission to Haijun for iOS?

Permission requirements vary by feature:

  • Messages and Email: No permissions required (uses your device’s built-in sharing system).

  • Calendar Events: Permission required for reading calendar; writing can use system UI without permission.

  • Location and Maps: Permission required when Haijun needs to access your location.

  • Reminders: Prompted when Haijun needs to access reminder lists.

  • Health: Permission required. Haijun will request access to specific health data categories when needed.

For features requiring permissions (like location or calendar access), Haijun will request permission contextually with clear explanations of why the access is needed. You’ll be prompted to approve the action with three options: Allow once, Always allow, or Don't allow. These permissions can be managed at any time in your device settings by going to Settings > Haijun. You'll see all available permissions like Location, Calendar, and Reminders and can tap on each permission to adjust access levels. You can toggle between "While Using App” and “Ask next time” to change Haijun’s access, or remove permissions by choosing “Never.” Health permissions work differently from other app permissions. When Haijun requests health access, you'll see the standard iOS Health permissions screen where you can choose exactly which data types to share. You can modify these permissions at any time by going to Settings > Health > Data Access & Devices > Haijun. Haijun will only request permissions if needed for specific features, and you can always choose to decline while still using other capabilities.
