Frequently Asked Questions

Daychat is an AI-powered calendar assistant for iPhone that connects to your Google Calendar. Instead of tapping through menus, you manage your schedule through natural conversation — create events, check availability, get smart reminders, and more.

Daychat connects securely to your Google Calendar through Google's official OAuth2 authentication. Once connected, you can create, modify, and delete events by chatting naturally. Events created through Daychat appear on your Google Calendar immediately, and changes you make in Google Calendar sync back to Daychat.

Almost anything related to your calendar:

• Create events — "Schedule a meeting tomorrow at 2pm"
• Check your schedule — "What do I have this week?"
• Modify events — "Move my dentist appointment to Thursday"
• Add guests — "Invite Sarah to the team lunch"
• Timezone queries — "What time is it in Tokyo?"
• Find free time — "When am I free on Friday?"

No. Daychat only accesses email metadata — sender name, subject line, and date. It never reads the content of your emails. This metadata is used solely to send you notifications about important emails like delivery updates, appointment confirmations, and travel bookings.

Daychat supports 10+ languages including English, French, Spanish, German, Chinese (Traditional), Korean, Malay, Portuguese, Thai, and Vietnamese. The AI assistant responds in your chosen language, and all notifications are localized.

Yes. Daychat uses Google's official OAuth2 for authentication and follows Google's API Services User Data Policy, including Limited Use requirements. Calendar data is processed securely through Firebase Cloud Functions. Daychat never shares your data with third parties.

Daychat is available on iPhone (iOS 17+), iPad, and Mac. Your messages and settings sync across all your Apple devices automatically.

Smart notifications are context-aware reminders that adapt their timing based on the type of event:

• Flights — evening before + 3 hours before departure
• Meetings & calls — 30 minutes before
• Restaurants — 1 hour before
• Entertainment — 2 hours before
• Medical appointments — 1 hour before

The AI also generates personalized, friendly messages instead of generic reminders.

Yes, with Daychat Plus or Pro. Tap the microphone button, speak naturally ("Lunch with Sarah on Friday at noon at the Italian place"), and Daychat transcribes your voice and creates the event with all the details parsed automatically.

Daychat Pro includes weather alerts for rain, snow, extreme heat, extreme cold, and high winds — delivered about an hour before the weather event. It also provides air quality alerts and pollen alerts for allergy sufferers, plus a 7-day weather forecast accessible through chat.

Every Saturday at 11 AM, if your weekend looks free, Daychat sends you 3 local activity suggestions based on your interests and location. These are real events and activities happening near you, found using AI with real-time search — not generic recommendations.

Unlike Siri, Daychat is a conversational assistant specifically designed for calendar management. It understands follow-up context ("actually, make it 3pm instead"), sends proactive smart notifications with timing based on event type, provides weather and environmental alerts, and suggests weekend activities. It's a dedicated calendar companion, not a general voice assistant.
