Your AI Powered
Calendar Assistant

CalUnity's AI understands your schedule, helps you plan smarter and keeps you in control. Ask anything about your calendar in plain English, no buttons, no menus, just conversation.

Natural Language Control

"Schedule lunch with Sarah next Tuesday at noon", just type what you want and AI handles the rest.

Talk to your calendar like a person

Smart Insights

AI analyzes your patterns and gives you a clear picture of how your time is spent across all calendars.

Understand your time like never before

Conflict Detection

AI spots overlapping events, tight gaps between meetings and suggests the best way to resolve conflicts.

Never double-book again

You Stay in Control

AI never modifies your calendar without asking. Every action requires your explicit approval first.

Zero changes without your permission
PRIVACY FIRST

Your Data.
Your Rules.

We built CalUnity with a simple principle: your calendar data belongs to you. We don't sell it, we don't mine it and we never touch your calendars without your say-so.

Read-Only by Default

We never write to your calendars unless you explicitly grant write permission.

Calendars Stay Separate

Events live in their origin calendar. No cross-account copies, no clutter, no duplicates.

Encrypted & Secure

All data is encrypted in transit and at rest. Your tokens are securely stored.

Full Transparency

See exactly what data we access. Revoke permissions anytime with one click.

No Data Selling

Your calendar data is never sold, shared with advertisers or used for profiling.

Independent product

CalUnity is the only fully-free unified calendar app with a native Android app, support for all four major providers (Google, Microsoft, Apple iCloud and CalDAV), and a built-in AI assistant included at no cost. Read-only by default keeps your data safe, and CalUnity is an independent product, not part of a larger productivity suite.

FAQ

Frequently Asked Questions

Which calendar providers does CalUnity support?
CalUnity supports Google Calendar, Microsoft Outlook/365, Apple iCloud Calendar and any CalDAV-compatible server. You can connect multiple accounts from different providers and see them all in one unified view.
How does the AI calendar assistant work?
CalUnity's built-in AI assistant lets you manage your schedule using natural language. You can say things like "Schedule lunch with Sarah next Tuesday at noon" or ask "What does my week look like?" The AI understands context across all your connected calendars and never makes changes without your explicit approval.
Is my calendar data private and secure?
Yes. CalUnity is privacy-first by design. Calendar data is encrypted in transit over HTTPS and at rest in the database. Tokens are stored using industry-standard encryption. Your data is never sold, shared with advertisers or used for ad profiling. CalUnity operates in read-only mode by default — write access requires explicit user opt-in. You can revoke access to any connected account at any time with one click, and account deletion permanently removes all associated data.
Are there mobile apps available?
Yes. CalUnity offers native iOS and Android apps so you can access all your unified calendars on the go. The mobile apps include the same AI assistant, multi-provider sync and privacy protections as the web version.
Is CalUnity free to use?
CalUnity is completely free to use, including the AI assistant, multi-provider sync and unified calendar view.
How do I link multiple calendar accounts?
Just sign in with Google, Microsoft, Apple or any CalDAV server. CalUnity automatically detects and connects all your calendars. You can add more accounts anytime from settings.
Does CalUnity sync events between my calendars?
No. CalUnity shows all your calendars in one unified view, but each event stays in its origin account. We never copy, duplicate or propagate events between your Google, Microsoft, Apple or CalDAV accounts. This keeps your calendars clean — no auto-generated "busy" blocks cluttering your work calendar from a personal event, no sync failures to clean up and no risk of accidentally exposing private events to colleagues. You see everything together; the data stays where it belongs.
