Google just launched CC, an AI agent that emails you a daily briefing. Microsoft’s Copilot can schedule meetings by chat. Gemini sits inside your calendar, ready to help. The Google Calendar AI features and Outlook Copilot integrations are more powerful than ever.

But after testing Google’s new CC agent, Gemini features, and Outlook’s Copilot, here’s what they can actually do for your scheduling—and where they still fall short.

This guide breaks down every AI calendar feature available in Google and Microsoft’s ecosystems right now, plus how they compare to Carly, an AI assistant that works through email and text. No marketing fluff. Just an honest look at what works, what doesn’t, and when you might need something that goes beyond native AI.

What’s New: Google Calendar’s AI Features

Google has been rolling out AI features across its workspace products at a rapid pace. Here’s what’s available now and what to expect heading into 2026.

Gemini Integration in Google Calendar

The Gemini side panel in Google Calendar lets you interact with AI directly from the calendar interface. You can ask Gemini to create events, find free time slots, or get information about your schedule.

To use it, look for the Gemini icon in the right sidebar of Google Calendar on the web. Click it, and you can type natural language requests like “Schedule a team meeting next Tuesday at 2pm” or “When am I free this week?”

What Gemini does well in Calendar:

• Creates single events quickly from natural language
• Finds open time slots on your calendar
• Answers questions about your existing schedule
• Works with voice commands through Google Assistant

The limitation: Gemini in Calendar primarily works with your own calendar. It can suggest times when you’re free, but it can’t see other people’s availability unless they’ve explicitly shared their calendars with you.

”Help Me Schedule” in Gmail (October 2025)

Google launched “Help me schedule” in Gmail on October 15, 2025. This feature appears when you’re composing an email and need to propose meeting times.

Here’s how it works:

1. Start composing an email in Gmail
2. Click the “Help me schedule” button (looks like a calendar icon)
3. Gemini analyzes the email context and your calendar
4. It suggests available time slots based on the conversation

The feature is context-aware, meaning it reads the email thread to understand what kind of meeting you’re scheduling. If someone emails asking for a 30-minute call, Help me schedule pulls times that fit.

What’s genuinely useful: You don’t have to switch between Gmail and Calendar. The AI handles the context switch for you and proposes times without leaving your inbox.

NEW: Google Labs CC (December 2025)

Google Labs just launched CC on December 16, 2025. This experimental AI agent validates something important: users want AI that works through email, not another app to learn.

CC sends you a “Your Day Ahead” briefing each morning. It synthesizes your calendar, tasks, and emails into one summary delivered to your inbox.

How CC works:

• Email-based interaction: You communicate with CC by emailing [yourusername]+cc@gmail.com
• Daily briefing: Each morning, CC sends a summary of your day including meetings, deadlines, and important emails
• Connected services: It pulls from Gmail, Google Calendar, Google Drive, and web content
• Learning over time: Reply to CC to teach it your preferences or add items to your to-do list

What CC does for your calendar:

• Summarizes upcoming meetings and schedule
• Highlights time-sensitive deadlines
• Prepares calendar links for quick scheduling
• Pulls context from calendar events for personalized summaries

What CC cannot do:

• Send emails to other people
• Coordinate times with external contacts
• Work outside the Google ecosystem

CC is currently available only in the US and Canada, requires a paid Google AI subscription, and has a waitlist. It also only works with personal Gmail accounts, not Google Workspace business accounts.

The takeaway: CC proves that email-based AI assistants are the future. But CC summarizes your calendar without actually doing the scheduling work.

Smart Features You Already Have

Before chasing new AI features, remember what Google Calendar already does automatically:

Auto-adding events from Gmail: Flight confirmations, restaurant reservations, and event tickets from your inbox automatically appear on your calendar. This has worked for years and remains one of the most useful passive features.

Suggested times for guests: When you add guests to a new event, Calendar suggests times when everyone appears free (based on shared calendars).

Travel time integration: If you add a location to an event, Calendar can block travel time before the meeting based on your starting location.

Time Insights: See analytics on how you spend your time, broken down by meeting type and duration.

Focus Time: Block recurring time for deep work, and Calendar will decline meetings that conflict.

What’s New: Outlook Calendar’s Copilot Features

Microsoft has been integrating Copilot across the entire Microsoft 365 suite. Here’s what it can do specifically for your calendar.

Copilot in Outlook Calendar

Copilot appears as a chat panel in Outlook where you can schedule meetings conversationally. Type something like “Schedule a meeting with Sarah next week for 30 minutes” and Copilot will find available times and create the event.

Key capabilities:

• Natural language scheduling: Describe what you need in plain English
• Conflict awareness: Copilot checks your calendar before suggesting times
• Meeting preparation: Get summaries of relevant emails and documents before important meetings
• Agenda generation: Copilot can draft meeting agendas based on the invite and context

Microsoft announced at Ignite 2025 that automatic conflict resolution is rolling out now through late January 2026. This lets Copilot proactively reschedule flexible 1:1 meetings when it detects overlapping commitments—though only for meetings you’ve marked as “okay to reschedule.”

Voice Experience (Mobile)

Outlook mobile now supports voice commands for calendar tasks. You can:

• Create events by speaking
• Check your schedule hands-free
• Use one-tap prompts for common calendar actions

This is useful when you’re on the go and can’t type out a request.

Search and Organization

Copilot enhances how you find and organize calendar information:

• Search by category: Ask Copilot to find all meetings with a specific person or about a particular project
• Pattern recognition: Copilot can identify recurring meeting types and help you manage them more efficiently

The Limitations: What Native AI Can’t Do Yet

After testing all three AI calendar tools extensively, here are the gaps that affect real-world scheduling.

Both Platforms Share These Limitations

Ecosystem lock-in: Google’s AI only works with Google Calendar and Gmail. Microsoft’s Copilot only works with Outlook. If you’re scheduling with someone outside your ecosystem, the AI can’t help coordinate. Carly works with Google Calendar, Outlook, and Apple Calendar—so you can coordinate with anyone.

1:1 scheduling only: Both Gemini and Copilot handle simple one-on-one meeting requests. Try to schedule a meeting with three people from different companies, and you’re back to email chains. Carly handles group scheduling across multiple people and companies.

No external contact support: The AI can suggest times when you’re free, but it can’t check availability for contacts who haven’t shared their calendars. That’s most of the people you actually need to schedule with. Carly coordinates directly with your contacts via email—no calendar sharing required.

Requires being in the app: To use Gemini or Copilot, you need to be in Calendar or Outlook. CC works through email, but it only summarizes and doesn’t actually schedule. Carly works entirely through email and text—no app to open.

No follow-up automation: If someone doesn’t respond to your proposed times, you’re responsible for following up. The AI doesn’t handle the back-and-forth. Carly sends follow-ups automatically and manages the entire conversation.

Limited image processing: Neither platform reliably parses complex itineraries from screenshots, conference schedules from photos, or school calendars from PDFs. You still need to manually enter most of this information. Snap a photo and text it to Carly—she extracts every event automatically.

The Overscheduling Problem

Research from March 2025 found that AI systems got clock-hand positions right less than 25% of the time. While this study focused on visual reasoning, it highlights a broader truth: AI still struggles with nuanced time-based decision making.

Native calendar AI will fill your open slots with meetings. It doesn’t understand that you need buffer time, that back-to-back video calls are exhausting, or that some meetings are more important than others.

Reclaim.ai claims their users save 7.6 hours per week with AI scheduling. But that number assumes the AI is making good decisions about how to allocate your time. If AI fills every gap, you might technically save scheduling time while losing focus time.

When You Need More Than Native AI

Native AI features are genuinely useful for:

• Quick event creation in your own calendar
• Finding your free slots
• Simple 1:1 scheduling within your organization

You need something more when:

• Coordinating with people outside your organization: Clients, vendors, partners, interview candidates—this is where Carly excels
• Group scheduling: Any meeting with more than two people
• Processing complex inputs: Travel itineraries, conference schedules, school calendars, screenshots
• Zero-friction workflow: When you don’t want to open an app just to schedule

If any of these describe your scheduling needs, native AI will frustrate you. You’ll end up doing the work manually anyway.

A Simpler Approach: Scheduling Without Another App

Here’s what the native AI features prove: you don’t need a complicated interface to schedule meetings. The best scheduling happens in the tools you already use.

Google’s CC agent validates this by working through email. But CC only summarizes your calendar. It won’t actually book meetings or coordinate with other people.

What if you could forward a scheduling email and have someone handle the back-and-forth? Or text a request and have it show up on your calendar?

That’s exactly what Carly does—and she goes far beyond what CC, Gemini, or Copilot can offer.

How Carly Works

Forward any email: Got a flight confirmation? Forward it. Conference schedule PDF? Forward it. Someone asking to meet? Forward it. Carly reads the email and adds every event to your calendar automatically.

Text like you’d text a friend: “Add dentist appointment Friday at 2” or “Schedule coffee with Mike sometime next week” just works. No commands to learn.

CC her on scheduling threads: Adding carly@usecarly.com to a CC lets Carly coordinate times with everyone—handling the back-and-forth until the meeting is booked.

Snap photos of schedules: Take a picture of a conference schedule, travel itinerary, or your kid’s school calendar. Carly extracts every event and adds them.

No new app to learn. No interface to navigate. If you can email or text, you can use Carly.

What Makes Carly Different from Native AI

Capability	Native AI (Gemini/Copilot/CC)	Carly
Works across Google, Outlook, Apple	❌	✅
Coordinates with external contacts	❌	✅
Group scheduling (3+ people)	❌	✅
Parses screenshots and PDFs	❌	✅
Sends follow-up emails	❌	✅
Works via text message	❌	✅
Available now (no waitlist)	Varies	✅
Requires opening an app	✅	❌

The bottom line: Native AI helps you manage your calendar. Carly helps you coordinate with other people—which is where scheduling actually gets hard.

How to Get the Most from Your Calendar’s AI

While native AI has limitations, you can still maximize what it offers.

Best Practices for Google Calendar AI

Keep your calendar accurate: AI can only suggest free times based on what’s actually on your calendar. If you have commitments that aren’t logged, the AI will suggest those times.

Use specific prompts: Instead of “find me time next week,” try “find 30 minutes between 2pm and 5pm on Tuesday or Wednesday.” Specific requests get better results.

Enable Workspace extensions: If you’re on Google Workspace, enable Gemini extensions to give AI access to more context from Drive and other apps.

Use “Help me schedule” in Gmail: When responding to meeting requests, use this feature rather than switching to Calendar separately.

If you need to share your calendar with colleagues, here’s our guide to share your Google Calendar properly.

Best Practices for Outlook Copilot

Verify your Copilot license: Copilot features require a Microsoft 365 Copilot license. Check with your IT admin if features seem missing.

Use meeting prep before important calls: Let Copilot summarize relevant emails and documents so you walk into meetings informed.

Try targeted release features: Opt into Microsoft’s targeted release program to get new Copilot features before general availability.

For Outlook users who need to share availability, check out how to share your Outlook calendar.

Calendar Management Beyond AI

The top performers we studied don’t rely on AI to make their calendars work. They use systems: protected blocks for deep work, themed days, ruthless meeting filters.

AI is a tool, not a strategy. Use it to save time on the mechanical parts of scheduling, but don’t outsource your calendar strategy to an algorithm.

When to Consider Third-Party Tools

Native AI features handle simple, internal scheduling well. But if you’re regularly dealing with complex scheduling scenarios, you need something purpose-built for coordination.

Common reasons people look beyond native AI:

• Scheduling links feel impersonal—you want natural email conversations instead (here’s a Calendly alternative that doesn’t require links)
• AI calendar apps like Motion are too complex to learn (see this Motion alternative)
• Need to coordinate across Google, Outlook, and Apple calendars
• Want scheduling handled without opening any app at all
• Tired of copying flight confirmations and event details manually

The average professional spends 4.8 hours per week on meeting logistics. Native AI might cut that by 20-30%. Carly can cut it by 80%+ because she handles the parts that take the most time: coordinating with other people, following up, and processing the random emails and screenshots that contain your schedule.

The Bottom Line

Google Calendar AI features and Outlook Copilot are genuinely useful for basic tasks. They make it faster to create events, find free times, and manage your own schedule.

Google’s new CC agent is an interesting experiment that proves email-based AI assistants are what users want. But CC summarizes rather than schedules—a frustrating limitation.

The limitations of native AI are real:

• Only work within their ecosystems (Google or Microsoft, not both)
• Can’t coordinate with external contacts
• Limited to 1:1 scheduling
• No image or itinerary processing
• Require being in the app (except CC, which doesn’t actually schedule)

For simple scheduling within your organization, native AI is a solid choice. For everything else—external contacts, group scheduling, processing travel confirmations, zero-friction workflow—you need Carly.

The way scheduling should work: Forward an email. Send a text. That’s all it takes.
