KallyAI vs Siri with Apple Intelligence: AI Executive Assistant vs Voice Assistant (2026)

Apple just partnered with Google to bring Gemini 2.5 Pro to Siri in iOS 26.4. It's a massive upgrade—8x more processing power, better context awareness, faster responses. But does it make Siri an AI executive assistant? Not even close. Here's the difference.

The fundamental difference: executing tasks vs controlling your device

KallyAI is an AI executive assistant that executes real-world tasks on your behalf. You describe what you need—"get quotes from three plumbers, compare their availability, and email me a summary"—and KallyAI handles the entire workflow. It makes phone calls, sends emails, researches options, coordinates across channels, and delivers results with full transcripts and proof. You approve the plan before it acts.

Siri with Apple Intelligence is a voice assistant deeply integrated into your iPhone, iPad, and Mac. With the Gemini upgrade in iOS 26.4, Siri gets dramatically better at understanding complex requests, recognizing screen content, and controlling device features. It can initiate a phone call, send a text, toggle settings, and search the web—all faster and more naturally than before.

The difference? KallyAI executes entire workflows in the real world. Siri helps you interact with your device. One is an executive assistant. The other is a smart remote control.

What KallyAI actually does (beyond calls)

KallyAI isn't a phone call tool. It's an AI executive assistant that handles complex, multi-step tasks across multiple channels:

• Phone calls: Makes outbound calls, navigates IVR menus, waits on hold, has full conversations with businesses, receives inbound calls on your behalf
• Email: Sends follow-up emails after calls, tracks responses, handles email threads with businesses and vendors
• Research: Finds options, compares prices, gathers information across sources, delivers organized summaries
• Multi-step coordination: Chains actions together—"call 3 dentists, compare availability, book the earliest, and email me a confirmation" is a single task
• Proof and transcripts: Every call transcribed, every email logged, every action documented

You describe the goal. KallyAI figures out the steps, shows you a plan, and executes it across whatever channels are needed.

The Gemini upgrade: what actually changes in iOS 26.4

With iOS 26.4 (rolling out March–April 2026), Siri gets Google's Gemini 2.5 Pro under the hood. Here's what actually changes:

• Smarter understanding: Complex instruction success jumps from 58% to 92%. Multi-step device commands like "turn on Do Not Disturb and text Sarah I'm in a meeting" actually work reliably.
• Faster responses: Under 0.5 seconds—twice as fast as current Siri.
• Screen awareness: Siri can see what's on your screen and act on it.
• Personal context: Better at finding specific files, messages, and calendar events.
• Multi-modal: Can analyze images and visual content.

These are real improvements for a device assistant. But Siri's "multi-step" means chaining device actions (set timer + send text). KallyAI's "multi-step" means executing an entire workflow across phone, email, and research that might take a human assistant hours.

The full chatbot experience (codenamed "Campos") is planned for iOS 27 in September 2026—but even that focuses on conversational AI within your device, not executing tasks in the real world on your behalf.

Pricing comparison

KallyAI pricing

Credits cover all actions: calls (~6/min), emails (~0.25 each), research included. A typical appointment booking costs 30–40 credits. Annual plans save 20%.

Siri with Apple Intelligence pricing

Siri is free but can't execute tasks for you. KallyAI costs money but replaces hours of administrative work—calls, emails, research, and coordination. A human executive assistant costs $50,000–$100,000/year. KallyAI starts at $228/year.

Real-world scenarios: which tool wins?

Get quotes from 3 vendors and compare them

KallyAI wins. "Get bulk pricing from these 3 suppliers for 500 units and email me a comparison." KallyAI calls each vendor, asks the right questions, compiles the results, and emails you a summary. This is a multi-step workflow across calls, research, and email. Siri can't even begin this task.

Schedule a dentist appointment

KallyAI wins. "Book a dentist appointment with Dr. Smith for next week, mornings preferred, and email me the confirmation." KallyAI calls the office, navigates the IVR, books the slot, and sends you a transcript plus email confirmation. With Siri: "Hey Siri, call Dr. Smith's office"—then you handle the call yourself.

Research and book a hotel for a trip

KallyAI wins. "Find hotels near the conference center in Austin under $200/night, check availability for March 15-18, and book the best-reviewed one." KallyAI researches options, calls hotels for availability, compares, and handles the booking. Siri can search the web but won't execute the rest.

Follow up with a contractor who hasn't responded

KallyAI wins. "Email the contractor about the quote, and if no response by tomorrow, call them." KallyAI sends the email, monitors for a response, and escalates to a phone call if needed. This kind of conditional, multi-channel coordination is exactly what an executive assistant does.

Set a timer and toggle Do Not Disturb

Siri wins. "Set a timer for 10 minutes and turn on Do Not Disturb." Done instantly, hands-free. KallyAI doesn't control your device.

Send a quick text while driving

Siri wins. Voice-activated, hands-free, integrated with your contacts. KallyAI requires a browser.

Find a specific photo from last vacation

Siri wins. With Gemini-powered screen awareness and personal context, Siri can search your photos by description. KallyAI doesn't access your device files.

What Siri still can't do (even with Gemini)

Even with Gemini 2.5 Pro, Siri remains a device assistant—brilliant at controlling your Apple ecosystem. But it can't act as an executive assistant:

• Have full conversations with businesses on your behalf (phone or email)
• Execute multi-step workflows across phone, email, and research
• Navigate IVR phone trees or wait on hold
• Send emails to businesses or vendors on your behalf
• Research options, compare quotes, and deliver organized summaries
• Handle conditional logic ("if no response, then call them")
• Receive and handle inbound calls for you
• Provide transcripts and proof of completed tasks

Apple's roadmap for iOS 27 includes a full chatbot experience, but the focus is conversational AI with you—not executing tasks for you in the real world. Device intelligence and task execution are fundamentally different product categories.

When to choose each

Use Siri when:

• You need quick device control (timers, settings, messages)
• You want hands-free information lookup
• You're initiating a call you'll handle yourself
• You need on-device, privacy-first AI assistance
• The task lives within your Apple ecosystem

Use KallyAI when:

• You have administrative tasks you want fully delegated
• The task involves calls, emails, research, or any combination
• You need multi-step coordination across channels
• You want transcripts and proof of every interaction
• You've been putting off tasks because they involve too many steps

Use both:

Siri manages your device and daily routine. KallyAI handles the administrative workflows—calls, emails, research, and coordination—that you'd otherwise spend hours on. They solve completely different problems.

Frequently Asked Questions

Can Siri handle tasks like calling businesses, sending emails, or doing research with Apple Intelligence?

No. Even with the Gemini upgrade in iOS 26.4, Siri can initiate a call or draft a message, but cannot execute multi-step workflows on your behalf. It won't call a business, have the conversation, then email you a summary. KallyAI handles the entire workflow—calls, emails, research, and coordination—and delivers results with proof.

What does the Gemini upgrade change for Siri?

iOS 26.4 brings Google Gemini 2.5 Pro to Siri, improving complex instruction understanding (58% to 92% success rate), halving response times, adding screen awareness, and enabling better personal context. It makes Siri a much better device assistant, but does not add task execution capabilities like making calls on your behalf, sending emails to businesses, or handling multi-step coordination.

Is KallyAI available on iPhone?

Yes. KallyAI works in any browser, including Safari on iPhone. No app download required. You describe your task, approve the plan, and KallyAI handles the rest—whether that involves calls, emails, research, or all three.

Should I use KallyAI or Siri?

Use both. Siri excels at device control, quick lookups, and hands-free commands. KallyAI handles administrative tasks you want fully delegated—phone calls, email follow-ups, vendor research, multi-step coordination. They solve completely different problems.

Will Siri eventually replace KallyAI?

Apple's iOS 27 roadmap includes a chatbot experience, but the focus is conversational AI with you—not executing tasks on your behalf in the real world. Autonomously calling businesses, sending coordinated emails, researching options, and handling multi-step workflows is a fundamentally different product category than a device assistant.
