What Siri is best at

~30s

Siri excels at tasks that are tightly connected to your Apple devices and apps. Best uses: "Hey Siri, call Dad" (uses your iPhone contacts seamlessly), "Hey Siri, set a reminder for my dentist appointment Thursday at 2 PM" (adds to your iPhone Reminders), "Hey Siri, read my last text from Mom" (reads and replies to iMessages), "Hey Siri, turn on Do Not Disturb" (controls iPhone settings), "Hey Siri, navigate home" (opens Apple Maps). Siri is the right choice when you want to control your iPhone or interact with Apple apps hands-free.

What Google Assistant is best at

~30s

Google Assistant leads at information retrieval and search — it has access to Google's entire search knowledge. Best uses: "Hey Google, what's in the news today?" (comprehensive news summaries), "Hey Google, what restaurants near me are open right now?" (accurate, up-to-date business info), "Hey Google, how far is it from here to Boston?" (precise directions and traffic), "Hey Google, what are the side effects of lisinopril?" (detailed health information), "Hey Google, translate 'where is the pharmacy' into Spanish." Google Assistant is the right choice when you need accurate information quickly.

What Alexa is best at

~27s

Alexa shines at smart home control and Echo device tasks. Best uses: "Alexa, turn off the living room lights" (most smart home devices work natively with Alexa), "Alexa, add milk to my shopping list" (creates a shared Amazon shopping list), "Alexa, set a 15-minute timer" (perfect for cooking), "Alexa, what's the weather this week?" (quick, no-screen weather info), "Alexa, play some soft jazz" (best music integration with Amazon Music and Spotify). Alexa is the right choice for smart home control and Amazon shopping.

Use more than one — they all have their place

~29s

Most people use multiple voice assistants without even thinking about it. An iPhone user might say "Hey Siri, call Mom" from their phone, then "Hey Google" on their smart speaker for a news briefing, then "Alexa" to control their smart lights. There is no need to choose just one. A practical tip: if you ask one voice assistant a question and get a bad answer, try asking Google directly — it tends to have the most comprehensive and current information for factual questions.
