Siri vs Alexa: A Detailed Comparison 2024

In 2024, the two most popular virtual assistants are Siri by Apple and Alexa by Amazon. Both have been around for years and have continued improving with more features and capabilities. But how exactly do they compare in 2024? Which one is better for your needs?

Siri vs alexa

Overview of Siri and Alexa

Siri was first launched in 2011 as a virtual assistant integrated into Apple products like the iPhone and iPad. Over the years, Siri has expanded to the Mac, Apple Watch, HomePod and more. Siri responds to voice commands to do things like place calls, send messages, give directions, set reminders, get answers from the web, and control smart home devices.

Alexa was launched by Amazon in 2014. Alexa powers Amazon’s line of Echo smart speakers and displays and is also integrated into products like Fire TV and Fire tablets. Like Siri, Alexa responds to voice commands to perform various tasks such as streaming music, controlling smart home devices, online shopping with Amazon, setting timers and alarms, getting news updates, and more.

Privacy and Security

Privacy and security is an important consideration when choosing a virtual assistant platform in 2024. There have been some concerns over the years about how much personal data Siri and Alexa collect and whether that data is sufficiently protected.

Apple touts that privacy is a fundamental human right. For Siri requests, Apple claims audio recordings are not linked to an individual’s Apple ID. For personalized Siri data like contacts or calendars, Apple allows users to turn off Siri’s access or delete data associated with an account. Overall, Apple’s privacy policies for Siri seem geared towards collecting as little personal data as possible.

Amazon has faced more scrutiny over Alexa privacy policies over the years. Users can now opt out of Amazon saving Alexa voice recordings or have recordings automatically deleted. But other concerns remain about the vast amount of data Amazon can access to continually improve the Alexa AI. Amazon does provide tools like Alexa Privacy Zones, shopping PIN codes, and ways to view or delete your Alexa history and skills data.

Features and Performance

Siri and Alexa have matured considerably since first launching. But Alexa has consistently been better at understanding natural language requests and actually performing what’s asked compared to Siri, based on comprehensive third party testing over the years.

Siri Features

Siri is tightly integrated into Apple’s products and ecosystem. Siri’s strengths are more apparent when using a combination of iOS, iPadOS, macOS, watchOS and tvOS devices. For example, Siri can seamlessly hand off tasks between an iPhone, iPad and HomePod for continuity. Siri offers all the usual virtual assistant staples like scheduling meetings or appointments, setting timers and alarms, placing calls or FaceTime video calls, texting or messaging contacts, creating calendar events or reminders, checking weather, traffic, sports scores or other information, controlling music playback, and launching apps.

Siri also excels at controlling HomeKit enabled smart home devices like lights, smart locks, thermostats, blinds and more using just your voice. Siri makes interacting with smart homes extremely convenient. However, Siri continues to struggle with more advanced or nuanced requests compared to Alexa. Interacting with Siri can often feel rigid as the available voice commands are limited unless speaking requests in just the right way.

Alexa Features

The greatest strength for Alexa is the gigantic knowledge graph Amazon has built with vast connections between entities spanning people, places, events plus products and services. This allows Alexa to pull useful tidbits to create informative responses not possible with Siri in many cases.

Some examples of Alexa’s more powerful abilities in 2024 include:

  • Better at answering random trivia questions correctly
  • Detailed sports scores, statistics player/team profile lookups
  • Accurate responses to questions about celebrities, movies, music
  • Can recommend products to purchase within Amazon’s catalog
  • Order food delivery with integrated skills like Domino’s
  • Book Uber/Lyft rides to destinations
  • Listen to Audible audiobooks
  • Interact with tens of thousands of third-party skills

Alexa is fantastic for households fully bought into the Amazon /Alexa ecosystem. Alexa makes it extremely convenient to shop on Amazon or interact with other Amazon services hands free.

But users more embedded in Apple’s ecosystem may be disappointed by Alexa’s inability to directly control or access Apple services. Siri has special integrations with Apple Music, Apple TV+, Apple Podcasts, Find My tracking, iCloud syncing across devices, and more unmatched by Alexa.

Smart Home Control

Both Siri and Alexa offer robust smart home platforms for controlling Internet connected devices like lights, plugs, locks, thermostats, security cameras and appliances using voice commands.

Apple has HomeKit. Amazon offers the Alexa Smart Home platform. They take different approaches but achieve much of the same end result of unifying many brands of devices under one system.

Here’s how Siri and Alexa compare when it comes to controlling smart devices in 2024:

Siri via HomeKit probably offers smarter automation capabilities overall like triggering scenes or actions based on people arriving or leaving the home. Alexa Guard focuses more on traditional security use cases like receiving motion alerts when away.

But Alexa ties into an order of magnitude more smart products given Amazon’s open ecosystem approach. Support for niche brands and devices is far superior with Alexa. For serious smart homes with lots of devices, Alexa may provide wider compatibility. But Siri offers incredibly tight and convenient integration if already invested into the Apple ecosystem.

Music and Entertainment

Music is central to interacting with voice assistants. Both Siri and Alexa allow requesting songs or playlists, controlling playback, looking up artist or album info, and more.

Siri’s deep integration with Apple Music gives a more feature rich experience for subscribers to Apple’s streaming service. Support for iOS features like spatial Dolby Atmos Audio and offline downloads are Siri strengths with Apple Music. Alexa offers comparable playback controls and music requests across a broader range of providers – Amazon Music, Apple Music, Spotify, Pandora, SiriusXM, Deezer, and more. Alexa also ties into additional entertainment options like checking movie showtimes, Audible book playback, and Alexa skills that feel more entertainment focused.

Which assistant provides better entertainment integration depends much on which music or media ecosystems you are invested into in 2024. Both provide plenty of flexibility here even if Siri has a noticeable Apple Music focus while Alexa aims to complement Amazon’s content.


A key advantage for Siri over Alexa is mobility from deep integration with Apple’s mobile products running iOS or iPadOS. Siri is readily available on iPhones, iPads, AirPods or Apple Watch without additional accessories needed. Alexa originated on the Echo smart speakers. So Alexa still works best as a stationary assistant accessed via Echo devices or other Alexa enabled speakers. There are ways to bring Alexa on the go on mobile devices or earbuds. But the experience feels kludged together rather than seamlessly mobile like with Siri.

The mobility of Siri allows convenient hands free use while driving for directions or music playback. Quick access is there for PAs while walking or working. This advantage may diminish over time if Amazon further optimizes Alexa for mobile use cases. But for now in 2024, Siri excels for an assistant on the go versus Alexa’s superior performance as an always listening stationary assistant.

In 2024, both Siri and Alexa provide robust voice assistant capabilities with some feature overlap but also key differences that make them shine in different usage scenarios. Siri delivers unrivaled convenience, mobility, and privacy protection within the Apple ecosystem. Performance deficiencies compared to Alexa are compensated somewhat by Siri’s iOS integrations and seamless device handoffs. HomeKit also offers excellent smart home control for the Apple faithful.

Meanwhile, Alexa leverages Amazon’s vast data and immense catalog to enable more powerful assisted experiences. Alexa feels like the more skilled assistant for households embracing an Amazon centric lifestyle. From shopping to entertainment and standalone Echo devices, Alexa pushes forward voice UIs. But there are some nagging privacy concerns with Amazon’s data collection practices to consider. For most consumers debating between assistants, choose the ecosystem that best fits your lifestyle.


What are Siri Shortcuts and do Alexa Routines compare?

Siri Shortcuts allow users to create customized voice commands to have Siri complete multi step actions like sending a message, getting directions, or playing a playlist with just one request. Alexa Routines offer similar multi action automation capabilities but with less flexibility than Shortcuts provide.

Can Siri or Alexa understand commands in multiple languages?

Both assistants offer some form of multilingual support. Siri supports over 20 languages including variants for region specific dialects. Alexa has the edge currently with support for English alongside eight other languages: Spanish, Japanese, Brazilian Portuguese, French Canadian, German, Hindi, Italian and Spanish for US.

What iOS or Android devices support using Siri or Alexa natively?

All iOS and iPadOS devices fully support Siri access, especially useful on iPhone and iPad. Only Amazon’s Fire tablets allow hands free Alexa without additional accessories. Android phones take extra steps to enable either assistant. But Alexa generally has better Android integration through the Alexa app.

Which smart home platform works with more third-party products – Apple HomeKit or Amazon Alexa?

Alexa Smart Home supports over 100,000 compatible devices which dwarfs HomeKit’s 500+ supported products. Alexa’s open approach encourages broad device compatibility. HomeKit relies on official licensing partnerships so hardware support is slower growing.

Can Siri or Alexa provide notifications or share data and integrations across devices?

Unique to Apple, Siri can communicate between any iOS, iPad OS or macOS devices thanks to the company’s tight ecosystem integration via iCloud syncing. Alexa lacks comparable multi device communications but enables household members to access the same Alexa account.
