In plain words
Alexa is an assistant you talk to, made by Amazon. It lives in Echo smart speakers, Fire TV, the Alexa phone app and other gadgets. You say "Alexa" and then ask for the weather, a song, a timer, or to switch off the lights.
The first Alexa, from 2014, was good at fixed commands. It recognised what you said and matched it to a skill it already knew. Ask something it was not built for and it often gave up.
Alexa+ is the new version, rebuilt on large language models, the same kind of AI behind chatbots. It can hold a back-and-forth conversation, remember context and take actions on websites and services for you, such as booking a repair. It is an AI assistant you mostly use by voice.
Everyday example
A helper at home who knows your house
Imagine telling a helper at home: "It's getting dark, and remind me to call Didi after dinner." A good helper switches on the lights, notes the reminder and says "done". You did not name the lamp or set a time. Alexa+ tries to work like that: it turns loose everyday speech into concrete actions, then confirms out loud.
Where the example breaks: A real helper understands your family and your mood. Alexa can mishear, misread what you meant or act on the wrong device, and it only knows what its connected apps and devices tell it.
How it actually works
Each request goes through the same few steps, most of them in Amazon's cloud.
Wake word on the device
The speaker listens locally for the word "Alexa". Only after hearing it does it send your request to Amazon's servers, where most of the work happens.
Speech becomes text
Speech recognition turns your voice into words. It has to cope with accents, noise and people switching languages mid-sentence, as many Indian families do with Hindi and English.
A model decides what to do
In Alexa+, a large language model reads the request along with context such as your devices and recent conversation. Amazon says it is model agnostic: it routes each request to the model it judges best, including Amazon's own Nova models and Anthropic's Claude.
It acts, then speaks
The model can call connected services, a form of tool use: smart lights, music, shopping, booking sites. The reply is turned back into a voice with text to speech.

Questions people ask
What is the difference between Alexa and Alexa+?
Alexa+ is the upgraded Alexa built on large language models. The original handled set commands well but struggled with anything unexpected. Alexa+ can follow a conversation, understand loose requests and complete tasks across websites and services. It works on most of the same Echo devices.
Is Alexa a chatbot?
Alexa+ works much like one, mainly by voice. Like a chatbot, it runs on large language models and replies in conversation. It is also tied to your devices and Amazon services, so it is built to do things, not only talk. You can also type to it in a browser on Alexa.com.
Does Alexa listen to everything I say?
Amazon says Echo devices record only after detecting the wake word, spotted on the device itself, and then send the request to its cloud. Mistaken wake-ups do happen. Amazon also says you can review and delete recordings in the Alexa app, and every Echo has a microphone off button.
Is Alexa+ available in India?
Yes, in early access, from 16 September 2026, in Hindi and English, and you can mix the two mid-sentence. Amazon says it stays free for Prime members after early access. Countries and terms change often.
What AI model does Alexa use?
More than one. Amazon describes Alexa+ as model agnostic: it picks a model for each request from those on Amazon Bedrock, its cloud AI service. These include Amazon's own Nova models and Anthropic's Claude models.
