Alexa is the cloud-based voice assistant and family of smart-speaker, display, and wearable devices launched by πAmazon in November 2014 alongside the original Amazon Echo, combining a far-field microphone array with Alexa's cloud-side natural-language model and third-party "Skills" to handle voice commands across consumer hardware.
Over the following decade Alexa expanded from a single tabletop speaker into a multi-product family β Echo Dot, Echo Show, Echo Studio, Echo Auto, Echo Frames, Fire TV remote integration, and a long tail of partner-built Alexa Built-in devices β while the underlying assistant became Amazon's primary surface for voice-driven shopping, smart-home control, third-party Skills, and household routines. In early 2025 Amazon launched Alexa+, a generative-AI overhaul of the assistant built on the company's Nova foundation models (with optional Anthropic Claude backstops) and positioned as a paid subscription layer atop the original free Alexa for richer conversational, agentic, and multi-step task behavior. Alexa-branded products remain among the most widely deployed consumer voice interfaces in North America despite an uneven history of profitability inside Amazon's devices organization.
