Amazon Lex Getting Started
AWS Skill Builder
Last updated February 23, 2026
Amazon Lex Getting Started is a free, one-hour introduction to Amazon Lex, AWS's managed service for building conversational interfaces — the chatbots and voice assistants people interact with in plain language. Lex uses natural language models to handle the design, building, testing, and deployment of these interfaces for both voice and text. The course covers the service essentials — how it works, its benefits, typical use cases, technical concepts, and cost — and reviews an architecture that combines Lex with other AWS offerings to build a chatbot solution. It then turns hands-on: a guided tutorial walks you through creating an Amazon Lex bot in your own AWS account using the visual builder, then removing it afterward.

- What Lex is and how it builds voice/text conversational interfaces
- Benefits, use cases, technical concepts
- Chatbot solution architecture (Lex + other AWS services)
- Cost structure

Why we suggest this course
It goes past describing conversational AI to having you build a bot in the visual builder, which is where the work of designing a conversation — rather than just understanding the idea of one — becomes concrete. One thing to know: this is an introduction to a single AWS service, so it is vendor-specific by design — you are learning Amazon Lex in particular, not chatbot design in general, though the underlying idea of building a conversational interface from natural language carries across other tools.
