+## What is Alan?
+
+Alan is a conversational AI platform that lets you build voice assistants, chatbots and conversational bots for your business from scratch. It offers the whole set of tools to design, embed and host a voice interface solution for your app:
+
+* [Alan Studio](https://studio.alan.app/) — a web portal where you can create and manage a dialog scenario for the conversational assistant or chatbot
+* [Voice SDKs](https://github.com/alan-ai) to embed the Alan voice to applications running on multiple platforms, both web and mobile
+* Alan Cloud — Alan's AI-backend that hosts and runs voice scripts, and accomplishes all Spoken Language Understanding (SLU) and Natural Language Processing (NLP) tasks
+
+To enable voice control in your app, Alan leverages its NLP-powered engine with industry’s best Automatic Speech Recognition and Speech Synthesis tools and methods. There is no need to create datasets or train your voice solution on your own: Alan automatically trains on voice commands using your app’s terms.
