 # @push.rocks/smartai
-a standardized interface to talk to AI models
+
+Provides a standardized interface for integrating and conversing with multiple AI models, supporting operations like chat and potentially audio responses.
 
 ## Install
-To install `@push.rocks/smartai`, run the following command in your terminal:
+
+To add @push.rocks/smartai to your project, run the following command in your terminal:
+
 ```bash
 npm install @push.rocks/smartai
 ```
 
-This will add the package to your project's dependencies.
+This command installs the package and adds it to your project's dependencies.
 
 ## Usage
 
-In the following guide, you'll learn how to leverage `@push.rocks/smartai` for integrating AI models into your applications using TypeScript with ESM syntax.
+The `@push.rocks/smartai` package is a comprehensive solution for integrating and interacting with various AI models, designed to support operations ranging from chat interactions to possibly handling audio responses. This documentation will guide you through the process of utilizing `@push.rocks/smartai` in your applications, focusing on TypeScript and ESM syntax to demonstrate its full capabilities.
 
 ### Getting Started
 
-First, you'll need to import the necessary modules from `@push.rocks/smartai`. This typically includes the main `SmartAi` class along with any specific provider classes you intend to use, such as `OpenAiProvider` or `AnthropicProvider`.
+Before you begin, ensure you have installed the package in your project as described in the **Install** section above. Once installed, you can start integrating AI functionalities into your application.
+
+### Initializing SmartAi
+
+The first step is to import and initialize the `SmartAi` class with appropriate options, including tokens for the AI services you plan to use:
 
 ```typescript
-import { SmartAi, OpenAiProvider, AnthropicProvider } from '@push.rocks/smartai';
-```
+import { SmartAi } from '@push.rocks/smartai';
 
-### Initialization
-
-Create an instance of `SmartAi` by providing the required options, which include authentication tokens for the AI providers you plan to use.
-
-```typescript
 const smartAi = new SmartAi({
-  openaiToken: 'your-openai-token-here',
-  anthropicToken: 'your-anthropic-token-here'
+  openaiToken: 'your-openai-access-token',
+  anthropicToken: 'your-anthropic-access-token'
 });
+
+await smartAi.start();
 ```
 
-### Creating a Conversation
+### Creating Conversations with AI
 
-`@push.rocks/smartai` offers a versatile way to handle conversations with AI. To create a conversation using OpenAI, for instance:
+`SmartAi` provides a flexible interface to create and manage conversations with different AI providers. You can create a conversation with any supported AI provider like OpenAI or Anthropic by specifying the provider you want to use:
 
 ```typescript
-async function createOpenAiConversation() {
-  const conversation = await smartAi.createOpenApiConversation();
-}
+const openAiConversation = await smartAi.createConversation('openai');
+const anthropicConversation = await smartAi.createConversation('anthropic');
 ```
 
-For Anthropic-based conversations:
+### Chatting with AI
+
+Once you have a conversation instance, you can start sending messages to the AI and receive responses. Each conversation object provides methods to interact in a synchronous or asynchronous manner, depending on your use case.
+
+#### Synchronous Chat Example
+
+Here's how you can have a synchronous chat with OpenAI:
 
 ```typescript
-async function createAnthropicConversation() {
-  const conversation = await smartAi.createAnthropicConversation();
-}
+const response = await openAiConversation.chat({
+  systemMessage: 'This is a greeting from the system.',
+  userMessage: 'Hello, AI! How are you today?',
+  messageHistory: [] // Previous messages in the conversation
+});
+
+console.log(response.message); // Log the response from AI
 ```
 
-### Advanced Usage: Streaming and Chat
+#### Streaming Chat Example
 
-Advanced use cases might require direct access to the streaming APIs provided by the AI models. For instance, handling a chat stream with OpenAI can be achieved as follows:
-
-#### Set Up the Conversation Stream
-
-First, create a conversation and obtain the input and output streams.
+For real-time, streaming interactions, you can utilize the streaming capabilities provided by the conversation object. This enables a continuous exchange of messages between your application and the AI:
 
 ```typescript
-const conversation = await smartAi.createOpenApiConversation();
-const inputStreamWriter = conversation.getInputStreamWriter();
-const outputStream = conversation.getOutputStream();
-```
+const inputStreamWriter = openAiConversation.getInputStreamWriter();
+const outputStream = openAiConversation.getOutputStream();
 
-#### Write to Input Stream
+inputStreamWriter.write('Hello, AI! Can you stream responses?');
 
-To send messages to the AI model, use the input stream writer.
-
-```typescript
-await inputStreamWriter.write('Hello, SmartAI!');
-```
-
-#### Processing Output Stream
-
-Output from the AI model can be processed by reading from the output stream.
-
-```typescript
 const reader = outputStream.getReader();
-reader.read().then(function processText({ done, value }) {
+reader.read().then(function processText({done, value}) {
   if (done) {
-    console.log("Stream complete");
+    console.log('Stream finished.');
     return;
   }
-  console.log("Received from AI:", value);
-  reader.read().then(processText);
+  console.log('AI says:', value);
+  reader.read().then(processText); // Continue reading messages
 });
 ```
 
-### Handling Audio
+### Extending Conversations
 
-`@push.rocks/smartai` also supports handling audio responses from AI models. To generate and retrieve audio output:
-
-```typescript
-const tts = await TTS.createWithOpenAi(smartAi);
-```
-
-This code snippet initializes text-to-speech (TTS) capabilities using the OpenAI model. Further customization and usage of audio APIs will depend on the capabilities offered by the specific AI model and provider you are working with.
+The modular design of `@push.rocks/smartai` allows you to extend conversations with additional features, such as handling audio responses or integrating other AI-powered functionalities. Utilize the provided AI providers' APIs to explore and implement a wide range of AI interactions within your conversations.
 
 ### Conclusion
 
-`@push.rocks/smartai` offers a flexible and standardized interface for interacting with AI models, streamlining the development of applications that leverage AI capabilities. Through the outlined examples, you've seen how to initialize the library, create conversations, and handle both text and audio interactions with AI models in a TypeScript environment following ESM syntax.
-
-For a comprehensive understanding of all features and to explore more advanced use cases, refer to the official [documentation](https://code.foss.global/push.rocks/smartai#readme) and check the `npmextra.json` file's `tsdocs` section for additional insights on module usage.
+With `@push.rocks/smartai`, integrating AI functionalities into your applications becomes streamlined and efficient. By leveraging the standardized interface provided by the package, you can easily converse with multiple AI models, expanding the capabilities of your applications with cutting-edge AI features. Whether you're implementing simple chat interactions or complex, real-time communication flows, `@push.rocks/smartai` offers the tools and flexibility needed to create engaging, AI-enhanced experiences.
