 The AI Toolkit is a set of AI chat-related widgets to make it easy to add an AI chat window to your Flutter app. The AI Toolkit is organized around an abstract LLM provider API to make it easy to swap out the LLM provider that you'd like your chat provider to use. Out of the box, it comes with support for two LLM provider integrations: Google Gemini AI and Firebase Vertex AI.
 
-## Current Alpha Features
-The AI Toolkit is currently under active development and at the alpha stage, with the following features currently available:

-If you like, use your Firebase project with the <a href="https://github.com/csells/flutter_ai_toolkit/blob/main/example/lib/vertex/vertex.dart">vertex.dart</a> sample. This sample has also been tested on Android, iOS, the web and macOS.

 Note: There's no API key; Firebase manages all of that for you in the Firebase project. However, in the same way that someone can reverse engineer the Gemini API key out of your Flutter code, they can do that with your Firebase project ID and related settings. To guard against that, check out [Firebase AppCheck](https://firebase.google.com/learn/pathways/firebase-app-check), which is beyond the scope of the sample code in this project.
 
-## More Features Coming Soon!
-As I mentioned, the AI Toolkit is just in the alpha phase of it's lifetime and it's under active development. Coming soon, you should expect the following features:
-- stand-alone chatbot app sample with multi-session support
-- thoroughly tested multi-platform support, including Windows and Linux
