+This CLI tool runs `git diff` to grab all your latest code changes, sends them to your selected AI provider (Groq, OpenAI, or Anthropic), then returns the AI generated commit message.
 
-The tool uses Groq's fast inference API to provide quick and accurate commit message suggestions based on your code changes.
+The tool supports multiple AI providers:
+- **Groq**: Fast inference API with open models for quick commit message generation
+- **OpenAI**: Access to GPT models for advanced language understanding
+- **Anthropic**: Claude models with excellent context understanding and nuanced responses
 
 ### Large diff handling
 
@@ -348,9 +406,12 @@ If you get a 413 error, your diff is too large for the API. Try these solutions:
 - Lower generate count: `lazycommit config set generate=1` (default)
 - Reduce timeout: `lazycommit config set timeout=5000` for faster failures
 
-## Why Groq?
+## Why Multiple Providers?
 
-- **Fast**: Groq provides ultra-fast inference speeds, especially with the 8B instant model
+- **Flexibility**: Choose between Groq's fast inference, OpenAI's advanced GPT models, or Anthropic's Claude models
+- **Cost Control**: Select the provider that fits your budget
+- **Availability**: Switch providers if one experiences downtime
+- **Quality**: Different models excel at different types of commits
 - **Cost-effective**: More affordable than traditional AI APIs
 - **Open source models**: Uses leading open-source language models
 - **Reliable**: High uptime and consistent performance
