+# QwenScope Feature Explorer
+
+Interactive Sparse Autoencoder (SAE) feature exploration and steering demo for Qwen3.5-2B, powered by Hugging Face ZeroGPU.
+
+## Features
+
+- **Feature Comparison**: Compare SAE feature activations between two text examples across all transformer layers.
+- **Feature Steering**: Inject SAE decoder vectors into the residual stream to steer model generation behavior.
