+# Handwritten Text Recognition Model
+
+This code creates a Handwritten Text Recognition app using Machine Learning.
+
+The app provides two main functionalities
+
+1. Draw: Users can draw on a canvas, and the app will detect and display any text from the drawing.
+2. Upload Image: Users can upload an image, and the app will detect and display any text present in the uploaded image.
+
+

+## Tech Stack
+
+**Languages:** Python
+
+**Libraries:** easyocr, opencv, numpy, scipy etc
+
+**Framework:** Streamlit
