The Text Difficulty Converter is an AI-powered web application designed to adjust the readability of text based on user-defined proficiency levels, ranging from A1 to C2. This tool simplifies or complicates written content by restructuring text to meet specific challenges, making it suitable for a variety of audiences. It supports multiple input sources, including PDFs, and utilizes advanced GPT models like gpt-4o-mini and gpt-4-turbo, ensuring high-quality text modifications.

In addition to text conversion, the application features a Text to Audio function that allows users to convert written content into spoken words. Users can choose from several text-to-speech models and voice options, such as Alloy and Nova, to personalize their audio experience. The generated audio can be listened to in segments or as a whole, with the option to download files for offline use. An OpenAI API Key is required to utilize both functionalities.
