"The Text Difficulty Converter is an AI-powered tool designed to optimize the readability of written content by adjusting its complexity. With an adjustable difficulty setting, users can select from a range of proficiency levels, spanning from A1 to C2. Once a desired level is chosen, the tool restructures the text to match the targeted reading difficulty, allowing for either simplification or increased complexity depending on the user’s needs. This tool supports text conversions from various sources, including PDFs, and is powered by advanced GPT models like gpt-4o-mini, gpt-4-turbo, and gpt-4o, ensuring precise and efficient adjustments. Another key feature is the Text-to-Audio conversion, which enables users to transform text into speech. Users can select from a variety of text-to-speech models and voices to generate audio files, which can be listened to in segments or in full. Additionally, the tool provides the option to download these audio files for offline use. Voice options include Alloy, Echo, Fable, Onyx, Nova, and Shimmer, giving users flexibility in choosing the best audio output for their needs. Both tools require an OpenAI API Key for access. This SEO-optimized version integrates relevant keywords like ""AI-powered text converter,"" ""text-to-speech tool,"" ""GPT models,"" and ""downloadable audio files"" to enhance search engine visibility and improve rankings.
