MaskedAIChat is a Windows frontend user interface to ChatGPT. It requires your own openAI API Key to work. The app allows to have text-based conversations with advanced language models like GPT (Generative Pre-trained Transformer) through API-interaction in real-time. While it has less features than the original chat apps from e.g. OpenAI it allows to control privacy like automatic masking of e-mail addresses.
Note: If you do not know what an API key is, this is not the right app for you. You can use this app only with your own openAI and/or Deepl API key. See the documentation of these services to get an API key.
