ChatGPT is an AI-based text platform based on the state-of-the-art GPT-4 architecture. Trained with billions of parameters, ChatGPT creates impressively detailed and high-quality texts that were hardly possible before. Especially for complex tasks, you get precise answers quickly and easily.
The principle is very simple: you give ChatGPT a clear instruction – a so-called prompt – and receive a finished, convincing text back within seconds. Whether you need creative content such as blog articles, product descriptions or social media posts – ChatGPT provides you with fresh ideas and exciting texts.
ChatGPT also provides effective support in the marketing sector, helping you to develop new campaign ideas or creative slogans. In customer service, the AI helps you to automatically generate answers, significantly reducing the response time to customer inquiries.
Integrating ChatGPT into existing systems is very easy: you can easily integrate it into CRM systems or chatbots via the API and save valuable time. Thanks to established plug-ins for content management systems such as WordPress, integration takes just a few clicks.
ChatGPT also offers the option of creating images and graphics directly via the chat. Depending on the version, you will receive two different reactions from which you can choose your favorite. This is how we created the post image for this article, for example.
Here you can find detailed instructions on how to create images with ChatGPT
