In 2023, artificial intelligence (AI) has grown tremendously with a commendable surge in the popularity of ChatbotGPT apps in smartphones. These apps are built around the GPT-3.5 language model, otherwise known as the Generative Pre-trained Transformer model, creating remarkable conversational interactions for users. While OpenAI's own ChatGPT, under the leadership of Sam Altman, serves to assist in language-based tasks, it does not have a mobile app. This gap in the market saw the rise of various competitive AI chat apps in 2023 that offer some exceptional alternatives to ChatGPT given several limitations associated with it - such as its inability to provide genuine information, generate AI images, or execute voice commands, among other things.

Amongst these alternatives, now we look at the top 10 most popular ChatGPT Apps for smartphones in 2023 that stand out for their interactive and captivating conversational experience. The very first one worth mentioning is ChatSonic, a platform that aims to streamline communication and increase productivity. Integrating effortlessly with Google Search, this chat platform is based on artificial intelligence from Writesonic and is, therefore, proficient in both text and image generation.
