OpenAI today released a smartphone app for ChatGPT, the fastest-growing Artificial Intelligence (AI) application on the internet whose capabilities are both exciting and alarming.

The new application is initially available on iPhones in the US, and is expected to arrive “soon” in other countries and on mobile phones running on the Android system (Google), according to an announcement from the Californian company.

The mobile app, which is offered for free, allows, like the website, a conversation with the chatbot (interactive robot) with the user being able to ask him to write messages, explain technical concepts, suggest ideas, summarize notes, among many other possibilities.

The ChatGPT website, which went public in late November, surpassed one million users within a week, a record number. Two months later, the service already had about 100 million monthly active users, another record, according to a UBS study. This lightning use of ChatGPT is causing great concern worldwide.

Sam Altman, the president and CEO of OpenAI, speaking before a US congressional committee last Tuesday, advocated interventions by governments to regulate the development and use of Artificial Intelligence.
