This article is part of TechRadar's AI Week 2025. Covering the basics of artificial intelligence, we'll show you how to get the most from the likes of ChatGPT, Gemini, or Claude, alongside in-depth features, news, and the main talking points in the world of AI.
While you can use ChatGPT (and Google Gemini) in a web browser, or on your mobile device, without even logging in, there are different subscription options available, and if you are going to use it regularly then you might soon hit up against the limits of a free account.
