TechTalk is a GPT that simplifies the comparison of tech products for users. It bypasses the complex technical specifications often presented by manufacturers and presents the comparison in a language that is easy to understand, hence 'Tech in plain English'. Designed by Anson Lai, TechTalk requires access to ChatGPT Plus, indicating it is a premium service. Users start a conversation with the GPT by specifying the two tech products they would like to compare. The GPT then provides them with a straightforward comparison of the two items. TechTalk covers a wide range of tech devices, from graphics cards to laptops, tablets, and headphones, making it a versatile tool for users with varying levels of tech knowledge. It does not only compare products based on technical features, but also considers the use-cases and functionalities relevant to the user, making the tool practical, easy to use, and user-focused.
