HumanPost for X is a Chrome add-on designed to enhance the Twitter experience by providing AI-generated tweet replies and composition assistance. Users can easily generate replies by clicking the HumanPost button on any tweet or compose new tweets directly through the toolbar. The tool offers a selection of writing styles, including Casual, Pro, Funny, Contrarian, and Deep, ensuring that the generated text aligns with the user's intended tone.

With over 70 anti-AI patterns, HumanPost guarantees that the output does not resemble typical AI-generated text, making it feel more authentic. Each generated tweet is accompanied by three variants, complete with a viral score that estimates its engagement potential based on X's algorithm signals. This tool is particularly useful for non-native English speakers, offering a language mode to assist in crafting tweets that sound natural.
