AI-powered replies, tweet ideas and rewrites for X (Twitter) right from your browser
Reads the tweet you are responding to and drafts a human-like reply in seconds, so you can engage with your timeline far faster than typing each response from scratch.
Type a subject and Tweeteasy produces ready-to-edit tweet drafts, which keeps your posting cadence going even on days when you have nothing in mind.
Highlight any part of a draft and ask the AI to add emojis, shift the tone, tighten the wording or expand the point, instead of regenerating the entire post.
Non-native English speakers can translate tweet content into English and have spelling and grammar errors corrected before publishing.
