TweetAssist

TweetAssist is a browser extension that uses OpenAI's GPT models to help write tweets and replies directly inside Twitter, now X. Users choose a topic and a tone, and the extension proposes several draft posts or replies for them to review, edit and publish themselves. It suits individuals who post regularly and want help getting started on a tweet or responding to followers quickly. The extension offers tweet ideas on chosen topics, instant reply drafts, and a set of built in tones plus the option to add a custom tone that reflects the user's own style. It is available for both Chrome and Firefox. The product never posts anything automatically; every suggestion waits for the user to approve it. The vendor is explicit that the tool is meant for inspiration, and it asks users not to copy output verbatim, not to post spam or content that breaches X's terms, and to personalise drafts so they sound like a person. A free tier provides 10 tweet or reply requests on a one time basis, each returning three recommendations. The paid option is presented as a limited period lifetime deal that requires the user's own OpenAI API key, with a promotional code for 50 percent off; the lifetime price itself is not shown in the page text. Because the paid tier depends on a personal OpenAI API key, buyers should expect separate usage charges from OpenAI on top of the lifetime licence.
