BanterBird reads the post you're on and drafts a reply in your voice — you stay in the driver's seat the whole time.
It reads the post — text and images — so suggestions actually respond to what was said, not generic filler.
Witty, supportive, contrarian, or a question — pick the angle and regenerate until it sounds right.
Every reply is a suggestion. You review, edit, and post it yourself — nothing is ever sent automatically.
Bring your own key. You pay OpenAI directly for what you use — no subscription, no markup.
No analytics, no tracking. Your key and settings stay in your browser; posts go straight to OpenAI.
A floating navigator and keyboard shortcuts let you sweep a timeline and draft replies without leaving the page.

Yes. The extension runs no analytics and stores your key and settings locally. When you generate a reply, the post text is sent directly from your browser to OpenAI using your key — never through our servers.
BanterBird works on x.com and twitter.com. It only runs on those sites and acts only when you trigger it.
