Reply Boy

Reply Boy lives in your Chrome browser and writes replies for you. It is an AI reply generator that drafts responses and images for Twitter and LinkedIn posts, so you spend less time staring at a blank comment box.

You pick a mood for the reply, which changes the tone of what comes back, and the extension produces text and pictures quickly.

The developers say Reply Boy does not track user data, and the extension carries Google's Verified and Featured badges in the Chrome store.

Those are useful signals if you are wary of installing browser add-ons that read the pages you visit.

Replies come from AI models, so they can sound generic or repeat themselves if you accept every draft as is, and quality depends on the models behind them.

Reply Boy works best as a first draft that you edit so the reply still sounds like you.

For people who post and respond on social media daily, that trade is often reasonable.
