Reply Boy

Reply Boy is an AI service and Chrome extension that helps you write quick replies and posts for X (Twitter) and LinkedIn.

How Reply Boy works

It analyzes posts in your feed and generates ready-to-use replies and new posts in seconds. You can choose a tone and format depending on the conversation and your goals.

• Tones: romantic, funny, ironic, philosophical, provocative, or “hater”
• Formats: questions and affirmations to spark discussion and increase engagement

Who it’s for

Reply Boy is useful for people who need to stay visible on social media but don’t always have ideas on hand.

• Content creators
• Marketers
• Founders
• Anyone building a personal brand on X or LinkedIn

Privacy and setup

The extension doesn’t require registration, doesn’t track user data, and can be installed directly from the Chrome Web Store. It’s a practical way to keep your feed activity consistent without spending a lot of time drafting every reply.
