LinkedIn Copilot

About

LinkedIn Copilot is an AI-powered writing assistant that helps you write better LinkedIn comments, messages, and posts — directly inside LinkedIn.

A floating widget appears right where you type, just like Grammarly. Click it, choose your tone, and get perfectly crafted text in seconds.

HOW IT WORKS
1. Navigate to LinkedIn and start typing a comment, message, or post
2. A small floating button (✨) appears next to your text input
3. Click it to open the assistant panel
4. Add optional direction, pick a tone, and hit Generate
5. Insert the result directly into LinkedIn with one click
