LinkedIn Comment Assistant – AI-Powered, Personalized Comment Suggestions
Make your LinkedIn engagement smarter, faster, and more impactful.
This Chrome extension uses ChatGPT to instantly generate short, human-like, and context-relevant comments for any LinkedIn post — directly inside your feed.

🚀 What It Does
The LinkedIn Comment Assistant adds a 💬 Generate Comment button to every post in your LinkedIn feed.
Click the button, and the extension:

Reads the post content (without storing or sharing it externally beyond your own API request).

Sends it to OpenAI’s ChatGPT API using your own API key for privacy and control.

Returns a natural, engaging, and emoji-enhanced comment tailored to:

The tone you prefer (e.g., professional, casual, witty, inspiring).

The maximum word limit you choose.

An optional key message you want to convey (e.g., agreement, appreciation, a counterpoint).

✨ Key Features
