Comment Assistant In LinkedIn™

Comment Assistant In LinkedIn™ targets LinkedIn users who want to stay active in the feed without spending a long time writing each reply. Rather than redirecting you to another tab, it injects a ChatGPT-style interface directly into the LinkedIn website so the reading, drafting and posting steps stay in one place.

The extension triggers on selected text. You highlight a post or discussion, press Ctrl/⌘+M, and choose what you want done — the description suggests mixing requests such as "create a reply, comment, make it words limit, or add some fun" by separating them with commas. The switch control then produces a response you can edit in place.

The publisher explicitly notes that this is an independent project with no relationship to LinkedIn or LinkedIn Inc., so it is a third-party utility rather than an endorsed feature. It relies on your own OpenAI API key, which you set once in the extension before the assistant can generate anything. With a 4.1 rating across a modest reviewer base, it is a lightweight option for people who already have an OpenAI key and want their commenting kept inside the browser.
