LinkedIn AI Comment Assistant is a small browser extension aimed at people who want to stay active in LinkedIn conversations without staring at an empty comment box. It was published on the Chrome Web Store by independent developer Manuel Fuss (manuel-fuss.de) and is distributed under the MIT license. The concept is deliberately narrow: rather than being a full social media suite, it adds a single "Generate AI Comment" button inside LinkedIn's comment area.
When you click it, the extension collects the context of the post you are viewing along with the comments already present, sends that text to the OpenAI API using an API key you paste into the extension popup, and displays a suggested comment. You can edit the suggestion before posting, so the final wording stays under your control. Because you bring your own key, usage is billed by OpenAI directly rather than by the extension author.
Setup is three steps: install from the Chrome Web Store, open the extension popup and save your OpenAI API key, then reload any open LinkedIn tab. The developer explicitly frames the extension as a testing and experimentation tool and warns against flooding LinkedIn with AI-generated content, so it is best treated as a drafting accelerator rather than a fully automated posting bot.
