Chrome Extension Developer | RozmeriGPT Smart LinkedIn Assistant

RozmeriGPT is an AI-powered Chrome extension we built at Entalogics that helps people write smart, personal comments and posts on LinkedIn in one click.

LinkedIn rewards people who show up and engage, but writing good comments and posts every day takes time and energy. RozmeriGPT reads the post you're looking at and suggests replies that sound natural and match your tone, right inside LinkedIn. We designed, built and launched the extension on the Chrome Web Store.

The goal was simple: help professionals, founders and freelancers engage on LinkedIn faster, without sounding like a bot. The extension had to:

Understand the actual post, not just spit out generic replies

Write in a voice that feels human and matches the user

Fit right into the LinkedIn interface with no extra steps

Stay fast, lightweight and respectful of user privacy

Follow Chrome's Manifest V3 rules and pass Web Store review

We built the extension to pick up the content of the post the user is viewing, so every suggestion is based on what was actually said. This keeps comments relevant and avoids the copy-paste feel of generic AI replies.

We wrote custom prompt logic on top of the OpenAI API to shape the output. Users can choose a tone, and the replies are tuned to LinkedIn's style: professional, friendly and to the point.

Instead of a separate app, the tools appear right where users already write. One click generates a suggestion, and users can edit it before posting, so they always stay in control.

The extension is built on Chrome Manifest V3 with a lean codebase, so it loads fast and doesn't slow LinkedIn down. We kept data handling minimal and focused only on what's needed to generate a reply.

We handled packaging, store listing and review, and shipped RozmeriGPT as a public extension on the Chrome Web Store.
