Overview
LinkedIn AI Comment Assistant is a Manifest V3 Chrome extension with a product landing page. An AI Comment button sits under each LinkedIn feed post; users pick a tone, get three suggestions, insert with one click, and always review before posting.
Problem
Writing thoughtful LinkedIn comments at volume is slow. Generic AI tools sit outside the feed and do not match the post in view or the user's preferred tone.
Solution
Built a content-script extension on linkedin.com plus a marketing site with install CTAs. The extension extracts post text, returns three tone-aware suggestions, supports a post writer, and never auto-posts.
My role
Sole engineer — Manifest V3 architecture, content scripts, popup UI, backend integration, store listing, and product landing page.
Key features
- Inline AI Comment button on every LinkedIn feed post
- Three context-aware suggestions and four tone styles
- One-click insert — never auto-posts
- Post writer for full drafts from a topic
- Marketing site with Chrome Web Store install flow
