AI LinkedIn Comment Generator – Free Chrome Extension (OpenAI, Gemini & Groq)

Description

Save hours on LinkedIn engagement — generate smart, human-sounding comments in one click.

AI LinkedIn Comment Generator (Lite) adds a one-click “AI Suggestion” button right inside LinkedIn’s comment box. It reads the post’s content and author, then writes a natural, context-aware reply instantly — using your own free API key from OpenAI, Groq, or Google Gemini.

🔥 Why you’ll love it

• One-click AI comments – no more staring at a blank comment box
• 3 AI providers supported – OpenAI (gpt-4o-mini), Groq (free tier, Llama 3.3/4), Google Gemini (free tier)
• Auto model discovery – always pulls the latest available models
• Rock-solid on LinkedIn UI changes – MutationObserver + fallback selectors keep it working
• Smart text insertion – 3-tier fallback so it always pastes correctly
• 100% private – API key stored locally in your browser, never sent anywhere except your chosen AI provider
• Built-in debug logs – easy troubleshooting if LinkedIn updates its layout
