What you built: I built an AI-powered newsletter pipeline that does research, writes content, generates images, applies my branding, and sends the final email via Gmail. I used Gemini for research (instead of Perplexity) because it’s free. One thing you learned: I learned how to troubleshoot fast and keep moving, especially through OAuth, SSL, and setup issues during a live build. One thing you’d improve: Next, I’d compare Gemini and Perplexity on the same topic to measure differences in source quality and final content.
