Hi, I'm Kushagra, an AI/ML student building toward a SaaS product

Hi, I'm Kushagra, an MCA student studying AI and ML in Lucknow, India. I'm building AI projects with the goal of becoming a SaaS founder, and I'm still early in deciding which problem is worth committing to.

The most concrete work so far is ChatBook, which turns a WhatsApp chat export into a premium PDF keepsake. I've also built a Chrome extension with a FastAPI backend for tracking LLM token use and optimizing prompts, an AI food analyzer that estimates calories from photos, and computer vision prototypes using OpenCV and MediaPipe. I build mostly with Claude, Claude Code, Codex, and Copilot. The repos are small and have little public traction yet.

What I'd love from this community is feedback. If you've taken a small AI product from prototype to first paying users, which of these would you test first, and what would you check before doing so?
