About ZonGuru
ZonGuru is an Amazon seller toolkit built around what it does best: AI-powered listing optimization. Its flagship Listing Optimizer 4.0, powered by GPT-4, goes beyond generic AI text generation by integrating directly with ZonGuru's proprietary keyword research tool, Keywords on Fire, to create listings that are both compelling to shoppers and optimized for Amazon's search algorithm. Sellers can customize AI output with power prompts that control tone, brand personality, format, and product-specific details. The platform includes product research, niche analysis, keyword tracking, and sales analytics, but its core strength is the listing creation workflow. ZonGuru's Listing Strength score compares your listing against up to 8 competing ASINs in real-time, showing exactly where you're winning and losing on keyword coverage, content quality, and listing completeness. With plans starting at $29/month (annual), ZonGuru offers one of the most affordable entry points for AI-powered listing optimization among dedicated Amazon seller tools.
