Eli P M May 10, 2026 v@ initial release

Interesting approach to SEO analysis. Good for quick checks on smaller sites.

Paul Apr 2, 2026 v@ initial release

Text/image/code/chat in one tool without a sharp wedge = buyers see you as replaceable → usually 30%+ drop in paid conversion vs specialized tools.

Why would someone pay you instead of using 2–3 better single-purpose tools?
