RankForge — keyword research tool for KDP authors (beta testers wanted)

Hi everyone,

I built RankForge (https://rankforged.com) — a tool that helps Amazon KDP authors find profitable keywords and categories.

Features:

• Keyword validation (search volume vs competition)
• Category profitability analysis
• Competitor tracking

Looking for beta testers who publish on KDP. Free tier available, no credit card needed.

Specifically want feedback on:

• Are the keyword suggestions useful?
• Is the UI intuitive?
• What features are missing?

Thanks!
