Is it available now?
Yes. The free extension is on the Chrome Web Store and also works in Edge. Pro is next; join the waitlist to hear first.
Does it break Amazon's rules?
No automation, no scraping of Seller Central. It only reads the page you're looking at.
Why so cheap?
Small, focused tool, small team, no investors to satisfy. We'd rather keep sellers for years.
