Feedback on landing page design and content

I've built a web app called optiwing.com, It's a SEO keyword grouping tool that groups keywords into topical clusters that can be targeted with a single article or webpage. It enables SEOs and agencies to automate keyword research using live Google SERP data to create topical clusters and offers GPT-3 keyword suggestions. We support keyword exports from Ahrefs, SEMrush, and custom file uploads.

I'm a frontend dev but design isn't my primary focus, I'd love feedback on pretty much anything, design, device compatibility, copy/content.

Thanks!
