I built and launched an AI toolkit for e-commerce sellers — would love feedback from IH

Hey Indie Hackers!
I wanted to share something I built and get honest feedback from this community.
The problem: Amazon, Etsy and Shopify sellers spend 10+ hours a week on repetitive writing tasks — product listings, review responses, ad copy, and customer emails.
What I built: SellerAI — a free AI toolkit that handles all of it in seconds.
5 tools included:

Listing Optimizer (Amazon, Etsy, Shopify)
Review Responder
Ad Copy Generator
Product Research & Market Analysis
Post Purchase Email Sequences

Current status:

Questions for IH:

Is $19/month the right price for e-commerce sellers?
What would make you pay for this immediately?
What am I missing in my marketing strategy?

Would love brutal honest feedback!
