About Seller Stacked

Honest AI tool reviews, free calculators, and in-depth guides -- built by a real e-commerce operator with over eleven years of experience across Amazon FBA, Shopify, and eBay.

Seller Stacked is built and run by Mark Dunne, founder of Supplements Wise - a UK-based premium supplement brand selling across Amazon FBA, Shopify, and eBay.

I've been running e-commerce operations for over eleven years. I handle everything from Amazon PPC and Google Ads to Shopify theme development, SEO, product sourcing, and compliance. I'm not a journalist covering AI tools from the outside - I'm a seller using them daily to run a real business.

Why I built this

Most “best AI tools” articles are written by content farms that have never sold a product online. They regurgitate feature lists from marketing pages and rank tools by whoever pays the highest affiliate commission.

I built Seller Stacked because I was tired of wading through that noise myself. Every tool on this site has been evaluated through the lens of actually running a store - with real revenue, real customers, and real time constraints.

What you'll find here

40+ AI tool reviews

Every tool in the tool directory is independently scored on ease of use, value for money, and platform integration. Reviews include pricing breakdowns, features tested, pros and cons, and guidance on who should (and shouldn't) use each tool. Browse by platform or category to find tools that match your store.

In-depth guides and comparisons

The blog covers platform-specific tool roundups, head-to-head comparisons, and practical workflows. Some of the most popular guides include:

What makes this different

  • Operator perspective. Every review is written from the perspective of someone who actually runs an online store. I evaluate tools based on how they fit into real e-commerce workflows, not just their feature lists.
  • Interactive tools, not just articles. The AI Stack Quiz, PMax Calculator, and Listing Scorer give you personalised answers - not generic listicles.
  • Honest scores.I tell you when a tool isn't worth it, even if we'd earn commission from recommending it. Plenty of free tools outperform paid ones, and I'll say so.
  • E-commerce specific.Generic AI tool reviews don't help sellers. Every score on this site reflects real utility for running an online store.

How we review tools

Each tool is tested against real e-commerce workflows. I look at time saved per week, revenue impact, learning curve, and pricing at scale. Reviews are structured with features tested, detailed pros and cons, seller profiles for who should and shouldn't use the tool, and head-to-head comparisons against alternatives. You can see the full methodology in action in guides like AI Product Photography Tools: I Tested 8 Options Side by Side.

How we make money

Some links on this site are affiliate links. If you sign up for a tool through our link, we may earn a commission at no extra cost to you. This never influences our scores or recommendations. We recommend plenty of free tools and regularly advise against paid ones.

Our editorial process is simple: I test the tool, form an opinion, write the review, then check whether an affiliate programme exists. The review is never written around the commission.
