From running a store, the honest answer is that off-the-shelf AI tools cover most of it: product copy drafts, support replies and recommendations are all solved without custom work. Custom development only paid off for us where the AI had to touch our own catalogue and order data, which no plugin could reach. So I would start with the ready-made tools and only build custom when a specific workflow keeps breaking.
