The prompt engineering and result presentation was fun to build out, and I added some additional utilities to the results — quick links to searches on Amazon and an "Open All in New Tabs" button to make it easier to browse potential gifts. I also have some additional features in the works: explanations of why each gift would be good for the giftee, and the ability for the AI to ask additional questions to refine the recommendations (making it a more iterative / chat experience).
I have iOS and Android apps in progress (bless React Native) and hope to improve the make the search smarter down the road by e.g. incorporating product/review data using the new OpenAI embeddings API (maybe in combination with a search-focused database). I'm excited to see what HN gang thinks of my tool and if any last minute gifters like me find it to be a helpful resource for finding holiday gifts this year. Let me know what you think and if there are any other features you'd like to see!
