Hi ProductHunt, I'm one of the founders and developers of CollectHolo.com! 👋 Being from Europe, we were quite frustrated before we started building CollectHolo as it's really hard to keep track of a multi-lingual Pokemon card collection. The hard part is that every language, every condition and every variant has its own price. And then there's several marketplaces. A card in English can have a different price on the US market than on the European market. A German card isn't worth the same as an English card. Our goal was to change and simplify that and give users the best possible insights into the market, including support for graded cards. We've put a lot of passion and love into our project and we've already released an iOS and Android app and hope that users enjoy our project as much as we do. Thank you so much for reading all of this and for checking us out!

I've always been a Codex and ChatGPT user but especially Astra changed quite a few things. Especially when it comes to research, computer use and huge data research. Computer use worked well on Sol as well but honestly, Astra is much smoother. It already helped me to set up things where no MCPs and plugins existed like the Google Tag Manager, web and app tracking with pixels from TikTok, Reddit, ... and much more.
