Spending paternity leave trying to make the hobby better — built a free comp tool, looking for feedback!

Hoping to get some insight/make the hobby better with my paternity leave... Started building a bit with AI and wanted to build a free comp tool for the hobby that saved people some time

Do you ever pull comps mid-auction on Whatnot or while browsing eBay?

I've been building a tool that pulls recent sold comps from eBay, MySlabs, and SportsCardsPro directly in a Chrome side panel so you don't have to open new tabs. Works on Whatnot streams and general card browsing.

Would love to know:

1. Is checking comps mid-auction even realistic for you or too slow?

2. What do you currently use to check prices quickly?

3. What would make a comp tool actually useful during a live auction vs general browsing?

Not trying to promote anything — genuinely trying to understand if this solves a real problem before building further. Happy to share a link in the comments if anyone wants to try it and give feedback.
