I appreciate it would be a big strain on your system, but I;d love to be able to know who I have exported and just look them up again, without credit use.
For instance, I can filter a technology from my exported CSV, but I’d liek to be abel to put my shortlist back in to your system, to check for updates and other info.
I guess it’s impractical though?

Not impractical at all. There is an export history, and when you download it again, it automatically updates the info + doesn’t cost you any credits.
Right now, we’re working on upload a list of websites -> get it scanned.
So you’ll be able to even take a portion of the same list of websites, and get it scanned on demand.
