Feedback Request - Online Tools / Calculators

Made a thing this weekend and had some fun.... redacted

Which prompted a broader question... while I'm not expecting to replace bespoke Excel models for the heavy lifting, are there any "small and repeatable" analytics needs in the search fund community that could make your lives easier?

Ideally replacingredactedminutes of Excel work / online research and something that you would do on a regular basis?

Bank models are definitely out of scope, given the tremendous variation in deal structure & business details - too many flavors to address in a free model.. But got anything else that would be useful?
