Honestly, this is underrated and underappreciated! Should have made product of the day, because I've literally been looking for something just like it! I can't track my own personal usage of all the AI tools I'm using, let alone that of the various teams I'm running for different projects. It gets to be a headache very quickly, and will only compound.
AI Spend looks like the perfect solution. Will update if I end up not liking it, but anything is better than nothing right now!
