Hey HN, I was curious about how most companies and individuals were using AI without any meaningful insights. I built TokenSpend (https://tokenspend.dev/); we find existing ROI on AI code usage by tracking how much output was produced for your agent sessions, identifying inefficiencies with AI usage, and then, based on that data, we route you through the most efficient model. Solo devs can also use it as an AI Gateway with visibility into their spend.
