As a developer working with AI APIs daily, I built AI Cost Bar to solve a real problem: the constant back-and-forth between documentation to calculate LLM costs for different models and providers. What makes AI Cost Bar unique: Instant calculations from your menu bar - no disruption to workflow Support for all major providers (OpenAI, Anthropic, DeepSeek, Azure) Always up-to-date pricing data via automatic syncing Custom pricing models for enterprise contracts Affordable one-time purchase ($2.99) For those who want to try before buying, check out our free web calculator. I'd love to hear your feedback and feature requests! P.S. If you're an AI developer, product manager, or consultant who estimates LLM costs regularly, I'd love to hear how you're currently solving this problem.
