Mocca – A Mac email client powered by local AI

Hey HN! I recently built an app called Mocca( https://mocca.run ), an email client where all the AI runs locally on your Mac. No cloud and API keys. The model is bundled and runs offline. I made it as an experiment to see whether local AI has actually gotten good enough to power a real, everyday product and not just a cool demo. Too be honest its not quiet "there" yet but I still think it is genuinely useful for a very specific use cases. Would love it if you guys try it out and let me know what you think Thanks!
