Fine-tune any LLM in minutes, with one prompt

Hi Everyone! After months of building CallCow, we are very excited to finally launch on Product Hunt! 🚀 Back in October 2025, I built CallCow because I was not satisfied with what was in the market at the time - I needed a voice AI tool that can give me full control of the agent logic. So I built CallCow, a voice AI agent builder that aims to be both the easiest to use and the most customizable. The workflow is simple - 1. Create a voice agent workflow 2. Test the workflow within the browser 3. Connect with a phone number 4. Deploy We built our entire infrastructure in house, and we plan to keep it this way. With lots of voice AI tools already out in the market, our focus is specifically on serving small businesses. We already have a ton of usage from small businesses throughout US and Canada, and we are happy to showcase to what we have with the product hunt community. We are still in the early phases of building, so let use know if you have any feedback. Thank you for your support 💪.
