Show HN: ColdCopy – Generate personalized cold emails with AI

2 ZeeeTH 1 7/9/2025, 1:57:31 AM coldcopy.xyz ↗

I built ColdCopy because I was spending way too much time writing cold emails that still sounded generic.

The tool generates personalized outreach messages using AI. You fill out a form with your details + recipient info, pick your tone (professional/friendly/direct), and get a tailored email in 30 seconds.

Built with Next.js 14, TypeScript, and OpenAI API. Took about 3 days from idea to launch.

The hardest part was prompt engineering - getting the AI to generate emails that sound human rather than corporate template garbage. I created different prompts for each message type and tone combination.

Currently free to try (3 generations per day) while I gather feedback.

Happy to answer any questions about the build process or get feedback on the approach!
