Show HN: ColdCopy – Generate personalized cold emails with AI
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!
