Why I built ColdSeq I was sending cold emails for my freelance work, but everything I wrote sounded robotic. ChatGPT was too corporate. Claude had rate limits and constant "try again later" messages. So I built ColdSeq. It uses the same quality AI as Claude, but without the limits. You describe your product, target customer, and pain point. 60 seconds later you get 5 human-sounding emails with subject lines, timing recommendations, and the psychology behind each email. What makes it different: - Actually sounds like a human wrote it - No "try again later" limits - Free tier (3 sequences/month, no credit card) - Starter ($19/mo) and Pro ($39/mo) for unlimited Tech stack: Next.js, Supabase, Gemini AI, PayPal I'd love your feedback.
