Au Coup de Pouce Numérique: Cold email automation for freelancers — no cloud, pay once

Hey Product Hunt! 👋 I built ProspectAI because I was tired of paying €50-100/month for email prospecting tools as a small business owner. The problem: every serious cold email tool is SaaS. You pay every month, your data lives on their servers, and the moment you stop paying — everything's gone. So I built the opposite: a Windows app that runs entirely on your machine. Your prospect list, your emails, your campaign results — all stored locally. No account, no cloud, no subscription. The AI part (Claude Sonnet) helps you write personalized emails in seconds. You describe your offer once, pick a tone, and it generates your initial email + 2 follow-ups. Then ProspectAI sends them automatically at the intervals you choose. It's been working well for my own business, and I figured other freelancers and small business owners might want the same thing. Happy to answer any questions — especially if you're curious about the "local-first" approach in a world where everything's moving to the cloud. 🙂
