Hey Product Hunt! I'm Ben, the solo founder of Penvox. I built this because every small business owner I talked to had the same problem — they know they should be posting on social media but they never know what to say. ChatGPT helps but everything sounds the same. Every plumber's post sounds like every other plumber's post. Penvox actually learns YOUR voice. You answer three prompts about your business, just talking naturally, and the AI breaks down how you communicate — your humor, your formality, your sentence patterns. Then every week it generates content that sounds like you wrote it, not like a robot wrote it. The AI gets smarter over time. When you rate your posts and tell it what performed well, it adjusts. By month 2, the content is noticeably more dialed in than month 1. Tech stack for the curious: Next.js, Supabase, Anthropic Claude, Stripe, Vercel. I'd love your honest feedback — what would make this more useful? What's missing? What feels off? I'm a solo founder and this is day 1, so your input directly shapes what gets built next.
