Hey Product Hunt! 👋 My name is Briana and my partner and I built ToneDef SMS — just two people trying to make something useful. Here's what made us build it: We kept sending texts we immediately regretted. A message to a boss that came off way harsher than intended. An apology that sounded cold. A professional text that felt too stiff. Sound familiar? The problem is — in the heat of the moment, you can't always see how your own message reads to someone else. So we built ToneDef. Here's how it works: 📱 You text us the message you want to send 🎯 You tell us the tone you need (professional, friendly, apologetic, confident — whatever fits) ✅ We send back a rewritten version in seconds No app to download. No logging in. No copy-pasting between platforms. It works over SMS — right where you're already texting. What ToneDef can do: → Rewrite your message in any tone → Analyze a message you received ("is this passive-aggressive?") → Suggest how to respond to a tricky text → Summarize long text conversations → Read and analyze screenshots (Premium) We built this for anyone who has ever stared at a text wondering "does this sound too aggressive?" or "how do I say this without starting a fight?" That's honestly everyone. But especially people with ADHD, communication anxiety, small business owners texting clients, and people navigating tough relationship conversations. Basic plan is $6.99/month. Premium is $12.99/month. And we have promo codes for the PH community — drop a comment or DM me and I'll send you one to try it free. We're a tiny two-person team. Your feedback today means everything to us. Genuinely. 🙏 What's the most awkward text situation you've ever been in? Drop it in the comments — I'll show you what ToneDef would do with it.
