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.
