Hey Product Hunt! I'm Curtis, and I built ForthWrite because every AI email tool I tried made my replies sound like they were written by someone else.

The problem: generic AI drafting is a commodity now. Gmail ships it for free. The harder problem is sounding like you. "I hope this email finds you well" under your name costs trust, slowly.

The bet: a writing tool that gets measurably more like you every week. Not a one-shot prompt. A system that compares every AI draft to what you actually sent, learns from the gap, and shows the improvement curve in the dashboard.

How it works:
• Add the Chrome extension for Gmail, Outlook, and LinkedIn, or draft from the web app with nothing to install
• Write normally. ForthWrite learns from what you change, not just what you accept
• Hit "Generate Draft" in any thread for a draft in your voice
• Pro adds auto-draft, batch, Prompt Lab

What makes us different:
• Closed-loop learning from real edits, with a visible voice-match curve
• Free tier is real: 10 drafts/week with voice matching, no API key, no card
• Honest privacy: voice data encrypted, isolated to your account, you can delete anytime
• 14-day Pro trial if you want auto-draft, batch, and Prompt Lab
• 9-provider BYOK on paid plans (bring your own key, encrypted at rest)
