I built an AI email writer because I was rewriting ChatGPT's drafts more than my own

Hey everyone,

I used to set a timer before opening my inbox. Fifteen minutes, max. Because if I let myself actually read everything — every client thread, every follow-up, every "just checking in" — I'd lose the entire morning and still feel like I hadn't said anything right.

I tried ChatGPT. Pasted in the thread, asked for a reply. What came back was technically correct and completely lifeless. "I hope this finds you well. Please don't hesitate to reach out." I spent more time deleting that fluff than it would've taken to just type the reply myself. At that point I was using AI as a very slow keyboard.

The problem wasn't the model. It was that generic AI has no idea how you write. It doesn't know you never say "per my last email." It doesn't know you open with a question. It doesn't know anything — because it read the last message, not the whole thread, and it definitely didn't read your sent folder.

So I built Replyf. It's a Gmail extension that reads a few of your sent emails to learn your tone, then drafts full replies — inside Gmail, with full thread context — that actually sound like you wrote them.

🔒 Privacy first: Your emails are processed on-the-fly. Nothing is stored on our servers.
🧵 Full thread context: It reads the entire chain before drafting, not just the last message.
⌨️ Zero tab switching: It lives right next to your Gmail reply button.

We just launched on Product Hunt today. If you've ever felt like your AI tool made you sound like a different person, I'd love your support:
