Show HN: I built an AI tool that writes replies to your emails automatically
1 comments
Hey HN,
I built ReplyFast, a small AI-powered tool that writes email replies for you.
You just paste the incoming email, and it generates a reply using GPT-4 — straight to the point. You can edit it or copy/send as is. No login required, no setup, no integrations. I just wanted something fast and lightweight to avoid replying to the same messages over and over (demo requests, basic support, cold emails, etc.).
It’s not a full CRM or a productivity suite — just a focused tool for fast replies.

Built it solo in a few weeks. I’d love feedback on: – Is the idea useful to you? – What would make this 10x better? – Would you pay for it?
Appreciate any comments or suggestions

I built a small AI tool that helps you reply to emails faster. It reads the incoming message and generates a relevant response using GPT-4. You can tweak it, copy it, or just send it right away.
I got tired of answering the same kinds of emails manually (demo requests, support, etc.), so I built this to speed things up. No integrations, no setup — just paste your email and get a suggested reply.
