Show HN: ReplyFast – AI replies to your emails instantly, in your own style

I built https://www.replyfast.net/ https://www.replyfast.net/, a lightweight AI tool that answers emails for you — in your tone, instantly, with one click. ⸻ Why? I was wasting too much time replying to emails — especially cold outreach, follow-ups, or scheduling replies. ChatGPT helped a bit, but I had to paste the email, prompt it properly, reword the result, and then clean it up. I wanted something that just worked — fast and clean — without connecting my inbox or over-engineering anything. ⸻ How it works: • Paste the email you received • Select the tone (friendly, neutral, formal…) • Click “ReplyFast” → get a ready-to-send reply in seconds • Copy/paste it into your email client No signup. No email integration. Just focused, fast replies. ⸻ Who it’s for: • Indie hackers, freelancers, startup founders • Anyone tired of typing the same replies over and over • People who want quick responses that actually sound like them ⸻ Would love feedback: • Is this something you’d actually use? • What would make it more trustworthy or useful? • Any features I should add or remove?
