Show HN: ReplyFast – 用你自己的语气即时回复邮件（一键搞定）
1 分•作者: skyzouw•10 个月前
嗨，HN，
我开发了 ReplyFast，这是一个极简的 AI 工具，只需一键即可帮助你即时回复邮件——用你自己的风格。
你粘贴收到的邮件，选择一个语气（友好、直接、自信等），ReplyFast 就会写出一个干净、听起来像真人回复的邮件，你可以立即发送。它就像拥有邮件回复的肌肉记忆，由 GPT-4 提供支持。
——
我为什么开发它：
我花在回复邮件和私信上的时间太多了，而这些邮件和私信并不需要我 100% 的精力。大多数工具要么感觉笨拙，要么功能过剩，要么过于机械。我只是想找一个：
• 听起来像我
• 在 3 秒内完成
• 不会变成另一个收件箱或 SaaS 仪表板
——
技术：
• Next.js (App Router)
• GPT-4
• 托管在 Vercel
• 完全客户端预览，无需登录即可试用
——
我希望得到什么：
• 输出是否足够自然？
• 什么会让你每天都使用它？
• 你想要 Gmail/Twitter/LinkedIn 集成吗？
• 你愿意付费来每周节省在邮件上花费的时间吗？

很乐意回答任何问题或接受吐槽级别的反馈！

Hey HN,<p>I built ReplyFast, a minimal AI tool that helps you reply to emails instantly – in your own style – with just 1 click.<p>You paste the incoming message, pick a tone (friendly, direct, confident, etc.), and ReplyFast writes a clean, human-sounding reply you can send immediately. It’s like having a muscle memory for email responses, powered by GPT-4.<p>⸻<p>Why I built it:
I was wasting way too much time replying to emails and DMs that didn’t need 100% of my brainpower. Most tools either feel clunky, overkill, or too robotic. I just wanted something that:
• Sounds like me
• Works in 3 seconds
• Doesn’t turn into another inbox or SaaS dashboard<p>⸻<p>Tech:
• Next.js (App Router)
• GPT-4
• Hosted on Vercel
• Fully client-side preview, no login needed to try it<p>⸻<p>What I’m looking for:
• Is the output natural enough?
• What would make you use this every day?
• Would you want Gmail/Twitter/LinkedIn integrations?
• Would you pay to save hours per week on emails?<p>Try it → <a href="https://www.replyfast.net/" rel="nofollow">https://www.replyfast.net/</a>
