展示HN：ReplyFast – 以您的语气即时回复邮件（1键操作）
嘿，HN，
我开发了ReplyFast，这是一个简约的AI工具，可以帮助你以自己的风格在一键之内快速回复邮件。
你只需粘贴收到的消息，选择一个语气（友好、直接、自信等），ReplyFast就会生成一封干净、听起来像人的回复，你可以立即发送。这就像拥有一个针对邮件回复的肌肉记忆，由GPT-4驱动。
——
我为什么要开发它：
我发现自己在回复那些并不需要我100%思考的邮件和私信上浪费了太多时间。大多数工具要么笨重，要么过于复杂，要么听起来太机械。我只想要一个：
• 听起来像我
• 3秒内完成
• 不会变成另一个收件箱或SaaS仪表板
——
技术：
• Next.js（应用路由）
• GPT-4
• 托管在Vercel上
• 完全客户端预览，无需登录即可试用
——
我在寻找什么：
• 输出是否自然？
• 什么会让你每天使用这个工具？
• 你希望有Gmail/Twitter/LinkedIn的集成吗？
• 你愿意为每周节省数小时的邮件回复时间付费吗？

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>
