启动 HN：四月（YC S25）– 语音 AI 管理您的电子邮件和日历
嗨，HN，我们是来自April的Neha和Akash（<a href="https://tryapril.com">https://tryapril.com</a>）。我们正在开发一款AI执行助手，旨在帮助您在开车上班或任何您希望进行语音互动的时刻，轻松处理电子邮件和管理日程。
<p>这是一个演示：<a href="https://www.youtube.com/watch?v=ISKwEyuQQEo#t=50" rel="nofollow">https://www.youtube.com/watch?v=ISKwEyuQQEo#t=50</a></p>
在从旧金山到伯克利的40分钟通勤中，我的收件箱常常会涌入30多封邮件，而我还要安排连续的会议。我到达工作时已经落后，然后又得花一个小时来赶上进度。我们意识到，借助最近在语音AI方面的进展，我们可以解决这个“死时间”问题，并开始在移动中处理事务。
<p>您只需对April说话，“她”（抱歉，我忍不住拟人化）可以：</p>
- 总结重要邮件并标记需要关注的内容
- 发送我口述的回复（她会处理格式和语气）
- 审查我的日历并即时重新安排会议
- 从每个会议的邮件线程中提取上下文
- 将邮件归档/整理到文件夹中
<p>这是一个关于April执行更多任务的额外演示：<a href="https://www.youtube.com/watch?v=P8APprJ3-eY" rel="nofollow">https://www.youtube.com/watch?v=P8APprJ3-eY</a></p>
April使用Deepgram进行语音转文本（STT），使用Eleven Labs进行文本转语音（TTS），并基于LiveKit构建。我们为Google集成构建了自己的MCP（模型上下文协议）服务器，处理身份验证、速率限制，并在邮件线程中维护对话上下文。
<p>最有趣的部分是优化最低延迟，因为我们是一个调用频繁的工具应用。我们还在努力优化中断处理和轮流对话，使其感觉更加自然。</p>
April在App Store（iPhone/iPad）上可用。您可以在这里试用我们：<a href="https://apps.apple.com/us/app/april-ai-executive-assistant/id6747432952">https://apps.apple.com/us/app/april-ai-executive-assistant/id6747432952</a>。提供免费的3天试用，之后每月14.99美元。
<p>我们希望获得您的反馈：哪些电子邮件/日历工作流程对您来说最痛苦？除了Gmail和Google日历之外，哪些工具在语音接口下最有价值？</p>
我们会全天在这个讨论中回答任何问题，分享更多技术细节，并了解如何使April对您最有用。请随意评论！

Hi HN, we’re Neha and Akash from April (<a href="https://tryapril.com">https://tryapril.com</a>). We are building an AI executive assistant to help you get through emails and manage your schedule, hands-free while you drive to work, or whenever else you prefer voice interaction.<p>Here’s a demo: <a href="https://www.youtube.com/watch?v=ISKwEyuQQEo#t=50" rel="nofollow">https://www.youtube.com/watch?v=ISKwEyuQQEo#t=50</a><p>While driving 40 mins daily from SF to Berkeley, my inbox would flood to 30+ emails and I'd have back-to-back meetings lined up. I'd reach work already behind, then spend another hour just catching up. We figured with recent advances in voice AI, we could solve this dead time problem and start doing things on the go.<p>You can just speak to April and “she” (sorry, I can’t help anthropomorphizing) can:<p>- Summarize important emails and flag what needs attention
- Send replies that I dictate (it handles the formatting and tone)
- Review my calendar and reschedule meetings on the fly
- Pull context from email threads for each meeting
- Archive/organize emails into folders<p>Here's an additional demo of more tasks done with April: <a href="https://www.youtube.com/watch?v=P8APprJ3-eY" rel="nofollow">https://www.youtube.com/watch?v=P8APprJ3-eY</a><p>April is built using Deepgram for STT. Eleven Labs for TTS - built on top of LiveKit. We built our own MCP (Model Context Protocol) servers for Google integration, which handle auth, rate limiting, and maintain conversation context across email threads.<p>The most interesting part has been optimizing for lowest latency given we are a tool call heavy application. We are also trying to optimize the interruption handling and turn taking to make it feel more natural.<p>April is available on the AppStore (iPhone/iPad). You can try us out here <a href="https://apps.apple.com/us/app/april-ai-executive-assistant/id6747432952">https://apps.apple.com/us/app/april-ai-executive-assistant/i...</a>
Free 3-day trial, then $14.99/mo.<p>We'd love feedback on: Which email /calendar workflows are most painful for you? What tools beyond Gmail & Google calendar would be most valuable with a voice interface?<p>We’ll be in the thread all day to answer any questions, share more technical details and learn what would make April most useful to you. Comment away!
