做了一个免费的声音表达分析工具,录 5–15 秒就能看到反馈 最近做了一个小工具:Voice Impression Checker 。 它想解决的问题很简单:我们经常知道自己“说了什么”,却不太清楚这段话听起来是什么感觉。 打开网站后,只需要录制 5–15 秒自然说话的声音,工具会从这一次录音中分析: - 清晰度、语速、稳定性、能量和声音变化 - 听感上的温暖、自信、亲和力和参与感 - 这次表达做得比较好的地方 - 下一次录音可以尝试改进的一件事 网站还提供了 Rate My Voice 模式,可以针对面试回答、演讲开场、自我介绍和日常交流等场景进行练习。 需要特别说明的是,它不是声音好坏评判,也不会通过声音判断性格或身份。所有结果只描述当前这一次录音的表达效果,更适合用来反复练习和比较不同说法。 目前网站免费使用,不需要注册账号,录音仅用于生成当前报告,不会保存。 网站地址: https://voiceimpressionchecker.com/ 这是一个刚完成的早期版本。如果你愿意体验,欢迎告诉我结果是否容易理解,以及你最希望

I pivoted from my initial idea after realizing I was solving the right problem at the wrong time When I started building GaaS Guard, it was an AI governance tool for companies. The idea was to help organizations defend against prompt injection and unsafe AI interactions. It was technically interesting, and I still genuinely believe I was solving a real problem. The problem was, it just wasn’t selling—to be brutally honest. Here’s how I actually ended up pivoting. I started using a b

Fidibeki — Product feedback that finishes the job Building products is what drives me. While working on my own products, I noticed the same problem: feedback comes in, loses context, and users rarely hear what happened next. So I built Fidibeki. Users can report issues directly inside a product with screenshots, audio, or session replay. I can triage everything in one inbox, merge duplicates, track progress, and keep reporters updated. Privacy is built in: session replay
