Falvox 👇 It turns YouTube transcripts into personalized AI courses instead of giving users only another summary. Would love your honest rating.

I vibe-coded an anti-vibe-coding app. Yes. I used AI to build a whole academy that trains you to stop blindly shipping AI code. Five levels. Security quizzes. Badges. A streak. The whole “read the error before you panic” curriculum. It’s like building a gym while eating pizza on the treadmill. Play it here → https://videcodingacademy.web.app This post was also vibe-coded. Happy Vibe Coding 😂 submitted by /u/rontop151 to r/SideProject [link] [comments]

Practice whistling with real-time pitch feedback and progressive exercises from single tones to full melodies.

HowToWhistle:像唱 KTV 一样练习吹口哨 一直想提高吹口哨技巧,搜了一圈发现网上的教程都是文字和视频,练的时候根本不知道自己吹得对不对。 想到可以像 KTV 一样,有个音轨对比,于是干脆自己搓了一个练习网站:[https://howtowhistle.org/]( https://howtowhistle.org/) 核心思路是用浏览器的麦克风做实时音高检测,你对着麦克风吹,页面会显示你当前的音高和目标音的偏差,类似 KTV 唱歌时的实时评分。功能大概有: - 实时音高反馈,能看到自己吹的是哪个音、偏高还是偏低 - 从单音长音开始的渐进式练习,到音阶、再到简单旋律 - 纯前端实现,声音不上传,无需注册 目前还比较简陋,欢迎大家试玩和提建议。

I don’t know why isn’t it getting that much attention it’s actually a big deal for people who do vibe coding, for people like who develop micro apps daily. As a teacher it’s so ise to just tell students to go to and practice tables… It’s so amazing

Learn languages by watching real video clips from movies and podcasts with native speakers.
u/Ecstatic-Rooster3295 · Reddit
Built a small tool to see how native speakers actually use words across different media (movies, podcasts, etc.) I used to use YouGlish a lot while studying, but it always felt pretty basic—you watch a clip, and that's it. I wanted a way to filter clips by specific media (movies, TV shows, podcasts), get translations, and actually ask an AI why someone used a word in that specific context when textbook definitions fell short. So I spent some time building my own version to

AI-powered English learning game where kids photograph their schedule to generate vocabulary lessons through animal villagers.

My kid goes to an English-only school in the US, but we speak Chinese at home. So I built her a tiny Animal Crossing-style island to learn English 🏝️ Snap a pic of the teacher's daily schedule → AI turns it into a lesson pack → she learns words from animal villagers, shakes apple trees, goes fishing 🎣 100% hand-written Three.js, zero assets, no backend. Try it:
