做了一个海外 TikTok 直播打赏收益的计算器 大家好,最近关注到海外 TikTok 直播打赏很火,很多主播正在靠直播礼物默默赚钱。不过观众花了多少钱、平台抽走多少、主播实际能拿到多少,计算起来并不直观。 所以我做了一个 TikTok Coin 收益计算工具。 地址: https://coinvaluecalc.com/ 这是什么? TikTok 观众先购买 Coins ,再用 Coins 给主播赠送礼物;主播收到礼物后,会获得对应的 Diamonds , 再用 Diamonds 转化为收益。 工具输入 Coins 数量,工具就能估算观众的购买成本、TikTok 平台费用,以及主播最终可以获得的收入。 特点: ✅ Coins 、Diamonds 和美元快速换算 ✅ 区分观众花费与主播收益 ✅ 收录常见 TikTok 直播礼物 ✅ 完全免费,无需注册,即开即用 不同地区和充值渠道的价格可能不同,计算结果仅供参考。欢迎大家体验和提建议。

Got curious what a pointless meeting actually costs me, ended up building wage calculator www.wagescalc.com I was sitting in a meeting that should have been an email and wondered what that hour was literally costing me in wages. Turns out about $29. Then I wanted to know the per-minute number. Then per second. So it's a salary-to-hourly converter. There's a meter at the top that starts counting the second the page loads and shows what you've earned since you opened it. Leave the tab op

Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast.
