I built an AI (inspired by Zach Wilson) that answers questions about stocks, websites & personal files with real math Inspired by one of the best AI Data Engineers, Zach Wilson, I built 3 apps in one: Stocks. Website. Your files. Ask questions in plain English and get answers backed by real Python math. That’s why the output is accurate , no hallucinations, because everything is grounded in your data. Every user gets a fully isolated database. Nothing is shared. You ca

I got tired of losing warranty claims because of faded receipts, so I built Warranty Tracker A few months ago, I had an expensive gadget fail just after I bought it. I knew it was still under warranty, but finding the receipt turned into a nightmare. The thermal paper had faded, I couldn't remember the exact purchase date, and I wasted more time searching than the repair was worth. That experience made me realize how scattered all of this information is. Receipts are in emails, PDFs, Wh

Built an AI Native Business OS where users don't spend credits, bring your own Claude/ChatGPT for infinite AI iterations, replacing 10+ tools for solo businesses. I'm a solo developer who just launched a platform to replace the 10+ tool stack that solo/small businesses like coaches, consultants, musicians. agencies and freelancers currently use (Kajabi, ManyChat, Mailchimp, Stripe, Calendly, etc.). The problem: Most AI app builders charge platform credits, which limits iteration. Solo ope

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。

I built a risk-first crypto analysis web app (plus a free profit calculator) after getting tired of hype-driven tools For the last few months I have been building CryptoYaan, a browser-based crypto analysis app, because most crypto tools either scream "to the moon" or quietly bury the risk. I wanted something that talks in plain language and always shows the downside first. What it does: Analyze any coin across Binance, Bybit, OKX and MEXC: trend, key levels, and a scored setup with en

I built a browser extension that pays you cash back for waiting on ChatGPT Every time you prompt ChatGPT, Claude, or Gemini, there's a few seconds of dead time while the model generates. I built Chatwait to monetize that gap and split the money with the user. How it works: when you hit send, one small sponsored card appears in the empty space below your message. You earn 50% of what the advertiser paid for that view. It doesn't read your chats. It is open source and you can
