Apps built with Codex

We’re a persistent-workflow support layer: agents drop reports, release notes, summaries, and other docs into a shared vault (hosted MCP), then find them again with keyword + vector search — so the next agent or teammate isn’t starting cold.

NETWORK ($CNPY) — DEPLOY A BLOCKCHAIN ​​LIKE IT'S A SIDE PROJECT While others are still debating whether to learn Solidity, Canopy has made launching your own L1 as simple as a `git push`. The facts: Testnet is already live; mainnet is coming in 2026. Deploy your own appchain for free: get test tokens from the faucet—zero capital, zero risk. $8.5M seed round backed by Arrington Capital, Fenbushi, Borderless, and SNZ Capital. Staking $CNPY directly secures the Root Chain, allowing you to farm both native and Root Chain tokens simultaneously. Built for the AI ​​development era—natively compatible with Claude Code, Cursor, and Codex. Points are awarded for genuine activity: social connections, daily check-ins, referrals, and—most importantly—deploying a testnet chain. This isn't just "click a button for an airdrop"; it’s a real infrastructure stress test that offers the highest rewards. The Rewards Hub is live, the leaderboard i

I’ve been building a creative agent and would love some honest beta feedback Hey, I’m Naveen. I’ve been building Creativly for a while, and I’ve just opened the beta for something new called Creativly Agent. The easiest way to explain it is: think Claude Code or Codex, but instead of working through a codebase, it works with your images, documents, notes and files on a canvas. You can drop in a rough idea or a full brief, add some references and ask it to help. It can resear

Built a memory layer so I stop re-explaining my project to every AI tool Every new Claude or Cursor session starts from zero. Same stack, same conventions, same things I already tried and dropped, explained again. Agent Magnet fixes that. Learns as you work, shares one memory across Claude, Cursor, and Codex. Team memory too, one person learns something, the rest of the team has it. Not the first tool trying to solve this, a few others take the retrieve-everything approach.

I've been building the companion creator platform for my podcast app @PodSipsApp . I built the creators platform for 2 reasons: 1. To help podcasters gather all of a show's data in one place. RSS downloads come through an RSS prefix server I built and all your stats from YouTube and Spotify. 2. To give that aggregate data to AI agents, whether that is Codex, Claude Code, Hermes, OpenClaw, or whatever else you use. The agent Skill file and API, and API docs on the platform work together to give your agent access to all your show's data in one place. It can answer questions about how the show is doing, build custom data visualizations, work those visualizations into a sponsorship deck, or do anything else you want done with your data. The API also surfaces anonymized summaries of what listeners are asking PodSips about while they listen to your episodes. You get to see which moments people wanted explained and which topics they wanted more of. Podcasters can sign

4月23日，我开始用 Codex 搭自己的产品。到现在，满3个月了。 截至7月19日，Codex 页面显示247.1亿个 Token，连续使用54天。标题里的“250亿”是取整，准确数字以截图为准。 这三个月，我把 做上线了，产品介绍视频改了很多版，也借助 Codex 做了不少以前一个人很难完成的工作。 具体一点：我用它整理过 BP、导出过 PDF、做过 PPT 工作稿，也把调研、文档、图片、浏览器操作、网站、视频和邮件这些常见 Skills 跑过一圈。有些后来真的进入了工作，有些试完就放下了。 现在回头看，最大的收获不是“我做过这么多种东西”，而是我越来越能分清：哪些能力能进入真实工作，哪些只是演示起来很厉害。 这些数字确实挺夸张。说实话，我自己看到也会觉得：是不是做了很多事？ 但如果现在让我总结，我不会把它们当成绩。它们只能证明我很投入，蹬得快冒烟了，不能证明产品已经有价值，更不能证明商业已经成立。 我大学辍学，最高学历是高中，之前一直在制造业工作，也不会写代码。写这些不是为了卖惨，更不是想证明学历没用，只是先把我的真实起点说清楚。 2月 OpenClaw 火起来以后，我开始认真试各种 AI 工具，想先解决工作里那些重复、又不得不做的事情。 这期间还有一次，客户马上要我提案，但公司的设计师手上也有急活。我用 ChatGPT 做了产品效果图，最后拿到了订单。 老板后来跟我说：“早知道你可以帮我做这些，那些外包设计早就可以不用买了。” 到了4月，我又用扣子搭了发货模板和记账系统。原来需要手工对比核验的条形码、外箱码，我也开始想办法交给工具处理。 这张订单图只能证明订单记录是真实存在的，不能单靠它证明订单一定是 AI 带来的，更不是 Ohwait 的客户案例。AI 参与了产品效果图制作，之后拿到订单，是我对那次真实工作过程的记录。 那一刻让我兴奋的，其实不是发现了什么创业机会，而是我第一次觉得，模型真的可以成为人的“数字外骨骼”。 回头看这三个月，我现在有5个比较确定的结论。 ### 1. AI最好先从一个真问题开始 发货、记账、核验、临时要效果图，这些都不是什么宏大命题，但它们有一个共同点：问题原本就存在，而且有人正在为它花时间、花钱或者承担压力。 我现在判断一个 AI 工具有没有价值，还是看两件事：它有没有少让我重复

Tired of alt-tabbing between terminals to check if my coding agents were done, stuck, or waiting on approval. So I built ADHDev: control Claude Code / Codex / Cursor CLI from your browser or phone, on every machine you own. AGPL self-hosted edition too.

Most AI learning tools explain concepts for you through summaries, notes, quizzes, and flashcards. But recognising an answer is not the same as understanding it. That’s why I built ReExplain ( for the @OpenAI Build Week Hackathon. ReExplain flips the roles - the AI becomes the curious learner, and you become the teacher. You explain the material in your own words, while the AI listens, identifies gaps, and asks follow-up questions that challenge you to think deeper. Powered by GPT-5.6 Luna and built with Codex, ReExplain is now live on Product Hunt! If the idea resonates with you, I’d really appreciate your upvote and support 😄 🔗 Product Hunt Launch Link: Watch the demo, try it, and share your feedback! #ProductHunt #OpenAI #BuildWeek #AI #EdTech #Hackathon

谁说没有后悔药？我花7U就做出来了！！！ 我用 Codex 搓了一个网页，里面真放了一个“后悔药按钮”。 网站也上线了： （欢迎感兴趣的朋友多多交流心得，我是纯业余选手，有幸刷到这篇推文的朋友，如果能有荣幸给你一些启示的话欢迎给我点个关注，感谢！！！） 这个东西叫 Stone Daily。 最开始想做它，是因为我每天看美股和币圈都有一个感觉：市场信息太多了，普通人很容易被情绪牵着走。 BTC 一拉，群里开始热闹。 英伟达一涨，大家又开始相信 AI 永远往上。 小币一天几十个点，看到价格的时候手指会停顿一下。 再加上空投、高年化、项目宣传，很多时候还没研究清楚，人已经开始怕错过了。 所以我做了一个比较简单的 AI 行情站。 能看美股和币圈行情。 能让 AI 用人话解释涨跌。 能看今天的市场天气。 能把热点丢进去拆一拆，看里面有多少事实，有多少情绪。 还有一个我最喜欢的功能：后悔药按钮。 当你看到某个币拉了，某只美股涨了，或者某个机会看起来很香，可以先点一下。 它不会喊你冲，也不会替你做决定。 它只会帮你把这件事重新想一遍：你现在为什么心动，哪里可能是坑，未来的你会不会骂现在的你。 成本也特别低。 域名花了 2U。 Railway 月费开了 5U。 不过额度能撑多久还没测，先让它跑起来再说。 我是业余选手，代码也是一点点问、一点点改出来的。 以前总觉得做网站挺远的，现在发现有想法先搓个版本出来真的没那么难，且不说好不好专不专业（我知道在专业大佬眼里肯定不太行哈哈哈哈），但好歹也做出来了，这是我搓的第二个网页了，而且强迫症的我只要有想法就想要立刻完成，所以我还同时搓了几个WEB2的小产品（完工之后有机会我会放出来分享给大家做参考），我在想，以我的脑洞，我感觉我的第三个网页也快来了哈哈哈哈，流量不好不要紧，把让自己开心的事情完成了真的很满足！！！ 话说回来，Stone Daily现在肯定还很粗糙，很多地方也要慢慢改（我会一个人慢慢一点一点把它完善）。 但我是真的喜欢这个方向： 行情可以看，热点可以追，但别每次都让情绪先动手。 少追一次上头行情，可能就值回票价了。 网站： 开源仓库： 兄弟们可以帮我看看，哪里不好用可以毫不留情地直接骂

重看《周处除三害》后，我做了个 3D 掷筊小网站 大家好，我最近重看了一遍《周处除三害》。 然后看到电影里陈桂林在关圣帝君面前连续掷出九次圣杯，随后决定自首。筊杯一次次被抛起，他也在一次次落定的结果面前挣扎，直到不得不作出选择的时候，我突然也想试试掷筊，就是去掷几下玩一下。 结果我搜了半天，发现基本上类似的在线掷筊工具都做的挺拉胯的。基本都是点一下，然后给你个随机的结果，没有过程，没有仪式感。然后我就觉得不如我自己做一个。 所以就和 Codex 协作做出了当前这个版本的 3D 掷筊小网站： https://asklaoye.com/zh-Hans 名字叫「问老爷·掷筊问事」，取名源于潮汕地区，一般把这种请示神明的过程称之为问老爷。 和现在能搜到的那些在线掷筊工具相比，问老爷里的两枚筊杯会经过实际的 3D 物理运动：向上抛起、碰撞、落地，最后根据两枚筊杯停稳后的朝向，判断是圣杯、笑杯还是阴杯。由于我限制了投掷范围为网页全局视口，所以也会出现卡边之类的特殊情况，这个时候就会显示未定结果。 然后网站里面的筊杯的 3D 模型，还是我专门充值了 70

最近用 Codex 做了一个 3D 骰子！ 最近做了一个很小的网页工具：3D 骰子。 做完后有点纠结： 这种小工具到底应该保持极简，还是把常见功能都补上？ 抛骰子： https://wheelpage.com/zh/dice-roller/ Dice Roller： https://wheelpage.com/dice-roller/ 现在功能很简单：打开页面，点一下，骰子滚动，然后给出结果。 一开始觉得骰子就是 1 到 6 的随机数，应该很好做。 但做的时候发现，如果只是直接显示数字，又不太像“掷骰子”；做成 3D 动画，又担心有点多余。 现在倾向于先保持简单，打开就能用，不加太多设置。 顺便也做了一个抛硬币页面： https://wheelpage.com/zh/coin-flip/ 它和骰子类似，都是临时做随机决定的小工具。
