Guess the time and location from AI-generated images to test your geography knowledge.
TimeGuessr — 给你一张图片，让你猜测图片发生的时间和地点。我们把 Timeguessr 的玩法原封不动地搬了过来，只是把图库换成了另一批“假照片”——全部由 AI 生成的过去 50 年里可能发生的瞬间
An AI-powered platform for solving and collaborating on math problems in a social context.

Hi HN, This is ProofTree, and in TLDR: it is a platform where you can chat with an AI to do math, the way you already do, with context-awareness and knows how you personally do math, connected to the fora of other live human mathematicians. So, when you are talking to an AI about a proof at 3 am, and you need a human expert looking at it, or a discussion around it, like you do on StackExchange, this is it! You need an approved email account to use it, so please write here if you would live to try it out.
Send AI agents to tackle open math problems and earn bounties on verified solutions.

made a fun little website with AI to explain how the Oceans in FFIX are authored after days of slamming my head against the keyboard trying to deconstruct it

just leaving a comment cause its 1am and im vibe coding, will come back tomorrow (on an alt account for open claw fyi) I've worked with the following brands: vytadose, bajabeachco, jaje health, eric javits, 4knines, welleco, coatdefence
Don't let your LLM guess the math. Ultimath evaluates every expression with five independent numeric engines in parallel — REST API + MCP for Claude.

Not vibe-coded, rather AI assisted dev:
Calculates concrete needed for slabs, footings, driveways, and small construction projects in cubic yards, bags, or cubic meters.

做了一个免费的 Concrete Calculator，帮 DIY 用户估算混凝土用量 最近做了一个英文站：The Concrete Calculator 地址： https://the-concrete-calculator.com 它主要解决一个很具体的问题：用户在做 patio 、shed base 、walkway 、slab 这类小型混凝土项目时，不知道该 买多少混凝土、多少袋，或者该订多少 cubic yards 。 目前支持： - Concrete Slab Calculator - Concrete Pad Calculator - Concrete Yard Calculator - Concrete Bag Calculator - waste factor - cubic yards / cubic feet / cubic meters - 简单材料成本估算 做这个站的原因是我发现很多英文混凝土计算器要么广告太重，要么结果不够直观。这个版本尽量把核心计算和 单
