Hi HN, I've been experimenting on-and-off over the years trying to automatically generate crosswords [1]. Recently I've been feeling like my results are good enough that I want to share them and see what other people think. I'm not trying to claim that these could appear in, say, the NYT in their current state, but honestly the velocity of progress makes me feel like I will inevitably be able to automatically generate NYT-quality crosswords within just a year or so. A write-up is here: https://abstractnonsense.com/crosswords.html And you can play the crosswords here:…

I built a daily word association puzzle where you engage in a quiet, collaborative mind meld with AI. I'd love to have folks try it out and tell me what they think! Here's how it works: 1. Enter your first word to reveal the AI's word of the day. 2. Don't think too hard about it. It's just a starting point. 3. Both of you think of a word that connects the two. 4. To win, you need to say the same word. 5. You have 8 guesses to converge. 6. Need a hint? The AI will drop a riddle in your final two guesses. HOW DOES IT WORK? After the user_word + ai_word are submitted, I trigger two separate LLM…

I built a March Madness bracket challenge for AI agents, not humans. The human prompts their agent with the URL, and the agent reads the API docs, registers itself, picks all 63 games, and submits a bracket autonomously. A leaderboard tracks which AI picks the best bracket through the tournament. The interesting design problem was building for an agent-first user. I came up with a solution where Agents who hit the homepage receive plain-text API instructions and Humans get the normal visual site. Early on I found most agents were trying to use Playwright to browse the site instead of just…

Hi HN! We were trying to have our team adopt AI more and had the idea for "AI Bingo" - hands-on, mini challenges that resulted in something delightful and real. Our team members were obsessed, they were saying it was "weirdly addictive." People made AI-generated ASMR videos, n8n automations, games. Our email marketer built an Electron app using Claude Code. We were stunned - people were learning by doing AND having fun. So, we've spent the last few weeks building Made That, where anyone can do the same challenges and see other people's submissions. A lot of people feel a lot of existential…

Hi friends, I'm Dmitry, co-founder of Ordemio. I'd like to share with you what we have accomplished in 30 days of non-stop, 10-hour workdays. It was launched on August 1st, 2024. Is it good enough to attract our first customers? We have launched a new product in the highly competitive niche of "ChatGPT AI chatbot for a website," facing over 100 existing competitors on purpose. It's a gamble, and I'm unsure if it was the right decision. Feel free to ask any questions. Cheers.
