AI Frontier Daily: Daily curated AI frontiers, straight to your inbox

Hey Product Hunt! 👋 I'm Oscar, a solo developer . I built AI Frontier Daily to solve my own problem. The problem: I follow AI development closely. Every morning I'd open arXiv, HuggingFace, Hacker News, Reddit, GitHub Trending… 15 minutes in, 20 tabs open, and I still hadn't found the 3 things that actually mattered. I was drowning in AI news but starving for signal. The solution: I wrote a script that pulls from 6 sources every morning, sends everything to DeepSeek, and asks it to be a ruthless editor — pick only 5–8 items worth my time. Then email them to me at 8 AM. I ran it for myself for 2 weeks. A few friends asked to be added. Then a few more. That's when I realized this could be a product. The tech: • TypeScript + Node.js • DeepSeek API for AI curation • GitHub Actions for daily scheduling • Vercel + Resend for email delivery • Gumroad for payments • Total server cost: effectively $0/month What makes this different: Most AI newsletters are written by humans (slow, limited sources) or auto-aggregated (noisy). This uses an LLM as an actual editor — it reads, compares, and selects. It's closer to having a junior researcher than an RSS feed. What's next: • Personalized topic filters (agents? vision? dev tools? you pick) • Web archive of past digests • "Ask the digest" — reply and get AI answers about past coverage On pricing: $7.99 one time. No subscription. I built this with near-zero running costs so I can offer lifetime access without going broke. If it saves you 30 minutes of scrolling, it pays for itself in the first week. Happy to answer any questions! And if you try it out, I'd love to know what sources or topics you'd like added. — Oscar
