Hey HN! Ever wondered if there’s a fragrance out there that smells just like your favorite but from a completely different brand? That’s what got me thinking, and after a weekend of deep work, I created DupeFinderAI. What It Does: DupeFinderAI is an AI-powered tool that scans and compares thousands of perfumes, identifying those that share nearly identical notes and aromas. Whether you're curious about scent similarities or just love discovering new perfumes, this tool has you covered. How I Built It: - Scraped data from 40,000+ perfumes over a weekend - Used that data to train the AI on…

We have a dataset of 3,095 standardized AI responses across 43 prompts. From each response, we extract a 32-dimension stylometric fingerprint (lexical richness, sentence structure, punctuation habits, formatting patterns, discourse markers). Some findings: - 9 clone clusters (>90% cosine similarity on z-normalized feature vectors) - Mistral Large 2 and Large 3 2512 score 84.8% on a composite metric combining 5 independent signals - Gemini 2.5 Flash Lite writes 78% like Claude 3 Opus. Costs 185x less - Meta has the strongest provider "house style" (37.5x distinctiveness ratio) - "Satirical…

I built Meepo – a smarter search engine for a local (South African) fashion and homeware store. I have no affiliation with said store. I built this for myself, because I was frustrated at how difficult it was to find what I wanted with the existing search engine + I was curious how well CLIP (a relatively new AI technique with open source code and models) would work here. I think it works quite well! It's much more forgiving than the original search engine. I don't have to guess what exactly they decided to label a particular item. But what I like even more is that it works quite well for…

I built a tool to roast landing pages with AI agents. I was gathering feedback from watching landing page roast videos, and figured out I could prompt LLMs to analyse a screenshot and roast based on the same criteria. It's not 100% accurate yet, but it has been really insightful when I've tested it on my own websites. Let me know what you think!

Hey HN, My workflow for any complex queries is to ask it in multiple AI chats (Gemini, Claude, o3,..) in parallel and then continue the conversation with the chat response that I found the most useful. I built a simple open source app that queries 10+ AI models at once and summarizes their answers with a selected combiner AI model. There's a GIF in the github repo that shows it in action. You can try it on your local machine: https://github.com/Nexarithm/multi_model_chat If you are interested, I also made a detailed blog post on technical details, feature of the personal…

I really struggle to keep my notes organised, and often can't make any sense of hand written notes after meetings. I did some experiments with Claude and ChatGPT where I blast random thoughts at them during a meeting or brainstorming session and then have them output a nice document that pulls it all together at the end. It worked incredibly well but it was a bit cumbersome to keep sending messages to the chat and telling the ai each time what to do. So I took the idea and built a tool, it makes it easy to throw random notes and voice recordings (images and document support on the way) and…

Hey HN, I built Upplai to help job seekers get quick, AI-driven feedback on their resumes and cover letters. The goal is to improve the chances of getting past Applicant Tracking Systems (ATS) and human recruiters. If you're job hunting, you can try it here: https://you.uppl.ai/login?invitation=ycombinator. Would love to hear your thoughts— does it actually help? What’s missing? Why I Built This: I founded Upplai because I’ve experienced firsthand how broken the hiring process is from both sides of the table. As a hiring manager, I was overwhelmed by the sheer volume of…
