I Built an AI That Matches Perfumes with Their Closest Twins
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…

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 recognizing fragrance profiles - Focused on making the experience smooth and intuitive Why It’s Cool: Finds "scent twins" across different brands Helps you explore new fragrances based on ones you already love Could even be useful for perfumers and fragrance enthusiasts alike I’d love to hear your feedback, ideas, and any thoughts on how to improve it! Check it out and let me know what you think.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
