Protealpes
Free nutrition calculators and AI meal tools — no signup
What it does
Protealpes is a free nutrition workbench: 56 calculators (calories, protein, TDEE, macros, BMI, keto, activity burn, food-specific tools) plus AI tools that analyze meals from a photo or description. Unlike pages that hide the math behind a chat box, every calculator shows published formulas (Mifflin-St Jeor, activity factors, etc.). AI splits a meal into items, then maps them to a USDA-derived food table whenever a match exists — unmatched rows stay labeled estimated.
Estimate calories, macros, and meal nutrition with transparent formulas, USDA food data, and AI that explains the numbers — not invents them.
Get a calorie or protein number you can defend, then analyze the meal in front of you. Formulas stay visible. AI does not invent the math. Estimate a daily calorie target from body size, activity, and goal. Set a daily protein target from body weight and whether you are maintaining, training, building, or cutting. Split a calorie target into protein, carbohydrate, and fat grams. Upload a plate photo, describe what you ate, or both — then get calories and macros mapped to food data. Paste a recipe and a serving count to get per-serving calories and macros. Estimate the calories that hold your current weight at the activity you actually live — optional daily steps included. BMR and TDEE use…from protealpes.net

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…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
