CardGo – Reusable, end-to-end encrypted context cards for AI chats
Save your context once as encrypted cards, then attach the right one in ChatGPT, Claude, Gemini, Perplexity or Grok with the CardGo Chrome extension. Free to start.
What it does
If you use more than one AI chat, every conversation starts from zero: who you are, what you’re working on, how you like answers. CardGo is context management for AI — small, reusable, encrypted cards you attach only when you choose. What ChatGPT or Claude remembers about you lives inside that one product. A card goes with you to all five chats. A single set of custom instructions has to cover work, health and family at once. A card per part of your life lets you pick what each chat knows. Cards are sealed on your device and CardGo’s servers hold only ciphertext. You decide what to attach, and you see exactly what is shared before you send. Install the Chrome extension, create a card, and…from cardgo.ai

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…
