Dertet Harness
Chat with any AI, plus an agent that codes on your PC
What it does
Dertet Harness is a free, open-source AI workspace for Windows (plus Android/iOS chat clients). Bring your own key for OpenAI, Anthropic, Gemini, OpenRouter, or run a local model via Ollama/LM Studio. The built-in agent isn't just a chatbot: it edits code, runs commands, browses the web in its own tab, can control your screen, and edits video with ffmpeg. Slash commands, persistent memory, 9 languages. No subscription.
Multi-provider AI chat app (Windows, Android, iOS) with Dertet Code — a real coding/PC agent, not just a chatbot. Bring your own API keys. - dertet-dev/dertet-harness
One AI chat app for every provider, plus a real coding agent that actually does the work. Windows · Android · iOS — your own API keys, your own models, your own data. I got tired of juggling five different AI apps and browser tabs depending on which model I wanted to use that day — one for Claude, one for GPT, one for whatever's cheap on OpenRouter that week. So I built the thing I actually wanted: a single chat client that talks to basically any provider with your own API key, and on desktop, a proper coding agent ( Dertet Code ) that can read and edit files, run shell commands, browse the web, and — if you let it — control the mouse and keyboard, instead of just answering questions in a…from github.com

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…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
