Simple Unmark
Clean AI text without changing its meaning
What it does
Simple Unmark removes hidden Unicode controls and formatting artifacts from AI-generated text, then rewrites syntax and phrasing to reduce probabilistic watermark signals while preserving facts, numbers, proper nouns, tone, and intent. It is free to try, with optional one-time credit packs and no subscriptions.
Paste AI-generated text to remove hidden Unicode artifacts or rephrase statistical watermark patterns. Review the result, then copy clean text.
Paste your text. We clean hidden characters and rewrite statistical watermark patterns automatically. Use with AI agents. When Site tools are available in the ChatGPT desktop app's built-in browser, Codex or ChatGPT Work can place text here for review, ask permission before starting the standard clean, and return the finished text to your conversation. The original, result, removed characters, mode, and warnings stay visible on this page. Gemini and Claude both mark text through token choices rather than hidden characters, so rewriting is what addresses them. Copy-paste artifacts are literal characters, so those are removed exactly. Every clean does both. There is no watermark character to…from simpleunmark.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…

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…
