In plain words
Claude Watermark Remover is a free browser-based tool that identifies and removes hidden traces left by chat interfaces in copied text, including invisible Unicode characters, zero-width spaces, and HTML class names. It displays exact locations and counts of findings, then cleans the text in one click with no account or uploads required. The tool addresses practical copy-paste artifacts that trigger AI detection systems, rather than attempting to mask writing style itself. Its engine is open source under the MIT license.

From the sources
Paste any text and see every trace a chat interface left in it: hidden HTML class names, zero-width characters, exotic spaces, typography. Each finding has a count and a position, because these are facts about the bytes, not a probability score. Clean it in one click. Free, unlimited, no account, runs in your browser so nothing is uploaded. It does not claim to detect Anthropic's statistical watermark, because nobody outside Anthropic can. The engine is MIT open source.
Free Claude watermark remover, checker and humanizer. Find hidden HTML and invisible Unicode, then humanize Claude text in one click.
Paste your Claude text. Strip hidden HTML, invisible Unicode and copy-paste fingerprints free, then humanize the word-choice pattern in one click. Markup you cannot see. Copying out of a chat interface carries HTML with it. Claude’s paragraphs arrive wrapped in class names containing “claude”, which land in whatever you paste into. This is what the AO3 detector catches, and it is the reason people get flagged, not their writing style. Characters that render as nothing. Zero-width spaces, joiners, byte-order marks, non-breaking and exotic spaces. Invisible on screen, obvious to anyone who looks at the bytes, and they survive most copy-paste routes. The prose itself. Curly quotes, em dashes…from claudewatermark.xyz

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

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…
