Claude Watermark is a browser tool that finds what Claude leaves in your text when you copy from a chat: zero-width characters, odd spaces, stray HTML class names, all that good stuff. It shows each one with a count and a position, then strips them away on a click. What it can't do is detect Anthropic's real watermark, which went live across every Claude product this month, and Ofir Smolinsky spends his launch comment saying so, since nobody outside Anthropic has the key (yet).

Clipto is a search engine for video clips that live on your hard drive: it indexes dialogue, speakers, scenes and visual context, so you can find a moment by describing it in plain English. You can use the MCP side of things to point your favorite AI at a stash of clips and prompt it to generate something. To test it out, the team tried it with a pile of Elon Musk interviews and asked Claude what would be fun to make with them, and it chose Daft Punk's Around the World, found the moments where his words fit the song, and cut the video in FFmpeg.

Origin is Cursor's own Git host: repositories, pull requests, reviews, branch protections, and two-way sync with GitHub, so agents can open and update PRs without leaving the editor. Cursor has always been an editor sitting on top of someone else's code host, and that host was almost always GitHub, so this launch makes sense. It went into beta on Monday, four days after SpaceX closed its $60 billion purchase of Cursor's parent, and on a day GitHub was erroring on a fifth of its web traffic.
