Cardano founder launches free tool to remove Anthropic's AI watermarks

Some computer programs that write text now add a secret mark, like a hidden stamp, so people can tell a computer wrote the words.

A company called Anthropic started doing this with its writing program, Claude.

A man named Charles Hoskinson made a free tool that can remove these secret marks.

The mark is not a visible label; it is a hidden code that changes how the program picks words.

Hoskinson's tool can clean off a 'Co-Authored By' tag, fix pictures, and rewrite the words using a different computer program so the mark disappears.

The tool will not use Claude or Gemini to do the rewriting, because that would put the mark right back on.

Hoskinson says the marks could cause problems, like making it unclear who really owns the words.

He worries someone who only checks spelling with Claude could later be told their writing was made by a computer.

Hoskinson wants people to ask an important question: who owns a sentence after a computer program helps write it?
