camocat is a search engine deoptimization tool, camouflaging text from bots in a form that’s readable to humans but less readable to computers.

It works by replacing English characters with Unicode equivalents from the Greek, Coptic, and Cyrillic alphabets. It also interleaves zero-width space characters for additional obfuscation. The intent is that the output text looks the same to the human eye, but is encoded completely differently.

Camouflaged text may be harder for search engines to index, and more resistant to AI-driven censorship, sentiment analysis, and targeted advertising.


Usage is similar to cat, reading from a provided file or standard input, and writing to standard output.
