AI Jammer

Filters ::: filter_aijammer
Maintained by Astor Bizard
This text filter is an attempt to make copy-pasting of online exams subjects into third-party tools (e.g. AI-based tools) more difficult. The filter will inject random letters within texts. These letters will be made invisible on pages with CSS, but will be present to jam copy-pasting or automatic page reading.
