Where Cosmo stops

  • Works only in Claude, on your own Claude account.
  • Original writing only: no imitation of a living author, no lifted lines. Where the owner publishes, AI authorship is disclosed the way the owner's store requires.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
