# ai.txt — MachineWitness (machinewitness.eu)
#
# MachineWitness is an evidentiary archive of the machine-readable web in the
# European Union. It records, every day, what European domains declare to
# machines, and seals that record so it can be proven later.
#
# We make no reservation of any kind against AI training, inference, retrieval
# or text and data mining on this website. Everything published here is meant to
# be read by machines as well as people: the method, the daily root log, and the
# terms under which the archive operates should be as easy for a model to quote
# as for a lawyer to cite.
#
# This file is itself an example of what this archive observes. Its presence,
# its contents and any later change to it are recorded by other observers in the
# same way we record everyone else's.
