+# AI Policy
+
+We welcome contributions from anyone, including people who use AI tools.
+
+However, we are volunteers. To protect our limited time and attention, we ask
+that all issues, pull requests, and comments come from a human who understands
+and takes responsibility for their contribution. AI can assist, but it shouldn't
+be the one asking for our attention.
+
+We do not allow unreviewed or fully autonomous contributions. If we wanted to
+prompt an AI or automate something, we could do that ourselves!
