A declared policy file stating whether AI systems may train on your content, retrieve it for live answers, and how they should attribute it if they do.
Gives you one place to state your position on AI training and indexing in plain, structured terms, for any crawler that chooses to check it.
A genuinely contested space: a 2023 Spawning.ai proposal, a separate 2026 IETF internet-draft, and a Guardian News & Media draft paper all use the name 'ai.txt' with different formats, and none has confirmed crawler support yet. Anything you actually need enforced belongs in robots.txt as well.
