Does postman.com block AI crawlers?

Can AI assistants cite postman.com?

• ChatGPT search: its search crawlers may read the site

• Perplexity: its search crawlers may read the site

postman.com opts out of AI training by ByteDance. Training crawlers and answer crawlers are separate: blocking training doesn't by itself remove a site from AI answers.
