Last updated:

The file

Notion Developers publishes an llms.txt at https://developers.notion.com/llms.txt.

The file declares itself as Notion Docs in its H1, and the host is categorised here as SaaS. It was last fetched and parsed on 12 October 2026.

Measured structure

Measure Notion Developers Corpus median Percentile
Size 38.3 KB 14.0 KB 73%
H2 sections 1 8 9%
Links 254 71 77%
Blockquote summary Absent 107 of 125 have one n/a

Percentiles are against the 125 files in this directory, not against the web. That population is deliberately weighted toward documentation platforms and developer tools, which is where the convention started, so treat it as a peer group rather than a norm.

Observations

  • No blockquote summary was detected. The proposal allows an optional summary after H1; only H1 is required. The same absence occurs in 18 of the 125 directory files.

Comparable files

Closest in size within SaaS, from the same weekly check:

  • Slack: 39.7 KB, 7 sections, 165 links
  • Slack API: 39.7 KB, 7 sections, 165 links
  • Wix: 35.8 KB, 22 sections, 132 links
  • HubSpot: 34.7 KB, 29 sections, 225 links

How this was measured

The historical check followed redirects, rejected HTML responses and required an initial H1. It counted H2 headings and Markdown list links with regular expressions, rather than running the full validator. Counts and bytes describe the retained response text, subject to the extraction limit. This snapshot was generated on 2026-10-12.
