What the file is
The AI Companion is one JSON file. It is the same month as the PDF of the TrueCOLA Margin Report. Every number in it comes from that month's published figures. Nothing new is calculated.
The Companion file is not a public download. Request it on the Download Report page. That is the same form as the PDF. We email a one-time link.
Rows are labeled. An AI reads the file as data, not as a scraped page or a PDF.
The file you receive is named TrueCOLA Margin Report 2026-07 (AI Companion).json.
