How we rate AI tools
Every trust band is an assessment of what is publicly verifiable, as of the date shown, with sources. It is not a number we invent.
What the band means
Each tool shows one band: Higher, Medium, Lower, or Unrated. We publish a band, not a precise number, because a band plus our reasons and sources is a fair, defensible assessment, while a single figure on a named product is a claim a vendor could dispute. Areas we cannot verify are left Unrated and pulled out of the calculation, so a tool is never marked down for information we could not find. If we cannot verify at least half of the four areas, the tool stays Unrated.
The four areas and their weight
Data location and compliance carry extra weight because our customers are security and compliance teams.
Dated, sourced, and correctable
Every rating carries the date we checked it and links to the public sources behind it. If you make one of these tools and think a rating is wrong, request a correction.
