How to build EU AI Act evidence across your AI tools
How to produce the documentation the EU AI Act expects across every AI system you use, Microsoft Copilot and non-Microsoft tools alike: a per-tool record of what it does, the data it touches, who owns it, and when it was last reviewed.
EU AI Act evidence across AI tools is the documentation showing that each AI system your organization uses has been risk-classified, inventoried, and overseen as the regulation requires, spanning Microsoft Copilot and non-Microsoft tools alike. It centers on a per-tool record: what the system does, the data it touches, who owns it, and when it was last reviewed, assembled into auditor-ready reports rather than reconstructed under audit pressure.
The EU AI Act does not care which vendor an AI system came from. Its obligations attach to how a system is used and the risk it carries, which means the evidence has to span Microsoft Copilot and every non-Microsoft tool your teams run, not just the Microsoft surface most tooling stops at.
That reframes compliance as an inventory-and-record problem. Know every AI system, classify each by risk, document what it touches and who owns it, and keep that current through owner attestation. The steps below build the evidence continuously so an audit becomes a handover rather than a reconstruction.
Steps
-
Inventory every AI system
Start from a complete inventory of the AI tools and agents in use, Microsoft Copilot and non-Microsoft vendors, because you cannot produce evidence for systems you have not catalogued.
-
Risk-classify per the Act
Classify each system against the EU AI Act's risk tiers, so obligations and documentation depth match the risk each system actually carries rather than applying one level to everything.
-
Document data and ownership
For each system, record what it does, the data it touches, and who owns it. This per-tool record is the substance of the evidence the Act expects.
-
Run owner attestation
Have owners periodically attest that their AI systems still match their documented purpose, data reach, and risk class, so the evidence stays current instead of aging into fiction.
-
Produce auditor-ready reports
Assemble the inventory, classifications, and attestations into reports an auditor can follow from obligation to proof across every vendor, turning the audit into a handover.
