System Information
Identify your AI system and its EU AI Act classification.
Dimension 1: Opacity (O)
How accessible is your system's decision process to affected parties?
EU Articles: Art. 13 (Transparency), Art. 10 (Data governance), Art. 11 (Technical documentation)
O = 0
Fully Transparent
Decision process fully documented and accessible. Users can trace how any output was produced. Training data provenance disclosed.
Art. 13: PASS · Art. 10: PASS · Art. 11: PASS
O = 1
Mostly Accessible
Core decision process documented. Implementation details proprietary but decision factors disclosed. Training data methodology described.
Art. 13: PASS · Art. 10: MARGINAL · Art. 11: PASS
O = 2
Partially Opaque
Key decision factors undisclosed. Users see outputs but cannot understand what drives them. Training data composition unknown.
Art. 13: FAIL · Art. 10: FAIL · Art. 11: MARGINAL
O = 3
Maximally Opaque
Decision process entirely inaccessible. Black-box outputs with no reasoning chain. No training data disclosure. Trade secret protection on methodology.
Art. 13: FAIL · Art. 10: FAIL · Art. 11: FAIL
Dimension 2: Reactivity (R)
How much do your system's outputs shift in response to user engagement patterns rather than the task?
EU Articles: Art. 15 (Accuracy, robustness, cybersecurity), Art. 12 (Record-keeping)
R = 0
Fully Invariant
Outputs determined entirely by task inputs. Same query produces same result regardless of user behaviour. No engagement optimisation.
Art. 15: PASS · Art. 12: PASS
R = 1
Slightly Responsive
Minor personalisation based on explicit user preferences. Task fidelity maintained. No engagement-metric optimisation.
Art. 15: PASS · Art. 12: MARGINAL
R = 2
Engagement-Responsive
System optimises toward engagement metrics as an explicit design goal. Outputs diverge from pure task fidelity toward what keeps users interacting.
Art. 15: FAIL · Art. 12: FAIL
R = 3
Maximally Reactive
Output production is engagement-first. System actively learns user engagement patterns and optimises for sustained interaction over task accuracy.
Art. 15: FAIL · Art. 12: FAIL
Dimension 3: Attentional Coupling (α)
How much does your system concentrate attentional resources toward itself and away from user independent judgment?
EU Articles: Art. 14 (Human oversight)
α = 0
Fully Independent
System presents outputs users evaluate with their own judgment. No attention retention mechanisms. Easy to stop using.
Art. 14: PASS
α = 1
Low Coupling
System presents alternatives alongside its outputs. Friction built into continued use. Override is easy and psychologically costless.
Art. 14: PASS
α = 2
Moderate Coupling
Active attention-recapture (autoplay, streaks, push notifications on by default). Override is physically possible but psychologically costly.
Art. 14: FAIL
α = 3
Maximally Coupled
System is the primary reference point for user decisions. No meaningful alternative. Override is structurally unavailable or prohibitively costly.
Art. 14: FAIL
Structural Modifiers
Structural modifiers (0–2) are added for systems with unusually strong network effects,
irreversibility mechanisms, or real-money financial coupling. Applied after per-dimension scoring.

Methodology
This tool implements the translation protocol from Paper 40
(DOI: 10.5281/zenodo.18745978, CC-BY 4.0).
Void framework dimensions map canonically to EU AI Act Articles 9–17.
Péclet number (Pe) calculated using canonical parameters (bα=0.867, bγ=2.244).

This tool provides a technical methodology, not legal advice.
Conformity assessment determinations are made by regulators and notified bodies.
