EU AI Act applicability checker

Runs entirely in your browser. Your answers are never transmitted.

Answer a short questionnaire to find out whether the EU AI Act applies to your AI system, in what operator role, at what risk tier, and which obligations follow.

The engine is a direct port of a published EU AI Act compliance checker flowchart (version checker-2026-10-26), verified against 22 golden fixtures plus 35 shared parity vectors that the Python engine, the dashboard copy and the widget engine each replay in CI.

Loading checker…

Use from the CLI instead

Bash
# Interactive wizard (same questions, same engine)
opencomplai checker

# Open this page in your browser directly
opencomplai checker --web

# Serve the checker locally and open it (no internet required)
opencomplai checker --web --local

# Replay a saved answer set (for CI or repeatable demos)
opencomplai checker --answers answers.json -o json

# Export a full report
opencomplai checker --answers answers.json --export-all ./reports/eu-ai-act-result
PowerShell
# Interactive wizard (same questions, same engine)
opencomplai checker

# Open this page in your browser directly
opencomplai checker --web

# Serve the checker locally and open it (no internet required)
opencomplai checker --web --local

# Replay a saved answer set (for CI or repeatable demos)
opencomplai checker --answers answers.json -o json

# Export a full report
opencomplai checker --answers answers.json --export-all ./reports/eu-ai-act-result

What happens after the checker?

Once you know your role and risk tier, the next step is declaring a manifest:

Bash
# Let the checker pre-fill the manifest for you
opencomplai checker --answers answers.json --write-manifest system-manifest.json --intended-purpose "Screens job applicants"

# Or initialise interactively (runs the checker first)
opencomplai init --interactive
PowerShell
# Let the checker pre-fill the manifest for you
opencomplai checker --answers answers.json --write-manifest system-manifest.json --intended-purpose "Screens job applicants"

# Or initialise interactively (runs the checker first)
opencomplai init --interactive

Then run the compliance gate:

Bash
opencomplai check
PowerShell
opencomplai check
