Scanara vs Trail ML — EU AI Act Compliance Comparison
Scanara and Trail ML compared for EU AI Act work: rule-based code and document checks versus an AI governance platform.
TL;DR
Trail ML (the vendor writes “trail”) describes an AI governance platform with an AI registry and automated documentation, and says it is now part of Collibra. Scanara checks source code and documents against EU AI Act articles. The choice depends on whether you need an organisation-wide AI registry and policy workflow or checks of your own repositories.
Overview
As of 22 October 2026, the trail home page says: “Govern AI and software at scale by automating compliance busywork.” (original English wording) It lists an AI Registry (“Collect and classify AI use cases”), “Automated Documentation” and an EU AI Act self-assessment that identifies roles and risk classes.

Scanara checks source code with rule-based Semgrep rules in 12 programming languages and checks compliance documents with OPA rules in 8 EU languages. As of 24 August 2026, 66 of the 113 articles in Scanara’s coverage map have at least one automated rule. Guided assessments and drafts of Annex IV technical documentation cover further work. The customer decides and completes the results; passing a scan does not mean an organisation is compliant.

Questions to ask any vendor
Check whether it reads your source code
Some tools check the code itself; others rely on answers a person enters. Ask which applies, and which programming languages are covered.
Check where the results appear
Results can appear on pull requests, in a dashboard or in a report. Ask where engineers and compliance staff will see them.
Check what the vendor says about limits
No software makes an organisation compliant. Ask the vendor to state what its output does not cover and who makes the decisions.
Run a first scan on your repository
Connect a GitHub repository and scan it on the free plan. Plan limits are listed on the pricing page. Your team still decides and completes the assessments.
Scanara prepares evidence from your repositories
Scanara reads your connected GitHub repositories and runs rule-based scans for standard AI and machine-learning patterns. It can miss non-standard code. Separately, it generates draft documentation from templates and your assessment answers as evidence for your compliance work. You make the classification decisions.
