Attestly vs AiActo

Both tools help produce EU AI Act Annex IV technical documentation. The difference is where the evidence in that documentation comes from.

AiActo is a guided-forms compliance platform covering the AI Act broadly — not just Annex IV, but classification diagnostics, an AI Act glossary and obligations reference, and multi-client management for agencies handling several clients' compliance. Its documentation generation works by walking you through each Annex IV section with an AI assistant that helps write the text based on what you type in — you supply the facts about your system, and it helps structure and phrase them. It's hosted in France with an EU-sovereignty angle, and works for any type of high-risk AI system, not just autonomous agents.

Attestly is narrower by design: it only handles Annex IV documentation, and only for AI agents specifically. Instead of you typing in what your system does, Attestly reads your agent's actual runtime traces (OpenTelemetry, LangSmith, AgentOps, MCP logs) and drafts the monitoring, human-oversight, and change-log sections directly from that evidence — each generated sentence links back to the specific trace event that justifies it.

Where each one fits better

If you need one platform to handle AI Act compliance across many different kinds of AI systems — not just agents — or you're an agency managing this for multiple clients, AiActo's broader scope and multi-client tooling covers ground Attestly doesn't try to.

If your system is specifically an AI agent that calls tools and makes autonomous decisions, and you want the monitoring and human-oversight sections of Annex IV backed by evidence from what the agent actually did — not a description you wrote yourself — that's the gap Attestly is built for. See why that evidence source matters for Annex IV specifically.
