Key differences

enaio (OPTIMAL SYSTEMS)

enaio: classic DMS with named-user licenses and partner rollout. Filing and workflow are the core — API access and AI extraction follow edition and project.

PaperOffice AI

Document platform with API: result in the archive, one credit balance, hosted in the EU, MCP for AI agents.

Three decision axes

What happens to the result?

The result from enaio stays in that product context. PaperOffice keeps extraction and archive on the same document.

Contracts & billing

enaio is introduced as a partner project — without a public price list. Extraction or signature can have their own contracts. PaperOffice bundles this in one account.

Where do your data run?

enaio stores and organizes files in its own model — residency depends on edition and hosting. PaperOffice runs its own EU servers and keeps extraction plus audit-proof filing together.
