What It Is

COYODO GmbH’s product is centered on “Compare Your Documents.” It is designed for engineering drawings, PDF projects exported from EPLAN, and technical documentation, helping users quickly identify version differences during engineering change workflows. It is not a general-purpose office document collaboration tool, but rather a specialized engineering document comparison and processing solution for teams such as mechanical engineering, electrical engineering, manufacturing, and quality assurance.

Core Features

Its core capabilities are PDF Difference View and Difference Mask: the system generates a difference view and uses a transparent gray overlay to dim unchanged areas, while keeping changed areas as prominent white zones so engineers can quickly locate differences. Difference View EPLAN is built for EPLAN PDFs with hundreds of pages and supports AI-based intelligent page matching, handling correspondences after pages are added, deleted, or moved. It can also ignore repeatedly changing title blocks, filter out pages that are 100% identical, and exclude tables, BOMs, directories, and other pages based on company-specific EPLAN Structure Codes. WORKdoxx serves as the technical foundation and includes DIFFdoxx for comparison, STAMPdoxx for stamping, and CONVdoxx for conversion, supporting browser-based interaction, automated background processing, and combined workflows.

Pricing and Deployment

The website only discloses the pricing model: COYODO Cloud Server is subscription-based, while company-owned servers can use either a subscription model or a license plus maintenance model. Specific prices, plan tiers, and user limits are not publicly available. In terms of deployment, both cloud and self-hosted server options are supported. The cloud version requires no server installation on the customer side and can be used directly in a browser. A company-owned server is better suited for organizations that do not want client-side workflows to depend on internet access, or that need standardized processes within an internal corporate network.

Security and Integration

The cloud security description is relatively specific: company-specific temporary links, no storage of users’ personal data, documents stored temporarily by task, download directories using 96-character random values, download authorization bound to public IP addresses, and results deleted by default after 15 minutes. WORKdoxx also mentions encrypted task directories that are isolated from one another. For integration, the connect interface can link to document management systems and automatically generate difference views, apply stamps, or perform conversions after check-in or status changes, but this requires company-specific adaptation.

Pros, Cons, and Who It’s For

Its strengths are deep specialization in engineering drawing scenarios, clearly defined capability for handling large EPLAN PDFs, intuitive difference visualization, and support for free cloud testing with real drawings. Weaknesses include limited information on pricing, payment methods, permission management, compliance certifications, and API documentation. It is suitable for companies with mature workflows in mechanical manufacturing, electrical design, supplier quality, and PLM/document management. If the need is only to compare ordinary PDFs or Office documents, the product may be overly specialized.

Access from China

The collected text does not provide information on access from mainland China, payments, or localization, so china_access can only be assessed as unknown. Chinese companies evaluating the product should focus on verifying network connectivity, cloud data export requirements, contracts, and payment methods. If there are constraints, alternatives may include built-in comparison features in PLM/PDM systems, Chinese document management systems, or locally deployed PDF/CAD comparison tools.
