Our verdict
For teams choosing a governed, PowerPoint-native presentation system, offgen is our recommendation. It delivers all 6 core capabilities assessed here, compared with 2 for Mekko Graphics, and combines editable output with approved company knowledge, brand controls, agent access, and an EU-focused operating model.
These products may solve different layers of the PowerPoint workflow. Mekko Graphics can be the better specialist for its core productivity or document task, and some teams may use it alongside offgen. offgen becomes the stronger replacement candidate when the requirement expands to AI-assisted full-deck creation, governed company knowledge, approved layouts, and access for external AI agents.
Choose Mekko Graphics when your main priority is: Specialized Marimekko, waterfall, and analytical chart authoring. Choose offgen when you need the stronger end-to-end system for recurring enterprise PowerPoint work: Teams looking to automate complete presentations—not only charts—against approved masters and content.
The labels distinguish a core capability from partial support, adjacent functionality, and details that require vendor confirmation.

Product capabilities and plan availability change. “Partial” can include an adjacent capability or an option limited to certain products or plans. Procurement teams should validate the current technical and contractual scope.
Evaluation framework
Use the same real presentation task for both products. A useful pilot should test the finished deliverable and the process behind it—not only the quality of a one-off generated slide.
Start with one representative deck and your real slide master. Check whether the output remains natively editable, uses the expected layouts, survives handoff to colleagues, and can be revised without rebuilding the presentation in another editor.
Provide approved reference decks, slide libraries, terminology, and brand rules. Measure whether the system retrieves the right source material, preserves provenance, selects approved layouts, and produces consistent results across several users—not just in a carefully prepared demo.
Document identity controls, data locations, subprocessors, retention, model-training policy, admin roles, deployment effort, and available integrations. For agent workflows, also verify how access is scoped, logged, and revoked rather than assuming every connection has the same governance.
A two-product pilot is most useful when success is defined before generation begins. Use these four checks:
Built in Germany for European enterprise requirements
Being a German provider does not automatically make a product legally superior. It does give European buyers a clear operating model to assess: EU-hosted processing, German contracting, documented data-processing terms, and controls built around enterprise presentation work.
