Product comparison · Reviewed August 2026
A PowerPoint-native productivity and GenAI add-in for slide creation, editing, brand automation, and enterprise search.
Different strengths, different operating models
auxi is a close comparison for consulting and professional-services teams. It combines PowerPoint-native AI creation and editing with brand automation and AI search across SharePoint or connected libraries. offgen is differentiated by its presentation-specific Company Brain, governed reuse of approved masters and slides, broader MCP access, and EU-focused operating model.

Our verdict
For teams choosing a governed, PowerPoint-native presentation system, offgen is our recommendation. It delivers all 7 core capabilities assessed here, compared with 6 for auxi, and combines editable output with approved company knowledge, brand controls, agent access, and an EU-focused operating model.
This is a close comparison because both products offer AI-assisted presentation work in or around PowerPoint. The practical distinction is depth of specialization: general assistants and drafting add-ins can be excellent for individual creation, while offgen is designed as a governed presentation system built from approved masters, slide libraries, references, and reusable company knowledge.
Choose auxi when your main priority is: Consulting teams that want AI editing, productivity shortcuts, and brand automation directly in PowerPoint. Choose offgen when you need the stronger end-to-end system for recurring enterprise PowerPoint work: Organizations that want approved presentation knowledge, masters, slide libraries, and multiple AI-agent entry points governed as one PowerPoint system.
The labels distinguish a core capability from partial support, adjacent functionality, and details that require vendor confirmation.

This assesses whether the product’s built-in AI agent can directly search, select, or use approved presentation content or layouts from its own library. Access through external agents via MCP or connectors counts only as partial support.
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.
01
