Product comparison · Reviewed August 2026
A Microsoft 365 productivity add-in combining a customizable content library, charts, Excel links, brand controls, and text-focused AI assistance.
Different strengths, different operating models
Power-user is a broad Office productivity suite with a substantial slide and asset library, advanced charts, Excel links, templates, and formatting automation. Its AI assistant is currently centered on text rewriting and translation rather than full-deck generation from the company library. offgen is the more specialized AI presentation system.

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 4 for Power-user, 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. Power-user 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 Power-user when your main priority is: Office power users who want libraries, charts, Excel links, formatting tools, and brand controls in one add-in. Choose offgen when you need the stronger end-to-end system for recurring enterprise PowerPoint work: Organizations prioritizing AI-assisted deck creation, reusable company knowledge, and internal-agent access to approved presentation content.
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
offgen is operated by Aithera GmbH in Munich. Contracting, support, and the published legal framework are available for German and European customers.
02
offgen operates an independently certified information security management system and provides a trust center for security and procurement review.
