Different strengths, different operating models

How Power-user and offgen differ

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

Why offgen is the stronger choice than Power-user

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.

Choose Power-user when…

  • Analysts and consultants need Mekko, Sankey or Gantt charts, Excel-linked maps and live Excel-to-PowerPoint links for data-heavy slides they build themselves.
  • You want an affordable productivity add-in for PowerPoint, Excel and Word, with a permanent free plan and a 90-day trial before anyone buys.
  • Your team has no curated asset library yet and benefits from a large ready-made catalog of slide templates, icons, maps and pictures.

Choose offgen — our recommendation

  • Organizations prioritizing AI-assisted deck creation, reusable company knowledge, and internal-agent access to approved presentation content.
  • Your procurement case benefits from an EU-hosted service operated by a German company, an ISO/IEC 27001-certified ISMS, a DPA, and a policy not to train models on customer content.

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.

Key differences

How Power-user and offgen differ

Charts, maps and Excel links vs. deck generation

Power-user adds chart types PowerPoint lacks, such as Gantt, Mekko, Sankey, Tornado and Dumbbell, 350 editable maps that connect to Excel data, and live Excel links for one-click report updates. For analysts building data-heavy slides by hand, this charting toolkit goes further than offgen, which is not positioned as a charting add-in. offgen focuses on generating complete, editable decks from approved templates and on refreshing recurring reports while preserving structure and wording.

Text AI assistant vs. AI built on company content

Power-user's AI Assistant, based on GPT-4.1-mini through the OpenAI API, translates, rephrases, shortens, expands, fixes grammar and changes the tone of selected text; it does not generate slides. Power-user states that this data is not used for training but may be stored by OpenAI for up to 30 days. offgen generates slides and full drafts from your Company Brain, with the managed service and standard language models hosted in the EU.

Ready-made content catalog vs. your approved knowledge

Power-user ships 1,000 slide templates, 10,000 vector icons and flags, millions of pictures and company logos, and centralized template management with an admin portal on Premium Entreprise. That ready-made catalog helps teams without their own asset base. offgen is built around your own material: approved masters, slide blocks, CVs, project references and brand rules, with lockable elements and an AI slide review that checks drafts against those standards.

Power-user pricing

Power-user offers a Free Forever plan, a Premium plan listed at EUR 240 per user per year (billed annually) and a Premium Entreprise plan on quote, plus a 90-day free trial of all Premium features without a credit card. offgen is licensed per organisation with pricing on request.

A practical pilot checklist

A two-product pilot is most useful when success is defined before generation begins. Use these four checks:

  1. 1Generate the same 10-15 slide deck from an identical brief and approved source pack.
  2. 2Ask a second user to edit, update, and hand off the resulting PowerPoint without vendor help.
  3. 3Record brand corrections, unsupported layouts, manual cleanup time, and factual source errors.
  4. 4Have IT and procurement validate the exact plan, deployment model, security evidence, and contract terms.

Built in Germany for European enterprise requirements

offgen for European teams

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

German operator

offgen is operated by Aithera GmbH in Munich. Contracting, support, and the published legal framework are available for German and European customers.

02

ISO/IEC 27001

offgen operates an independently certified information security management system and provides a trust center for security and procurement review.

03

EU-hosted, no model training

Customer content is processed in an EU-hosted environment and is not used to train AI models. A data processing agreement is publicly available.

Frequently Asked Questions

The practical questions to ask before choosing a presentation platform.

Yes, focused on text. The Power-user AI Assistant can translate, rephrase, shorten or expand, convert to bullet points, fix grammar and change the tone of selected text, and the library offers AI image generation. It runs on GPT-4.1-mini through the OpenAI API and processes selected text only. It does not generate slides or decks, which is where offgen's AI drafting from approved templates differs.
Power-user lists Premium at EUR 240 per user per year, billed annually by default. A Free Forever plan gives permanent access to part of the content library, all pictures and the Excel functions. Premium Entreprise, with central customization, an admin portal and dedicated training, is quoted on request, and teams of ten or more can arrange custom billing cycles or usage-based billing.
Often, yes. Power-user is a manual productivity layer with charts, maps, Excel links, alignment and formatting tools, while offgen generates and reviews decks from approved company content. A team could draft a proposal in offgen and then refine a Mekko chart or an Excel-linked map with Power-user. Test both add-ins on your standard PowerPoint setup and check that ribbon space and brand settings do not conflict.
No. Power-user may be the better fit when your priority is: Office power users who want libraries, charts, Excel links, formatting tools, and brand controls in one add-in. offgen is designed for a different priority: Organizations prioritizing AI-assisted deck creation, reusable company knowledge, and internal-agent access to approved presentation content.
Verify the contracting entity, processing locations, subprocessors, international-transfer mechanism, DPA, retention, model-training policy, security certifications, and which controls apply to your exact plan. offgen publishes its German operator, DPA, EU-hosting position, ISO/IEC 27001 status, and no-training policy for this review.
