Our verdict

Why offgen is the stronger choice than Deckary

For teams choosing a governed, PowerPoint-native presentation system, offgen is our recommendation. It delivers all 7 core capabilities assessed here, compared with 3 for Deckary, 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 Deckary when your main priority is: Individuals who want AI, charts, shortcuts, and icon utilities in one Office add-in. Choose offgen when you need the stronger end-to-end system for recurring enterprise PowerPoint work: Organizations that need approved company knowledge, masters, slide libraries, and AI-agent access governed as one enterprise system.

Choose Deckary when…

You work as an independent consultant or small team and want AI slides, Excel-linked charts, icons and shortcuts at a published monthly or yearly price you can buy today.
Your analysts need one add-in that also builds financial models in Excel and drafts documents in Word, not only presentations.
You mainly need waterfall, Mekko, Gantt and other consulting charts that stay linked to Excel data, and central governance of company content is not a requirement.

Choose offgen — our recommendation

Organizations that need approved company knowledge, masters, slide libraries, and AI-agent access governed as one enterprise system.
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 Deckary and offgen differ

Consulting toolkit vs. governed Company Brain

Deckary bundles an AI slide builder with a consulting production kit: 140+ pre-built slide templates, 2,000+ icons, alignment shortcuts and a personal library where each user saves slides for later decks. offgen starts from the organisation instead of the individual. Approved masters, reusable slide blocks, CVs and project references are maintained centrally, tagged by industry, capability and language, and used as source material whenever a person or an agent drafts a new deck.

Excel-linked consulting charts are Deckary's strength

Deckary ships consulting chart types such as waterfall, Mekko/Marimekko, Gantt and stacked bar, all linked to Excel so they update with the data. Its Premium plan adds an AI agent for financial models in Excel and for documents in Word. offgen does not position itself as a chart engine. It can refresh figures and charts in recurring reports, but teams that work in Mekko and waterfall charts every day will find Deckary's chart toolkit deeper.

Consistency audits vs. rules and locked elements

Deckary's /consistency command audits fonts, colors and spacing across a finished deck and fixes deviations. offgen applies brand rules during generation: the master is translated into allowed colors, fonts, layouts and placeholders, and protected elements such as legal pages, disclaimers, logos or methodology diagrams can be locked so neither users nor AI change them. Both products offer MCP access for external agents, so the real question is which content and rules those agents can reach.

Deckary pricing

Deckary offers a 14-day free trial without a credit card. Starter is listed at USD 15 per month or USD 120 per year, Premium (AI in PowerPoint, Excel and Word) at USD 19 per month or USD 180 per year, and Team at USD 29 per seat per month with a minimum of five seats. 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:

1Generate the same 10-15 slide deck from an identical brief and approved source pack.
2Ask a second user to edit, update, and hand off the resulting PowerPoint without vendor help.
3Record brand corrections, unsupported layouts, manual cleanup time, and factual source errors.
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.

German operator

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

ISO/IEC 27001

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

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.

Deckary lists Starter at USD 15 per month (USD 120 per year), Premium at USD 19 per month (USD 180 per year) and Team at USD 29 per seat per month with at least five seats. AI for PowerPoint, Excel and Word starts with Premium; Starter covers templates, icons, shortcuts and the browser editor. The 14-day trial needs no credit card. offgen is licensed per organisation, with a tailored proposal after a demo.

Deckary describes itself as Netherlands-based and GDPR-compliant, with encryption in transit and at rest and Standard Contractual Clauses for transfers outside the EEA. Its public pages do not name a hosting region or the AI model providers it uses. offgen is operated by Aithera GmbH in Munich, hosts the service and its standard language models in the EU, runs an ISO/IEC 27001-certified ISMS and does not train models on customer content.

Yes. Both run as PowerPoint add-ins, so a team could keep Deckary for Excel-linked Mekko or waterfall charts and use offgen to generate proposals and reports from approved masters and references. Check the overlap first: both create slides with AI and both offer MCP connections for agents, so two systems mean two places where users and agents draft content and two sets of rules to maintain.

No. Deckary may be the better fit when your priority is: Individuals who want AI, charts, shortcuts, and icon utilities in one Office add-in. offgen is designed for a different priority: Organizations that need approved company knowledge, masters, slide libraries, and AI-agent access governed as one enterprise system.

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.
