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
Mekko Graphics exists to replace several basic charts with one analytical chart. It offers more than 30 chart types, including Marimekko, bar mekko, waterfall, cascade, bubble and Gantt, with axis breaks, CAGR columns, data rows and growth lines. Strategy and market-sizing teams rely on that depth, and offgen does not try to match it. offgen produces native PowerPoint charts and tables as part of a complete deck built from your master and approved content.
Mekko Graphics lets teams save standard formats, colour palettes and a chart gallery, and enterprise licences add custom branding, so charts look consistent across analysts. Those controls apply to charts. offgen applies brand rules to the whole presentation: layouts, placeholders, typography, spacing and bullet styles from your master, plus locked elements such as disclaimers and methodology pages, and an AI slide review before the deck reaches a partner or client.
Mekko Graphics is a manual, analyst-driven tool: you enter data or connect charts to Excel and design each chart yourself, and its product pages do not describe AI features. It runs as an add-in for PowerPoint and Excel on Windows, with a PowerPoint add-in for Mac. offgen adds AI drafting from a briefing, reuses approved slides, CVs and references, and can be called by external assistants through MCP, while your team keeps control over the final numbers.
Mekko Graphics is sold as an annual subscription: a single licence is listed at USD 399 per user per year (renewing at USD 299), volume licences for 4 to 100 users start at USD 249 per user per year, and enterprise licences for 101 or more users are USD 149 per user per year. A 30-day free trial with full functionality is available. offgen is licensed per organisation with pricing on request.
