Chartbuddy is a data visualization extension for Google Slides that enables users to create professional-grade charts directly within their presentations. The company was founded in Amsterdam, the Netherlands, and is focused on bringing advanced charting capabilities to teams working in Google Workspace. Chartbuddy is available as a Chrome extension through the Chrome Web Store and is used by professionals across strategy consulting, finance, corporate planning, and other data-driven functions. Chartbuddy supports a wide range of chart types commonly used in business and strategic analysis, including waterfall, mekko/marimekko, stacked bar, clustered bar, 100% stacked bar, line, scatter, bubble, pie, and donut charts. Charts connect directly to Google Sheets and update in real time as underlying data changes, keeping presentations accurate without manual rework. All visual elements — colors, fonts, labels, and styles — can be customized to match company branding or presentation design. Charts embed natively into Google Slides files, so they work seamlessly with Google's built-in sharing and collaboration features. Collaborators with Chartbuddy installed can edit charts within shared presentations. The extension works in any Chromium-based browser, including Chrome, Edge, and Arc, and offers 10 free sessions to explore the full feature set before requiring a paid plan. Chartbuddy solves the gap between Google Slides' limited native charting and the advanced data visualizations that strategy, finance, and consulting professionals need. Users can build presentation-ready charts without leaving their slides or relying on external tools, saving time and maintaining visual consistency across their work. It is particularly valuable for teams transitioning from PowerPoint to Google Workspace who need to maintain the quality of their data storytelling without adding complexity to their workflow.
