Chartbuddy is a native charting add-on for Google Slides that adds advanced chart types like waterfall charts, marimekko charts, stacked bar charts — chart types that Google Slides doesn't support out of the box. It's designed as a think-cell alternative for Google Slides, bringing the same level of chart control and professional output to Google Workspace.

The add-on works directly inside Google Slides, meaning charts are native objects you can edit, resize, and format without leaving your presentation. Formatting controls cover individual data labels, segment colors, axis configuration, and chart spacing — the kind of granular control that consulting and FP&A teams need for client-ready decks and board presentations.

Chartbuddy also integrates with Google Sheets. Charts can be linked to a spreadsheet so that when underlying data changes, the chart in your slide updates automatically. This is particularly useful for recurring reporting workflows like monthly financial reviews or quarterly business updates, where manually rebuilding charts is a common pain point.

It's built for power users in consulting, strategy, corporate finance, and financial planning & analysis who work in Google Workspace but need chart types and formatting capabilities beyond what Google Slides and Google Sheets charts currently offer. If you're looking for a way to create waterfall charts in Google Slides, build professional marimekko charts without PowerPoint, or find a think-cell equivalent for Google Workspace, Chartbuddy is worth trying.
