Short answer: for consulting decks built from your own material, choose Whyston. Plus AI is a capable AI assistant inside PowerPoint and Google Slides, but it does not document a consulting storyline, action titles, consulting charts or source citations. Whyston writes the argument and backs every number.

Where Whyston pulls ahead
- The argument, not just the slides. Whyston writes the SCQA storyline and an action title for every slide.
- Numbers a partner can check. Every figure labelled documented, derived or assumption, with a Figures and Assumptions page.
- Spreadsheets and data rooms. Whyston reads XLSX and CSV as evidence, not only documents.
- Consulting exhibits. Native waterfalls, Gantt roadmaps and annotated charts.
- A full slide editor. Move, resize and restyle every shape, text box and chart; smart layouts change a slide's look and feel in one click.
When Plus AI may be enough

- Formatting and rewriting slides you have already written.

- A partner, a board or an investment committee will ask where each number came from.
- You need the storyline and the action titles written, not only the slides.
- The team will keep working in PowerPoint after the first draft.
