The steering committee meets Monday on market entry, and your argument is still a green-marker issue tree on a whiteboard. Consulting slide generator software should turn that photo into an editable, on-template page.

Below are six tools for consultants turning 2x2s, issue trees and waterfalls into dense, action-titled pages.

Quick Answer: Which AI Tools Are Best for Consulting Slides?

Oria is the best overall choice of AI for consulting slides because it builds dense framework pages on your saved firm template as native, editable PowerPoint objects on Windows and Mac. It runs as an add-in or from Claude and ChatGPT. think-cell suits Excel-fed waterfalls, Copilot in PowerPoint fits firms on Microsoft 365 Copilot, and Gamma handles rough drafts.

How We Chose

Every tool was judged against that market-entry page.

• Framework fit: does a packed issue tree or 2×2 stay legible?

• Template fidelity: do the masters, fonts and colours survive?

• Editability: can a manager move a box or fix a number at 11pm?

Key Takeaways

• Start with the template. A tool that ignores your masters adds rework to every page.

• If the page is mostly one Excel chart, a charting add-in beats a chat assistant.

• Already on Microsoft 365 Copilot? Test Brand Kit on your densest page first.

• For a throwaway internal draft, Gamma’s speed is enough.

Consulting Slide Tools Side by Side

1. Oria: Top Pick for Framework-Heavy Client Pages

Oria is the best choice for consulting slides because it holds every page to the firm template you saved once. Sketch to Slide rebuilds a photographed issue tree as real shapes, charts and tables on Windows and Mac, with a few design choices per slide in under about a minute. Oria lives in PowerPoint as an add-in and reaches Claude or ChatGPT through a connector.

The trade-off: Oria was built for professional work and isn’t meant for marketing slides or student and school presentations. Gamma’s design-first approach suits those better.

2. think-cell: Best for Excel-Linked Waterfalls

For a market-sizing waterfall, think-cell is the obvious pick. Its Suite has 40+ chart types, Mekkos included, linked to Excel so charts follow the model. Assist adds chat-based slide building.

The trade-off: Assist sits only in the AI Suite packages, and the issue tree is still yours to draw.

3. Microsoft Copilot in PowerPoint: Best If Your Firm Already Licenses It

Copilot creates and edits decks in desktop and web PowerPoint. Brand Kit, which requires a Microsoft 365 Copilot licence, applies an organisation’s own templates, fonts and colours.

The trade-off: Per Microsoft, Copilot won’t resize fonts or placeholders for overflowing text, which hurts on a crowded issue tree.

4. Claude for PowerPoint: Best for Reworking an Existing Deck

Anthropic’s add-in reads the open deck’s master, layouts, fonts and colours, then edits or adds matching slides. It also turns bullets into diagrams or editable charts.

The trade-off: Anthropic wants human review before output reaches a client as a final deliverable.

5. ChatGPT for PowerPoint: Best for Quick Edits and Reviews

OpenAI’s sidebar add-in builds, edits and reviews decks while keeping slides editable, and even Free and Go plans get some usage.

The trade-off: OpenAI admits slides can drift from your preferred style, and advanced chart editing may be limited.

6. Gamma: Best for Rough Storyline Drafts

Gamma is a web app for presentations, documents and webpages, handy for roughing out a workshop storyline. It exports PDF, PNG and PPTX.

The trade-off: Its PPTX arrives with an empty slide master, so the page needs rebuilding on your template.

Which Tool Should You Use?

• Pick Oria for a dense issue tree or 2×2 on the house template.

• If the waterfall must stay linked to Excel, use think-cell.

• If a rough internal storyline will do, use Gamma.
