Poesius vs auxi: AI PowerPoint Add-in Comparison for Consulting and Finance

If you're at a consulting firm or in finance looking for a PowerPoint add-in, you've likely encountered auxi. Trusted by 350+ institutions including 8 of the top 10 consulting firms, auxi has strong product-market fit with exactly the audience Poesius serves. This comparison explains the key differences—and why the tools serve different moments in the workflow.

What is auxi?

auxi is a productivity-focused PowerPoint add-in that helps consultants and finance professionals work faster in PowerPoint. Its core strength is slide manipulation—alignment tools, formatting shortcuts, distribution logic, and other operations that typically require tedious manual work.

auxi is genuinely excellent at what it does: it eliminates the manual formatting grind that consumes hours of analyst and associate time. The fact that 8 of the top 10 consulting firms trust it is a meaningful signal about its reliability and adoption.

What auxi is not: an AI content generation tool. auxi accelerates manual PowerPoint work. It does not generate slides from documents, apply narrative frameworks, or create analytical charts from data.

What is Poesius?

Poesius is an AI slide enhancement and generation platform that works inside PowerPoint. It takes rough content—notes, documents, data, sketches—and transforms it into consulting-grade slides with custom layouts, analytical frameworks, and brand compliance built in.

Poesius does not replace manual formatting shortcuts (though it reduces the need for them by generating properly designed slides from the start). It generates the content and design of slides from your input.

The Core Difference: Acceleration vs Generation

This is the fundamental distinction:

• auxi makes you faster at formatting slides you're already building manually
• Poesius generates the slides from your source material, applying consulting-grade design from the first output

They address different bottlenecks:

• The analyst who has already sketched slide structures and needs to format them quickly → auxi
• The associate who has source material (documents, data, research) and needs slide-ready content with proper design → Poesius

In practice, many power users will benefit from both: Poesius to generate the initial consulting-quality deck, auxi for rapid fine-tuning of specific elements.

Analytical Chart Types

Both tools support PowerPoint-native charts, but from different directions.

auxi provides shortcuts and formatting tools for charts you've already created. It helps you align, space, and style charts faster—but it doesn't generate the underlying chart structure from your analysis.

Poesius generates the analytical chart structure from your data or content description:

• Waterfall charts: DCF bridges, LBO waterfalls, sources-and-uses, variance bridges with proper positive/negative bar logic
• MECE issue trees: Asymmetric branching structures with custom depth and quantified impacts
• BCG matrices: Quadrant positioning with custom bubble sizing and annotations
• Harvey balls: Evaluation matrices with proper fill levels
• Mekko/Marimekko charts: Two-dimensional market share visualization
• Sensitivity tables: Two-axis sensitivity analysis with proper cell formatting

AI Capabilities

auxi does not offer significant AI content generation. Its intelligence is in formatting logic—alignment, distribution, spacing—not in generating slide content from source material.

Poesius is built on AI generation at its core:

• Document-to-deck: Feed in a PDF, Word document, or Excel model; get a structured consulting presentation
• Narrative generation: Applies Pyramid Principle, MECE, SCQA frameworks automatically
• Action titles: Generates insight-led slide titles, not descriptive ones
• MCP integration: Claude and other AI agents can generate presentations via Poesius's MCP tools
• REST API: Programmatic deck generation for automated workflows

Feature Comparison

| Feature | Poesius | auxi | |---------|---------|------| | AI content generation | Yes (full document-to-deck) | No | | Formatting shortcuts | Limited (slides come formatted) | Extensive (core product) | | Consulting chart generation | Yes (waterfalls, trees, matrices) | No (shortcuts for existing charts) | | Narrative frameworks | Built-in (Pyramid Principle, MECE, SCQA) | None | | Brand compliance | Full Slide Master fidelity | Works within PowerPoint formatting | | MCP / API | Yes | No | | Pricing model | SaaS (individual/team/enterprise) | Subscription per user | | Adoption in consulting firms | Growing | High (350+ institutions) | | Content marketing / SEO | Growing (this blog) | Minimal |

When to Choose Poesius

• You need to go from source material (documents, data, research) to slide-ready content
• You want AI to apply consulting narrative frameworks (Pyramid Principle, MECE, hypothesis-driven)
• You need analytical chart types generated from data (waterfalls, Mekko, issue trees)
• You want MCP or API integration for programmatic workflows
• You're building a consulting workflow where AI handles the first 80% of slide creation

When to Consider auxi

• Your team already does manual slide building and wants to accelerate the formatting step
• You need proven adoption with specific firm-standard PowerPoint templates
• The bottleneck is formatting efficiency, not content generation
• Your firm has already standardized on auxi and the switching cost is high

Can You Use Both?

Yes, and this is actually a strong workflow:

1. Use Poesius to generate the initial slide structure from your research, analysis, and documents—getting consulting-quality layouts and narrative structure in the first pass
2. Use auxi for any fine-tuning, alignment corrections, or element manipulation that needs manual precision

This combination eliminates both the content generation bottleneck (Poesius) and the manual formatting bottleneck (auxi).

Frequently Asked Questions

Is auxi being acquired or changing?

As of our last update, auxi is an independent company. We'll update this page if that changes.

Does Poesius have the same adoption across top consulting firms as auxi?

auxi has had a head start in this market and has deep penetration in MBB and Big 4 firms. Poesius is growing in the same segment. If your firm already has a standard tool, evaluate the incremental value of each.

Does Poesius replace the need for manual formatting?

Poesius's generated slides are designed to be properly formatted from the first output—correct fonts, colors, spacing, and chart types. In practice, some manual refinement is still typical for complex decks, but the volume of formatting work is dramatically reduced compared to building from scratch.
