Airtight Reviews for Every Deck

Q: Why Is Consistency Check More Effective Than Generic AI Tools Like ChatGPT, Claude or Copilot?

Consistency Check is purpose-built for reviewing complex business and financial presentations. It analyzes relationships across slides, figures, tables, and narratives while surfacing findings directly within PowerPoint.

Stress-test numbers, narrative and formatting with AI-powered review for complex finance deliverables. Right inside PowerPoint.

Catch Errors Early

Automatically review decks to catch miscalculations and contradictory commentary, before they distract or derail the deal.

Cut Review Time in Half

Deliver polished, complex reports faster, with less reliance on outsourced review teams, without compromising accuracy.

Ensure Compelling Narrative

Maintain quality under tight deadlines and avoid last-minute changes, so teams focus their time on analysis and judgment.

Your Second Pair of Eyes.
Only Sharper.

Powerful AI catches data discrepancies, calculation errors, and narrative mismatches that even the best reviewers miss. In half the time.

Deep Deck Review in Minutes, Inside PowerPoint

Run AI Consistency Check on entire decks or just selected sections, right inside PowerPoint on Windows, Mac, and online.

In minutes, it interprets documents like due diligence reports and IMs to spot miscalculations, contradictions, and inconsistencies across text, tables, charts, and visuals, grouping issues into clear categories so you know what to check first.

Pinpoint Every Issue, Track Every Fix

No more hunting for where an error lives. AI Consistency Check locates issues precisely on the slide and lets you jump straight between the slides an inconsistency affects. Mark each issue as solved in the pane to track resolution at a glance, so managers spend less time cross-checking and teams avoid late-stage rework.

Review in the Pane, Delegate in Comments

Every issue is handed to you first in a dedicated review pane, each with a clear, detailed rationale. Turn any issue into a PowerPoint comment to delegate resolution to colleagues, including those who don’t have UpSlide. Prefer to work across two screens? Export a PDF report that anchors errors in time and against a specific document, giving you a fixed reference to review against.

Review PDFs, Not Just PowerPoint

Consistency Check also runs directly on PDF files so buy-side and deal teams can pressure-test teasers, information memorandums, and due diligence reports the moment they land, without waiting for a PowerPoint version. Spot errors earlier in the process, on the exact documents you actually receive.

Don't Take Our Word for It. Take Theirs.

Consistency Check flagged differences in reported cash levels, even though these stemmed from different sources and calculation methods. It is remarkable that the AI picked this up, even in data presented in image format.

FAQs

What Is AI Consistency Check?

AI Consistency Check is an AI-powered review and audit tool that automatically detects inconsistencies, miscalculations, and narrative conflicts across financial presentations and documents, directly inside PowerPoint. It reads numbers, narrative, tables, charts, and text regardless of format (image, linked table, or plain text) and flags issues early so teams fix them before they affect decisions or reach external review. It’s built for finance teams handling investment memorandums, due diligence reports, pitchbooks, and fund reports.

How Does AI Consistency Check Help Teams Act on and Share Results?

Errors are grouped into clear categories, flagged precisely on the slide, and linked so you can navigate between every slide an issue affects. You can mark issues as solved to track resolution at a glance, export a PDF report to anchor findings against a specific version, and run Consistency Check directly on PDF files, which is useful for reviewing teasers, IMs, and DD reports received as PDFs. It runs on Windows, Mac, and PowerPoint online.

Why Is Consistency Check More Effective Than Generic AI Tools Like ChatGPT, Claude or Copilot?

Generic AI tools aren’t designed to reliably review complex financial decks. In our testing on a 60-slide financial presentation, ChatGPT and Claude caught only 20–25% of issues, often missing cross-slide inconsistencies. Copilot performed slightly better but generated significant noise and still missed critical errors. AI Consistency Check caught 4x the inserted errors in the same deck, twice as fast, requiring no prompting and flagging issues directly in PowerPoint. It’s purpose-built for financial documents and runs a multi-step pipeline of several AI and non-AI passes that cross-check content, filter duplicates, and rank issues, rather than a single one-shot prompt.

Can It Be Used With Files From External Sources, or in PDF?

Yes. Whether a deck was created internally or received from an external party, Consistency Check analyzes it and surfaces issues early, helping your team validate incoming materials before advancing reviews. It also runs on PDF files, so buy-side and deal teams can pressure-test teasers, information memorandums, and due diligence reports as soon as they’re received, without waiting for a PowerPoint version.

What Is UpSlide AI Consistency Check Compatible With?

AI Consistency Check runs as an add-in across Windows, Mac, and PowerPoint online, and requires IT deployment of the UpSlide JS add-in. Once deployed, users also gain access to other JS-based features. It’s part of the AI Package and consumes AI credits. For the full UpSlide suite, UpSlide can be installed on any machine running Microsoft Windows 10 and 11 (x32 or x64) and Microsoft Office 2016, 2019, or Office 365 Current Channel.

Is My Data Processed Securely?

Security is foundational to everything we build. UpSlide is SOC 2 Type II certified, ISO 27001 compliant, and built to meet the stringent requirements of global financial institutions. Your data is encrypted in transit and at rest, and we never use client data to train AI models. We can also support private cloud or on-premise deployments for firms with additional requirements.

Which LLMs Power Consistency Check, and Do You Train on My Documents?

Consistency Check currently uses Azure-hosted OpenAI models within a multi-step pipeline, and we continue to evaluate other models to maximise performance and completeness. We never train models on your data. Instead, we improve the system through prompt and pipeline optimization and a real-world validation loop, running the feature on benchmark decks and comparing outputs, so accuracy, speed, and cost keep improving without your documents ever being used for training.
