Getting Started

What Knovari Sanitizer does

Knovari Sanitizer is a PowerPoint add-in that reads the slides you have open, uses AI to flag potentially sensitive content (client names, financial figures, named individuals, internal project codes, and similar), and then lets you decide what to redact, replace, or leave in place. The add-in produces a new, sanitized copy of your deck — your original is never modified.

Knovari is intended for use inside an organization’s Microsoft 365 tenant. All processing happens against documents the user has open in PowerPoint, under the user’s existing Microsoft sign-in.

Before you begin

You will need:

• PowerPoint for Microsoft 365 (Desktop on Windows or Mac).
• A Microsoft 365 work or school account in a tenant that has consented to Knovari Sanitizer (your IT administrator will do this once for the whole organization — see Admin consent below).
• An internet connection — Knovari Sanitizer is a cloud service.

The add-in does not require a license key, additional sign-in, or in-app purchase. Access is controlled by your organization’s subscription.

Installation

Install from AppSource

1. Open PowerPoint.
2. On the Home tab, click Add-ins → Get Add-ins.
3. Search for Knovari Sanitizer.
4. Click Add.
5. Accept the permissions dialog.

The Knovari ribbon group appears on the Home tab. You may need to close and reopen PowerPoint once.

Centralized deployment (for IT administrators)

If you are an administrator and want to deploy Knovari Sanitizer to all users in your tenant:

1. Sign in to the Microsoft 365 Admin Center at admin.microsoft.com.
2. Go to Settings → Integrated apps → Get apps.
3. Search for Knovari Sanitizer, click Get it now, and follow the deployment wizard to assign it to the users or groups you choose.
4. Users see Knovari Sanitizer in PowerPoint within a few hours of deployment.

Admin consent

Knovari Sanitizer signs users in with Microsoft single sign-on. The first time anyone in your tenant uses the add-in, your tenant administrator must grant admin consent for the following Microsoft Graph delegated permissions:

Permission	Why it’s needed
User.Read	Required by Office single sign-on to issue an identity token containing the user’s name and email.
openid	Standard OpenID Connect scope — confirms the user’s identity.
profile	Standard OpenID Connect scope — provides display name shown in the add-in UI.

Knovari Sanitizer does not call Microsoft Graph or read mail, files, or calendar data. These scopes are used purely to identify the signed-in user.

To grant admin consent, an administrator can use the URL provided in your onboarding email, or visit Microsoft Entra → Enterprise applications → Knovari Sanitizer → Permissions → Grant admin consent.

Your first sanitization — quick start

Once Knovari Sanitizer is installed and your tenant has consented:

1. Open a PowerPoint deck you’d like to sanitize.
2. On the Home tab, click Knovari → Sanitize. The Knovari task pane opens on the right.
3. Sign in with your Microsoft 365 account. The first time you do this, you’ll see your name appear in the task pane — there’s no separate Knovari password.
4. Choose a treatment profile (or use the default). A treatment profile is a saved set of rules — for example, the strings to use as placeholders (“[CLIENT]”, “[REDACTED]”) or which categories to apply automatically.
5. Click Run Analysis. Knovari reads your slides, sends the content to its analysis service, and returns a list of findings — each one is a piece of text or an image area it thinks may need attention.
6. Review the findings on the Overview screen. Click any finding to see its proposed treatment.
7. Apply or Reject each finding individually, or use the bulk actions to apply all findings of a given category at once. No change is written to your deck until you apply a finding.
8. When you’re happy with the review, click Generate File. Knovari creates a sanitized copy of your deck and downloads it. Your original is unchanged.

A first-time analysis on a 20-slide deck typically takes 90–180 seconds.

Privacy and data handling

Knovari Sanitizer processes the content of the deck you have open in PowerPoint to perform the analysis. Slide text and images are sent to a large-language-model subprocessor for classification under contractual terms that prohibit using your data to train models. Sanitized output and analysis results are retained server-side only for the period described in our privacy notice.

For full details on data collection, retention, subprocessors, and your rights as a user or as a customer organization, please read our Privacy Notice.
