Letsignit Slides

Every presentation, on-brand. Right inside PowerPoint.

Your brand guidelines deserve more than a SharePoint folder. Letsignit Slides brings them inside PowerPoint and keeps them enforced: the right template, the latest content, the right disclaimer, just one click away.

The reality

PowerPoint is one of your largest brand surface. And your least controlled.

Every day, thousands of presentations leave your company. Client proposals. Board decks.
Partner pitches. Internal reports. Each one a brand moment and most of them, off-brand.

1
Templates exist. Nobody uses them.
You published brand templates on SharePoint. You sent the announcement. You trained the teams. And employees still open a blank slide, or reuse last quarter's deck from a colleague.
2
Every deck is a brand exception.
Wrong logo size. Off-brand blue. Missing footer. Outdated tagline. Every employee improvises a slightly different version of your brand, and that version leaves your company every single day.
3
Brand Managers are chasing ghosts.
Your team spends more time correcting slides than building the brand. Manual enforcement doesn't scale. By the time you catch a drift, it's already in front of a client.
Brand guidelines that aren't
enforced are just suggestions.
The shift

From brand guidelines

to brand governance.

Better templates aren't the answer. Brand governance is. Letsignit Slides delivers the last mile: your brand, enforced on every slide, the moment PowerPoint opens.

The platform

Brand governance that runs itself.

Letsignit Presentations doesn't replace PowerPoint.
It makes PowerPoint finally work for your brand.

One console. Every brand, every BU, every country.

When your brand spans multiple BUs, regions, or entities, governance can't be manual. Letsignit Slides gives Brand teams one console to centralize, assign, and deploy decks at scale, with no IT dependency.

  • Import & centralize every PowerPoint file in one place.
  • Assign decks by user, team, country, role, or subsidiary synced from Azure AD / Entra ID.
  • Analyze & optimize: AI refines your imported themes to PowerPoint best practices, so they're easy for teams to use and ready to deploy.

Brand rules,applied by default.

Real enforcement, not just distribution. Brand rules are applied at the application level, not at the trust level so employees can't improvise, even by accident.

  • Validated, ready-to-use templates
  • Lock colors, fonts, layouts, disclaimers, and footers
  • No more off-brand slides
  • Rebrand in minutes: publish new, deprecate old, propagate everywhere.

A full library of brand-approved assets, inside PowerPoint.

Beyond themes, your teams need ready-made building blocks. Letsignit Slides puts a curated library at their fingertips — right inside PowerPoint — so they spend their time on the message, not on hunting for the right asset.

  • Drop in pre-built slides for every recurring use case.
  • Pull approved icons, illustrations, logos, and brand visuals on demand.
  • Skip the search: every asset on-brand, approved, and current.

Right where your teams already work.

The Letsignit Slides add-in lives inside PowerPoint itself. Your assigned brand theme and asset library are one click away. No new tool, no behavior change, no extra login.

  • One click from the Design tab: the add-in sits exactly where teams expect it.
  • A certified Add-in, co-built with Microsoft engineering, works on Windows, Mac, and PowerPoint online.
  • Your assigned theme, always at hand
  • No more SharePoint hunt

Why it matters

Your most powerful brand channel isn't a campaign. It's your people.

Every email, every meeting, every connection is a brand impression, multiplied by every employee, every day.

No channel matches that scale, and none matches that humanity.

Enterprise-grade, by design.

Letsignit enhances and elevates our brand image, making it more dynamic. With the platform, we can create both internal and external campaigns to highlight events or promotions.

Letsignit is a tool that is both simple and powerful for standardizing employees' email signatures and also treats the signature as a new media. It can be used as a low-cost acquisition channel. All of this integrated into Microsoft Office 365.
Carole Benichou
Director of Microsoft 365 Division
 
Before Letsignit with our old signatures, we couldn't add banners or do anything else. Everything was complicated. Although some things were possible, it took a lot of time for IT to create all the signatures.

Letsignit makes it easy to create campaigns and manage contact groups. Its link with Office 365 simplifies internal implementation and allows for tracking of user usage. The separation of signature and campaign creation enables fast updates, even with multiple entities.

Frequently asked questions

1

How does Letsignit enforce PowerPoint templates across an organization?

Letsignit Slides applies your approved PowerPoint theme automatically when an employee opens the app — through a native Microsoft 365 add-in. No SharePoint sync, no manual opt-in. Themes are assigned per user, team, or business unit via Azure AD synchronization. Brand governance is enforced at the application level, not relied on employee behavior.

2

Is Letsignit Slides compatible with Microsoft 365 and Microsoft 365 Copilot?

Yes. Letsignit Slides is distributed via Microsoft AppSource, works natively inside PowerPoint (Windows, Mac, online), and is co-developed with Microsoft engineering. It integrates seamlessly with existing Microsoft 365 deployments, including Copilot-enabled tenants.

3

Can we manage multiple PowerPoint themes across business units or countries?

Yes. The admin console supports multi-theme, multi-BU, multi-country management from a single dashboard. Themes are assigned automatically based on Azure AD attributes (department, location, role). Each employee receives the appropriate theme without any manual action from Brand or IT teams.

4

How long does it take to deploy Letsignit Slides?

Deployment timeline aligns with Letsignit Signatures : a matter of days, not months. Because the add-in distributes via Microsoft AppSource and syncs with your existing Azure AD, there's no infrastructure project, no SMTP setup, no new vendor review.

5

Does Letsignit access the content of our presentations?

No. The Letsignit Slides Add-in distributes templates and brand assets to employees — it does not read, store, or access any content employees create inside their presentations. Presentations remain under Microsoft 365 control. The integration is client-side by design : no personal data or confidential content transits through Letsignit servers.

7

Can we update a template once and have it propagate everywhere?

Yes. Rebrands deploy in minutes, not months. Publish the new theme in the Letsignit admin console, deprecate the old one, and the change propagates automatically to every employee on their next PowerPoint open. No manual rollout, no communication campaign, no IT ticket.

8

What security certifications does Letsignit Presentations have?

Letsignit is dual-certified ISO 27001 and ISO 27018, with continuous audits, 100% EU hosting, and zero compliance incidents in 13 years. Security posture is identical across all Letsignit platform modules — Signatures, Presentations, and vCards.
