Sitefinity 15.3: AI-Powered CMS for Smart Marketers and Agile Developers

It’s 7:45 a.m. Your laptop screen casts a pale glow as you sip coffee and glance at your calendar. It’s one of those days—back-to-back meetings, urgent content deadlines and little breathing room. You open your project management tool and reshuffle priorities again.

Today’s to-do list? Two blog posts, a press release draft, a few web copy updates and syncs with CRO, SEO, UX, Design and Front-end teams to prep new campaign pages.

Business as Usual?

No matter how sharp your plan, potholes in the day—unclear requests, missing assets, last-minute changes—can knock you off course. And before you know it, you're juggling Teams chats, support tickets, inbox noise and reminders in OneNote. Multiply that by hundreds of content updates and dozens of projects each month and it’s easy to see why task queues pile up fast.

Welcome to the Marketer’s Reality.

Today’s digital-first buyer expects speed, relevance and a personalized experience. That means we’re not just producing content—we’re orchestrating channels, data, design and delivery. To keep up, we need tools that actually work with us. Tools that help us:

• Streamline content ops
• Accelerate execution
• Make faster, smarter decisions
• Scale across channels without burning out

So, What’s New in Sitefinity 15.3?

As someone who both markets and uses Progress® Sitefinity® CMS, I’m genuinely excited about what’s inside. These enhancements are practical, focused and built for real-world teams.

Here’s My Top 3

1. Get More from AI—Without the Guesswork

We all know GenAI can kickstart creativity and cut down on grunt work. But what about safety? Governance? Integration?

Introducing: Sitefinity Packaged AI Service

This new Sitefinity Cloud Add-on helps you start using GenAI in Sitefinity right away—no complex setup, no legal bottlenecks, enabling you to quickly rollout GenAI support in an environment you already love, define the scope of use and control cost without limiting creativity.

Sitefinity Packaged AI Service is all about quick wins built into your CMS. No more tab-switching or staring at blank screens.

You get a pre-configured integration with a top-tier LLM plus options to customize usage based on your brand, voice and compliance needs.

Sitefinity 15.3 brings powerful AI CMS capabilities closer to your workflow with tools that help you:

• Jumpstart content creation
• Summarize, optimize and improve content
• Define powerful actions without writing complex prompts
• Auto-suggest taxonomy to tag content faster

As a marketer, that means I can rewrite or refine content with a single click—no prompts, no guessing. As an org, it means you're still in control.

2. AI-Powered Image Search

I am a huge fan of Marie Kondo but I have come to realize that asset chaos is real. Even with a Digital Asset Management (DAM) integration deployed organization-wide, things slip through the cracks—banners, hero images, one-off graphics. The good news is that, even when best practices for naming and organizing images get overlooked, AI can help save the day.

3. Copy Section Presets Across Sites

Section presets are a hidden gem. They let you save and reuse page layouts so you’re not rebuilding the same components over and over.

Now in 15.3, you can copy those presets across sites, not just pages. That’s huge—especially if you manage multiple brands, regions or business units or simply need to spin up a localized landing page between meetings.

It’s faster, more consistent and friendlier for devs and marketers alike. No need to fiddle with code, take notes on margins, paddings, font-sizes and CSS classes or understand how layout grids work.
You can now build or enhance a landing page in minutes and give it a fresh makeover with a section layout you know will boost KPIs up.

Why I Keep Coming Back to Sitefinity

Sitefinity keeps growing on me. It’s been ten years since I first tried it and I’m still surprised by how much power is packed under the hood.

Version 15.3 brings meaningful upgrades that make everyday work easier and more efficient—plenty of reasons to consider making the switch or upgrading. Need to plan an upgrade? Our partners and Professional Services team can help.

Thanks for reading. I can now mark this as “completed” and get on a quick call with Jon to brainstorm on what to demo during the upcoming release webinar.
