How AI Builder Is Democratizing AI with Custom Prompts

AI used to feel like something reserved for data scientists and developers. You needed models, training data, and a whole lot of math. But with the latest updates to AI Builder in Microsoft Power Platform, that’s changing fast. Now, anyone can build intelligent, context-aware solutions using natural language, and it all starts with prompts.

In the 2025 Release Wave 2, Microsoft is turning AI Builder into a full-fledged prompt engineering platform. Whether you’re generating text, summarizing documents, or building custom GPT-powered chatbots, prompts are now the key to unlocking AI’s potential in low-code environments.

Let’s explore what’s new, what’s exciting, and how you can start building smarter with prompts.

Prompts as First-Class Objects

The biggest shift is that prompts are now first-class objects in AI Builder. That means you can create, edit, manage, and reuse prompts just like you would with flows or apps.

You’re no longer limited to prebuilt models or rigid templates. Instead, you can write your own prompts like “Summarize this document in a friendly tone,” or “Generate a follow-up email based on this customer interaction,” and use them across your Power Platform solutions.

Prompts can be grounded in Dataverse data, connected to external sources, and even enhanced with Power Fx logic. It’s flexible, powerful, and surprisingly easy to use.

Power Fx Meets Prompt Engineering

One of the coolest additions is the ability to use Power Fx inside prompts. This lets you add dynamic logic to your AI instructions.

For example:

• Format dates or currency values before passing them to the prompt
• Add conditional logic (“If status is ‘urgent’, use a more serious tone”)
• Pull in related records or metadata to enrich the prompt context

This turns your prompts into intelligent, responsive components that adapt to the data they’re working with. And because it’s all low-code, you don’t need to be a developer to make it work.

Prompt Fragments

If you’ve ever written a prompt and thought, “I wish I could reuse this tone or structure,” you’re in luck. AI Builder now supports prompt fragments, which are reusable snippets that you can plug into different prompts.

Think of them like building blocks. You might create a fragment for:

• A formal closing paragraph
• A friendly greeting
• A structured summary format

Then, you can mix and match fragments to build new prompts faster and with more consistency. It’s a great way to maintain brand voice, tone, and formatting across your organization.

Copilot as Your Prompt Coach

Writing good prompts is part art, part science. That’s why Microsoft is bringing Copilot into the prompt authoring experience.

Copilot can:

• Suggest improvements to your prompt wording
• Explain what a prompt is doing and why
• Help you test and refine outputs
• Recommend fragments or formatting options

It’s like having a writing coach and a data analyst rolled into one. Whether you’re new to prompt engineering or just want to level up your skills, Copilot makes the process smoother and more intuitive.

Versioning and Prompt Management

As prompts become more central to your solutions, managing them becomes important. AI Builder now includes version control for prompts, so you can:

• Track changes over time
• Compare performance across versions
• Roll back to previous versions if needed

This is especially helpful in enterprise environments where prompts may need to be audited, approved, or optimized over time. It also supports collaboration so multiple makers can work on prompts without stepping on each other’s toes.

Getting Started with Prompts

If you’re ready to dive in, here’s what I recommend:

• Open AI Builder and explore the prompt authoring interface
• Start with a simple task like summarizing a record or generating a message
• Use Power Fx to add dynamic logic
• Create a few prompt fragments for tone, structure, or formatting
• Ask Copilot to help refine and test your prompts
• Track performance and iterate using version control

And don’t be afraid to experiment. Prompt engineering is a creative process, and the more you play with it, the better your results will be.

Final Thoughts

With these updates, AI Builder is becoming a true democratizer of AI. You don’t need a PhD or a Python script. You just need a clear idea and a well-crafted prompt.

Whether you’re building apps, automating workflows, or enhancing customer experiences, prompts give you a new way to think, create, and innovate. And with Copilot by your side, you’re never building alone.
