Design and Artificial Intelligence (AI)

With tools becoming easier to access, AI is opening up lots of new and exciting creative possibilities.
And with this progress, an important question comes up:


How can AI
boost creativity without compromising originality?

In a context where the widespread use of artificial intelligence tends to produce standardised and predictable results, the role of the designer becomes the true differentiating factor. Mastering the available tools is not enough — it is essential to apply them with aesthetic sensitivity, critical insight, and an understanding of the human context. It is this combination that turns AI into a powerful ally of creativity. Designers can use AI as a strategic partner to streamline repetitive tasks, explore creative variations, and analyse data more efficiently.

When used with purpose, technology enhances the capacity to innovate.

Artificial intelligence has come to enhance the role of the designer. When applied strategically — combining creativity with contextual understanding, critical thinking, and brand vision — AI enables us to innovate and deliver truly original and distinctive outcomes.

At Magnasubstância, we value and use these tools with intention and originality. By combining AI’s capabilities with our creative vision, we develop unique, relevant solutions with a strong identity. In our view, AI is a powerful ally — one that can lead to authentic solutions and added value for our clients.
