About

Pillar is the SDK for building AI agents into your product.

Problem

Businesses had too much information spread across their documents, help centers, and internal tools. Users spent too much time looking for information and completing simple tasks across different pages.

Approach

Designed an AI assistant that combines search, answers, and actions into one simple experience with a clean and intuitive interface.

My work was devided into two parts—Branding and Product.

Starting point

Before designing the product, we established the foundation that would guide every decision moving forward.

To establish a strong foundation, I defined the brand direction, created the visual identity and developed the core design principles that ensured consistency across the entire experience.

While the engineering team focused on building the product, I led the design effort and created the core design foundations that shaped the product from day one.

Marketing website

The initial designs were created in Figma. To move faster and avoid taking up engineering time during the validation phase, I built the entire website in Cursor, allowing us to test the idea much sooner.

Product

I worked on the product, branding, and website simultaneously.

The main goal was to create an intuitive product flow while ensuring the product remained visually consistent with the marketing website and overall brand identity.

AI assistant

Because the AI assistant was the heart of the product, I explored different customization options, allowing users to configure its appearance and behavior directly from the dashboard settings.

Main tool
Cursor

Pillar was built using Cursor and a vibe coding workflow, with Figma AI helping accelerate the design process. This allowed me to iterate, refine, and ship updates on the fly without relying on engineering help.
