Microsoft relaunches 365 Copilot with a design that loads 2x faster

Microsoft has launched a large-scale redesign of 365 Copilot, the interface for the assistant built into Office. According to the company, the new version loads 2x faster, and answers are now more structured and easier to read. This is not just a cosmetic update: it brings serious improvements in performance and usability.

What changed in the interface

The main innovation is a technique Microsoft calls "progressive disclosure". The idea is simple but effective: instead of showing every available tool and button at once, Copilot now analyzes your request and shows only the relevant options. This makes the interface less cluttered and makes it quicker to find your way around the features. Instead of a standard set of buttons, you see only what makes sense for your specific request.

Text formatting (bold, italic, headings) now works directly in the prompt field, so you don't need to hunt for buttons in a menu or switch to a separate window. The field expands on its own as you type more text, which makes work smoother and more natural. It is a small detail, but it improves the overall experience.

Why load speed matters

Doubling load speed sounds simple, but in practice it reduces friction. While you wait for Copilot's reply, your mind wanders: you lose focus and reflexively switch to another tab or app. A 2x speedup means the answer arrives before you develop the habit of switching away. Psychologically, that is a big improvement.

The update is rolling out simultaneously on desktop and mobile devices, so you will feel the speed gain everywhere: in Outlook, Word, Excel, PowerPoint and the other apps in the suite. For mobile users it matters especially: mobile internet is often slower, so a 2x speedup is very noticeable there.

Structured answers

Copilot now presents information in a more organized format. When you ask the assistant to summarize a document, draft an outline, work through data or generate content, the answer arrives not as a wall of text but with a clear structure:

• Clear headings and subheadings
• Bulleted lists and numbered items
• Logically separated content
• Proper use of whitespace for readability

This is especially useful when you need to scan information quickly. Instead of reading through a long paragraph, you see the structure at once and can find what you need in seconds. For office workers who process information constantly, this is a significant productivity gain.

What this means

Microsoft continues to invest in making Copilot not just a polished AI demo but a useful tool for real work. Fast loading + a convenient interface + structured answers = less friction in an office worker's everyday life. Each of these improvements may look minor, but together they add up to a noticeable gain in convenience and productivity.

The update is rolling out these days and should reach all Microsoft 365 users within the next few weeks.
