From standalone tools to a single intelligent interface

A year and a half ago, the Copilot portfolio was fragmented. There was Microsoft 365 Copilot for office work, GitHub Copilot for developers, Copilot in Windows for everyday users, and Copilot Studio for building custom agents. Each lived in its own application, with its own login and different behavior.

Now Microsoft is bringing all these tools together. According to an official post on the Microsoft 365 blog from May 28, 2026, the Copilot application has undergone a complete redesign. It is no longer just a chat window — it is a unified workspace with navigation, conversation history, agents, and a model switcher.

"We're moving from individual features to connected experiences. From adding capabilities to shaping outcomes. From expecting people to adapt to technology, to technology that adapts to people," wrote Jon Friedman, Chief Design Officer at Microsoft.

Work IQ: The brain that understands your work

The key innovation is Work IQ technology — an intelligent layer that understands the context of your work across emails, files, chats, and meetings. It's not just about searching documents. Work IQ adapts the depth of response based on what you need at the moment: a quick reply to a simple query, or a deeper analysis across dozens of sources.

Thanks to this, Copilot handles complex enterprise scenarios — such as preparing for quarterly performance reviews or adapting to organizational changes. And what's significant for Czech companies: Work IQ also works with Czech-language documents and emails. Microsoft 365 Copilot supports Czech both in the user interface and in content processing.

Model switcher: GPT or Claude? You choose

In the new version of Copilot, Microsoft has integrated an AI model switcher. Users can choose directly in the interface whether they want a response from OpenAI (GPT) or Anthropic (Claude). This is a fundamental shift: Microsoft is moving away from relying exclusively on the OpenAI partnership and opening Copilot as a platform for multiple models.

For Czech users, this means flexibility. Claude excels in precise writing and analyzing long texts, while GPT is stronger in creative tasks and programming. You can choose the tool based on the task — without switching between applications.

Copilot Cowork: An agent that works while you sleep

In early May 2026, Microsoft launched Copilot Cowork — an agentic colleague that works asynchronously. You assign it a task (such as "prepare a market analysis for the Czech e-commerce sector") and Cowork works on it in the background. You don't need to keep your browser open or your computer turned on — the task runs in the cloud.

According to the official announcement by Charles Lamanna, Executive Vice President for Copilot and Agents, Cowork now also works on iOS and Android. You can assign a task on your way to work and find the result ready when you arrive at the office.

Cowork also comes with Skills — reusable instructions for standardized tasks such as document creation, meeting organization, or research. And with plugins that connect Cowork with external systems: Dynamics 365, Power BI, as well as third-party tools like LSEG, Miro, or monday.com.

GitHub Copilot: Coding as conversation

The developer part of the ecosystem is not falling behind. GitHub Copilot has surpassed 150 million developers on the GitHub platform, and according to Satya Nadella from the January investor call (Fortune), it recorded over a million registrations during the first week after launching the new version.

GitHub Copilot is increasingly integrating into the broader Copilot ecosystem. A developer can discuss solution architecture in Copilot Chat and immediately switch to code generation — without leaving a single application. For Czech developers and companies, it is available for $10 per month (individual plan), $19 (Business), or $39 (Enterprise).

What does the new design bring?

Microsoft also published concrete performance numbers for the new version:

• 50% faster loading of the application — crucial for daily use
• 10% faster response for complex prompts (measured at the 95th percentile)
• Usage increase of 27% in Word, 33% in Excel, 43% in PowerPoint, and 30% in Outlook after deploying the new interface
• Progressive rendering — Copilot starts with a clean response and adds structure, formatting, and recommended next steps as the task grows

Microsoft designers applied the progressive disclosure principle: the interface is initially minimalist and reveals additional options only when you need them. The left panel with agents, history, and conversations slides in and out depending on context.

Small businesses and Czech freelancers: Copilot as standard

From July 1, 2026, Microsoft is launching a new SKU: Microsoft 365 Business with integrated Copilot. Small businesses will no longer need to purchase Copilot as a separate add-on — it will become part of the standard subscription. This is also crucial for Czech freelancers and smaller companies, for whom the previous price of $30 per user per month (approx. 700 CZK) on top of the M365 subscription was often a barrier.

The new offering includes over 1,000 connectors to applications like Shopify, PayPal, Xero, DocuSign, Asana, or Canva. Copilot can thus automate tasks across systems — without having to switch between applications.

Growth that speaks for itself

The numbers from Microsoft's latest fiscal report show that the bet on AI is not just marketing:

• AI business surpassed $13 billion in annual revenue (175% year-over-year growth)
• Azure AI grew by 157%
• M365 Copilot saw a 10x increase in license count over 18 months among customers who deployed it first
• 160,000 organizations used Copilot Studio and created over 400,000 custom agents within three months
• Daily active Copilot users doubled quarter-over-quarter, with usage intensity up 60%

Availability in Czechia

Microsoft 365 Copilot is fully available in Czechia through Microsoft's standard licensing programs. Czech is supported for both the user interface and for document and email processing. Copilot Chat remains free for all users with a Microsoft account.

GitHub Copilot can be subscribed to directly through GitHub and used in any development environment including VS Code, JetBrains, or Neovim. Copilot Studio is available for companies that want to build their own agents — including voice agents that understand Czech.

Regarding EU regulation: Microsoft has committed to meeting the requirements of the EU AI Act, which came into effect in 2025. Enterprise customers have access to data management, audit, and access control tools, including Microsoft Purview, which according to Microsoft audits over 2 billion Copilot interactions.

What does this mean for the everyday user?

For Czech users — whether developers, marketers, accountants, or students — Copilot is becoming the single place for interacting with AI. You no longer need to jump between ChatGPT, Claude, and GitHub Copilot. Everything is in one application that knows the context of your work.

For businesses, it means simpler management: one tool, one license (from July 2026), unified security policies. And most importantly — AI that understands your business, not just the public internet.
