From Cortana to Copilot: technological foundations, progress and potential
Microsoft Copilot represents a significant development in the field of artificial intelligence and has developed into a central element in the Microsoft ecosystem since its introduction. Copilot 2023 was introduced as the primary replacement for the Cortana service set as a generative AI chatbot based on the GPT 4 series of large language models. The service supports users in numerous tasks in various Microsoft applications and offers personalized help through context-related AI functions. In this comprehensive analysis, the history, technical basics, integrations and future prospects of Microsoft Copilot are examined in detail.
Suitable for:
The origin and evolution of Microsoft Copilot
Microsoft Copilot was originally introduced in February 2023 under the name “Bing Chat” as an integrated function for Microsoft Bing and Microsoft Edge. In the course of 2023 Microsoft unified the “Copilot” brand over various chatbot products, which consolidated the “Copilot” analogy. At the Build 2023 conference, the company announced plans to integrate Copilot into Windows 11 in order to enable users direct access via the taskbar. Another important milestone was reached in January 2024 when Microsoft announced a dedicated copilot button for Windows keyboards.
The concept name “Copilot” itself has a deeper meaning. According to Microsoft CEO Satya Nadella, this term describes a software system that does tasks in interaction with a user. This is in contrast to “autopilot” systems that perform tasks without a user interaction. This distinction illustrates Microsoft's vision of a technology that supports and works with them instead of replacing them.
The introduction of Microsoft 365 Copilot on March 16, 2023 marked another important step in the development of the service. This AI assistant, especially for Microsoft 365 applications and services, was initially made available for a small group of companies and individuals for test purposes. At the announcement of the discontinuation of the independent Cortana app on June 2, 2023, Microsoft Bing Chat, Microsoft 365 Copilot and Windows Copilot presented the main alternatives to Cortana and thus underlined the strategic importance of Copilot for the company.
Technical foundations and architecture
Microsoft Copilot uses the Microsoft Prometheus model, which is based on Openais GPT-4-based model and further refined with the help of monitored and reinforcing learning. Copilot's conversation style is similar to that of Chatgpt, but offers additional functions such as quoting sources, creating poems, generating songs and using numerous languages and dialects.
Copilot currently uses various large voice models (LLMS), including Openais GPT-4O and a proprietary Microsoft model that enable the service. Copilot mainly uses graphics processors (GPUS) for training, while for the inference-the process of generation original editions from a AI model-both main processors (CPUs) and GPUs are used.
Microsoft specifically designed Copilot from the new computing power of the latest Intel and AMD processors. The latest generation of CPUs of these manufacturers contains Neural Processing Units (NPUS), which act as AI accelerator. Copilot uses the NPU to relieve work from the CPU and GPU and carry out inference on PCs, which are lacking powerful GPUs. The Microsoft Copilot+ PC program enables customers to track down which PCs can run complex AI workloads locally on the device.
A central element for Microsoft 365 Copilot is integration with Microsoft Graph, which contains information about users, your activities and the organizational data to which you can access. The Microsoft Graph API brings a personalized context to the request, such as information from emails, chats, documents and meetings of a user. This enables Copilot to provide context -related and personalized answers that are tailored to the specific needs and the work context of the user.
In addition, Microsoft 365 Copilot uses a semantic index that improves search relevance and accuracy by using a progressive lexical and semantic understanding of Microsoft Graph data. This leads to contextual more precise information calls, while security, compliance and data protection are preserved at the same time.

The different versions of Microsoft Copilot
Microsoft offers various versions of Copilot that are tailored to different user groups and applications. These versions differ in their range of functions and their target group, but all offer the basic AI support that characterizes the copilot.
The basic version, simply referred to as Microsoft Copilot, is a lightweight and free edition that is available for everyone that uses Windows, Microsoft Edge or the Bing website. It is suitable for general users and small companies who are looking for general AI assistance support instead of needing a significant workflow integration.
Microsoft Copilot Pro offers more demanding users. This version is aimed at Power user and offers priority access to all latest AI models from Copilot during peak times with faster response times compared to the free version. It also includes the image Creator from Designer - formerly known as Bing Image Creator.
Microsoft 365 Copilot is available as an add-on for office applications for companies. Microsoft 365 Copilot is a AI-supported tool that helps with work tasks. Users enter an inquiry in Copilot, and Copilot answers with AI-generated information in real time, which can include both internet-based content and work content, to which users have access authorization.
Since September 2023, Copilot has also been integrated into Windows 11, where he acts as a central AI assistant and can control several functions of the computer, such as settings. This underlines Microsoft's endeavor to seamlessly integrate AI support into the operating system and make it accessible to all users.
Microsoft Copilot Studio offers for those who want to create their own AI solutions. This is a graphic low code tool for creating an agent-including automation with Power Automats-and to expand a Microsoft 365 copilot with its own company data and scenarios. This flexibility enables companies to develop tailor-made AI solutions that are tailored to their specific needs.
Copilot in Microsoft 365: Integration and functionality
Microsoft 365 Copilot is integrated into the Microsoft 365 ecosystem in two ways. In addition to the user, it works to be embedded in the daily Microsoft 365 apps such as Word, Excel, PowerPoint, Outlook, teams and more to unleash creativity, develop productivity and improve skills. In addition, Microsoft offers a completely new experience called Business Chat, which works via the LLM, the Microsoft 365 apps and the data of the user-calendars, emails, chats, documents, meetings and contacts-to do things that were not previously possible.
In Microsoft Word, Copilot supports users in creating, understanding and editing documents. It helps to start the creative process, so that users never have to start again with an empty sheet. Copilot delivers a first draft to edit and iterate, which saves hours when writing, researching and editing. The user always keeps control as an author, drives his unique ideas forward and can instruct Copilot to shorten the text, to rewrite or give feedback.
For Excel, Copilot offers support in data analysis and visualization. It can suggest formulas, recommend diagram types and provide knowledge about data in spreadsheet. Copilot can help users with data analysis by formatting data, creating graphics, generating pivot tables, identifying trends and summarizing information.
In PowerPoint, Copilot users help to create presentations with a simple request and add relevant content from existing documents. It can also adapt text formatting, animation timing as well as presentation style and length based on user requests. These functions save time and make it possible to concentrate on the content and message of their presentations instead of dealing with formatting details.
For Outlook users, Copilot offers the option of designing emails with different lengths and tonality based on user inputs. Relevant information from other emails can use to create these emails. In addition, Copilot can summarize content from email threads, including the positions of the people involved and questions asked that have not yet been answered.
In Microsoft Teams, Copilot can present information for upcoming meetings, transcribe meetings and provide briefings when a user comes to a meeting too late. After a meeting, Copilot can also summarize discussion points, list important actions that were discussed in the meeting, and answer questions that were treated in the meeting. These functions improve the efficiency of meetings and ensure that all participants are up to date, even if they could not follow the entire meeting.
Latest developments and improvements
Microsoft continuously develops Copilot and regularly adds new functions and improvements. In January 2025, several significant updates for Microsoft 365 Copilot were introduced, which further improve the functionality and user -friendliness of the service.
One of the new functions is the Copilot promptly Gallery app, which helps users discover, save and share their favorite questions. This app offers a collection of sample questions that users can use as a starting point for their interactions with Copilot, which is particularly helpful for new users who may not be sure how to best interact with the AI assistant.
For Excel users, a new entry point for Copilot was introduced, which facilitates access to the AI functions and enables users to use Copilot's support in data analysis and visualization more efficiently.
In Outlook, new functions have been added that enable users to refine and improve their emails with the help of Copilot. These improvements help to make communication more clearly and more effectively and to reduce the time required to write emails.
PowerPoint received extended functions for creating and summarizing presentations with copilot. These improvements enable users to create high -quality presentations faster and to revise and adapt existing presentations more effectively.
A particularly remarkable improvement for Word users is the option of starting a chat with a copilot with a selected text in a Word document, whereby Copilot's answer is limited to the selection. This function enables more precise and context -related support in working with specific sections of a document.
In addition, Copilot Chat now offers personalized suggestions for questions based on the context and the previous interactions of the user. This function makes interaction with copilot more intuitive and helps users to exploit the full performance of the AI assistant.
Suitable for:
Industry and role-specific copilot solutions
Microsoft also extends the copilot portfolio with industry-specific and role-based solutions that are tailored to the special requirements of certain professional groups and industry. An example of this is Microsoft 365 Copilot for sales, a role-based copilot agent solution especially for sales employees.
Microsoft 365 Copilot for sales combines the performance of Microsoft 365 Copilot with seller -specific knowledge and automated sales processes. It helps sales employees to save time, to work more efficiently, to concentrate on the most important activities, to generate innovative ideas, to build stronger customer relationships and ultimately complete more business.
For the first publication cycle 2025, which runs from April to September 2025, Microsoft plans several new functions for Microsoft 365 Copilot for sales. These include support in prioritization of sales opportunities, automation of CRM data set-up updates, improved AI functions such as the provision of extensive CRM context in e-mail summary and supportive improvements for sales employees before, during and after meetings.
These industry-specific solutions clarify Microsoft's effort to make Copilot an indispensable tool for various professional groups by adapting the AI assistant to the specific challenges and workflows of different roles.
Administrative functions and IT administration
For IT administrators, Microsoft offers various functions for managing and monitoring Copilot in their organization. A central component is Copilot in the Microsoft 365 Admin Center, which transforms the IT admin experience by using AI to optimize routine tasks, generate knowledge that enables better decisions and to simplify finding the required configurations.
Organizations that have acquired Microsoft 365 Copilot licenses for their client can benefit from functions such as personalized summaries of trends and findings in important administrative areas based on their role and message center summary. The message center sumarization feature enables administrators to simply call up a summary of message center contributions across apps and services based on their client configuration.
IT administrators can also understand usage trends with Copilot Analytics to get insights into the use of Copilot in their organization. These analysis functions help to evaluate the value and effects of copilot and to identify areas in which additional training or adjustments could be required.
For organizations that want to prepare your data and systems for Copilot, Microsoft offers various services and functions that are available with Microsoft 365 licenses. This includes Sharepoint Advanced Management (SAM), which can help reduce excessive parts and clean up inactive websites, which cleans up Copilot data sources and improves the quality of the answers.
Restricted SharePoint Search (RSS) gives administrators time to check and configure the correct permissions for your SharePoint sites. You can add the checked and corrected sites to a permitted list that copilot can access.
Microsoft PurView can classify and mark data based on the sensitivity of the content. It can also prevent unauthorized parties or leaks and check copilot requests and answers. These security and compliance functions are crucial for companies that have to ensure that their data is protected while using the advantages of AI support at the same time.
Microsoft Agents: Transformative automation in everyday business
The development of Microsoft Copilot is progressing quickly and the potential for future applications and improvements is enormous. Microsoft continuously works to expand Copilot's skills and add new integrations and functions that make the service even more valuable for users and companies.
One area with great potential is the further development of Microsoft Agents, which are limited or focused versions of Microsoft 365 Copilot and act as AI assistant that can automate business processes. For example, an agent can be created that creates Helpdesk tickets, or a personnel agent who hides employee information from a data source. These agents can help automate routine tasks and enable employees to focus on more creative and strategic aspects of their work.
The integration of Copilot into other Microsoft products and services is another probable area of development. The more copilot is integrated into the entire Microsoft ecosystem, the more seamless and more valuable the AI support for users will be.
Improvements in the underlying AI models will probably also lead to more efficient and more precise copilot functions. Since the voice models are further developed and Microsoft improves its own proprietary models, Copilot will be able to do more complex tasks and offer even more nuanced and context -related support.
Microsoft also emphasizes the importance of data security and data protection when using Copilot. Microsoft 365 Copilot only uses the data to which users have access rights and respects the security, compliance and data protection guidelines of the organization. This obligation to protect data protection and data security will probably remain a central element of the future development of Copilot, especially in view of the increasing concerns about AI ethics and data protection.
AI in everyday life: What Microsoft Copilot means for companies
Microsoft Copilot is a significant progress in the use of artificial intelligence to support users in their daily work. By integrating into a variety of microsoft products and services and adapting to different user roles and requirements, Copilot has the potential that we work fundamentally.
The development of Copilot from a simple chat bot to a comprehensive AI assistant, which is integrated into the entire Microsoft ecosystem, shows Microsoft's commitment to the use of AI to improve productivity and creativity. With continuous improvements and extensions, Copilot will probably become an increasingly important tool for individuals and companies who want to use the advantages of AI support.
While Microsoft Copilot is being further developed, it will be interesting to observe how the service changes work processes, opens up new possibilities and further moves the limits of what is possible with AI support. The vision of a “copilot”-a AI assistant who works with the user instead of replacing him-could prove to be a transformative concept for the future of work.
