In this guide, you will find instructions about artificial intelligence (AI).

(info) Eesti keeles



Artificial intelligence or AI (in Estonian Tehisaru or TI or Tehisintellekt) can be used across all university activities: teaching, research and development, as well as support services. Artificial intelligence has a wide range of applications. 

  • ChatGPT Education is an AI tool developed by OpenAI that enables the use of ChatGPT language models and various tools through a user-friendly interface.

  • Azure OpenAI API is an important product that allows technical users to access the powerful AI models developed by OpenAI. This API allows developers to build apps that can generate human-like text, translate languages, answer questions, write articles, and more.
  • GitHub Copilot is an AI-powered programming assistance app that provides real-time suggestions and solutions as you write code. Employees, lecturers and students of the University of Tartu can use Copilot to improve their coding process and speed up development work and research projects.
  • Virtual assistant (Tiksu) is an artificial intelligence-based chatbot that is trained to answer questions based on this wiki.
  • Microsoft 365 Copilot is a tool designed to streamline and simplify employees' daily tasks within the Microsoft 365 application ecosystem, including Word, Excel, PowerPoint, Outlook, and more. Unlike standard Copilot (copilot.microsoft.com), Copilot 365 allows you to use Copilot directly in Microsoft applications. With it, for example, you can transcribe Teams meetings, write e-mails in Outlook, and perform data analysis in Excel without leaving the application. 
  • Microsoft 365 Copilot Chat is an AI-based chatbot developed by Microsoft that allows using ChatGPT language models through a convenient user interface. It uses sophisticated algorithms and machine learning models to understand user queries and provide relevant responses. Futhermore, DALL-E 3, the latest and most capable text-to-image model from OpenAI, is generally available to everyone within Bing Chat Enterprise.
  • SharePoint agents can answer questions about the content on any SharePoint site or document library that the asker has permissions with. If you have edit permissions on a SharePoint site, you can even create agents for specific tasks and share them with your team.
