u:ai – AI software

For:  students    employees

u:ai is an artificial intelligence platform specifically developed for the academic environment and part of the AI services of the ZID.

  • analyse documents and translate them into other languages

  • create chatbots with individually expanded knowledge bases


uai.univie.ac.at

  • Update

    New language models

    You can now select the following additional language models in u:ai:

    • Claude Opus 4.6
    • Gemini 2.5 Pro
    • GPT 5.2
    • Mistral Large 3 (data processing exclusively within the EU)

    The Image Generator module now uses the GPT Image 1.5 model with data processing within the EU.


    Chat export, search within chats

    New features in the Chatbot module allow you to export chats as a DOCX file or use full-text search to find content within your saved chats.

Using u:ai

Open u:ai via uai.univie.ac.at and login with your active u:account for employees. You can then use u:ai.

The AI software consists of several modules and the Tailored AI function.

Modules

User guide: Using modules

  • Chatbot: make text-based requests
  • Image Generator: create images
  • Translator: translate texts into more than 100 languages

Tailored AI

User guide: Using Tailored AI

With the help of Tailored AI, you can create a chatbot where you can expand the knowledge base with individual content from documents. With the basic instruction, you can further customise the responses to your needs. It is also possible to share your Tailored AI with other users.

Using u:ai via an API

u:ai API access is available to employees and students. It is suitable for scenarios where u:ai’s graphical user interface does not meet all the required specifications – for example, when u:ai needs to be integrated directly into your own scripts or applications. A solid understanding of IT is a requirement to use this service.

Students can obtain u:ai API access as part of courses or academic theses.

Further information: u:ai API access

Supported languages

Requests to u:ai can be made in more than 100 languages. Unless you specify otherwise in your request, the output language will be based on your input language.

Restrictions

Please note the following restrictions when using u:ai:

Data base

u:ai cannot answer university-specific questions, as the software has not been trained with university data.

Quality of answers

The answers and information generated by u:ai may contain errors or inaccuracies. Always verify the information provided by consulting additional sources.

You are responsible for the reflected use of the generated content.

Personal data

  • You can enter personal data in u:ai.
  • However, the principle of data minimisation applies: process as little personal information as possible.
  • Sensitive data must not be entered.

More Informationen: Data protection

Note

If you use the Internet Search or certain language models, there is no guarantee that your data will be processed within the EU. You will see a corresponding note before use. 

In such cases, do not enter any personal or confidential data.

Storage period

u:ai is not suitable for storing content permanently:

  • Saved chat histories are cleared 365 days after the last prompt.
  • For reasons of GDPR compliance, your u:ai account will be deleted if you do not log in to u:ai for 90 days. If you log back into u:ai later, your account will be recreated. Users who are administrators of a Tailored AI are exempt from the deletion period.

Credit

You have a monthly credit of 20.00 euros available in u:ai. These costs are covered centrally. If the monthly amount is used up, you will not be able to use u:ai until the following month.

You can find your current credit balance in u:ai in the top right-hand corner.

Use your credit sparingly. You may need it later for assignments or coursework in a course.

The costs for individual requests depend on the length of the request and the response. You can expect the following costs:

  • Short text request: around 0.01 euro
  • Large file upload or generated image: around 0.20 euros 

When Internet Search is activated, the costs may be higher depending on the web content analysed.

You can find detailed information on the costs of the individual models in the modules where you can select the language model, as well as in Tailored AI. To do this, open the language model settings and select Model Pricing.

Planned features in 2026

  • AI agents: Automate processes efficiently using AI
  • Improvements to file upload for Tailored AIs and Document Analyser: upload up to 500 documents, text recognition (Optical Character Recognition, OCR), read all spreadsheets in Excel documents
  • Transcribe audio or video files
