Brian is your access to top generative AI solutions

– Understanding the capabilities and limitations of the top technologies out there –

OpenAI’s GPT technology

Brian connects his users with selected top technologies available. Basically, generative AI systems allow the users to generate new content. In this section we do very much focus on the text generation. Here you learn more about the technology and how it is used to power Brian – our secure, multifunctional digital assistant for consultants and business professionals.

First, some basic explanations:
– ChatGPT is a chat-based software powered by OpenAI’s GPT technology
– GPT or ‘Generative Pre-Trained Transformer’ is the name of an AI model series powering ChatGPT
– GPT 3.5 is (as of March 2023) the latest version of the AI model powering ChatGPT as well as some of Brian’s skills too
– OpenAI is the company (by 49% controlled by Microsoft) developing AI models and solutions such as GPT, Dall-E, Codex and more

The capabilities:
– Contextual understanding of text
– Generation of texts on wide range of topics
– Trained on the knowledge of the internet and millions of books
– Thanks to 175 billion of parameters, one of the most powerful generative AI models out there

The limitations
Before using the GPT-powered skills of Brian, we want to ensure that you are aware of the current limitations of this technology:
– GPT answers are not necessarily factually correct, so we strongly advise you to double-check them
– GPT answers are not necessarily up to date since the training data ends as of 2021
– GPT runs on Microsoft servers in the USA, so we strongly advise users not to include any personal data in the request text

Brian’s GPT integration
When using GPT capabilities via Brian:
– We don’t share the user’s identity with OpenAI/GPT – AskBrian stands in between. We forward the request text only
– We use paid GPT APIs for better availability, we do not use ChatGPT
– We don’t share any files with OpenAI’s GPT, even if users should provide any
– OpenAI is not a subprocessor of AskBrian as defined by GDPR because the processing of personal data is not intended
– Users who provide consent for the GPT skills also accept the Privacy Policy and Terms of OpenAI, which can be found at

User’s GPT consent
Before using the GPT-powered skills of Brian for the first time, users must provide one-time consent via the regular Brian interaction channels via email, teams or slack:

“I want to experience the GPT skills. I understand that the answers might not be factually correct or actual. I will not include personal data in my requests because of processing in the USA. I accept the disclaimer at”

GPT consent reversal
Users can withdraw their GPT consent by sending a request to It is sufficient to write something like “I want to withdraw my GPT consent.”

GPT powers ‘Next Level’ skills of Brian and functions after user consent as a fallback source of answers for requests for which Brian was not trained yet.

The GPT-powered skills (as of March 2023) are:
– Draft bullets
– Brainstorm
– Formulate
– Ask Anything
– Definitions

About the fallback
If a user asks a question and our NLP is less than 70% sure Brian can respond it (that it is a pre-trained skill of Brian) the fallback scenario is triggered. In this scenario the request text (without user identity and without any shared attachments) is forwarded to OpenAI’s GPT and answered by it.

Note on handling of emails
First the email body is analysed by our NLP and then the subject line. If in both cases our NLP does not recognize a pre-trained skill, the subject line text is used as user query forwarded to GPT. If the subject line includes no text, the email body text (excl. signature etc) is used as user query. It is therefore the best to leave the subject line of your emails to Brian blank.

Finally, we would like to elaborate on the differences between ChatGPT and Brian. We would also like to explain what are the differences between using GPT via Brian vs. using ChatGPT directly.

Brian’s capabilities ChatGPT hasn’t
– Brian is a multifunctional digital assistant connected with multiple digital services and data sources being able to provide actual and factual information too
– Brian communicates via Email, Teams and Slack
– Brian can process documents and create new documents combining multiple technologies in one solution
– Brian addresses specific use cases with specific settings and provides more target audience-optimized outputs
– Brian is independent – we are not dependent on Microsoft, Google or any other technology

Advantages of using GPT via Brian
1. Security: AskBrian stands between the user and OpenAI, the user remains unknown for OpenAI
2. Specificity: We use fine-tuned GPT model for use cases of knowledge workers
3. Availability: Brian uses the paid OpenAI APIs having less downtimes than the free ChatGPT service
4. Integrations: Brian combines multiple technologies to deliver his answers – e.g. bullets are delivered together with high quality pictures
5. Independence: Should we find a better technology for individual use cases, we will switch. We consider especially the quality of service, data privacy and the price

Advantages of using ChatGPT directly (not via Brian)
1. ChatGPT is free (as of now)
2. ChatGPT allows longer input texts (Brian’s limit at 256 characters of input text)
3. ChatGPT communicates in any language, Brian in English, German, French and Japanese
4. ChatGPT provides code, Brian is not optimized for this
5. ChatGPT understands follow up questions – Brian is not working with context as of now
