AI integration in Opti.Tax: what you need to know
In which tasks does the AI integration in Opti.Tax help me?
The AI integration in Opti.Tax is called the „AI Assistant“ and provides support with a wide range of tasks. Among other things, the AI uses keywords to generate complete texts, creates process chains from rough descriptions or voice recordings, checks process descriptions for potential risks, and formulates suggestions for appropriate control measures.
How exactly do I use this AI integration in Opti.Tax?
The AI features in the software have been deliberately designed to be incredibly easy to use. There is a button to open the chatbot, where you simply enter your enquiry. Alternatively, in many places you can use the context menu (right-click) to run specific AI functions, such as identifying relevant risks.
Which AI model is used in Opti.Tax?
The AI integration in Opti.Tax utilises ChatGPT from OpenAI, Inc. A valid API key is required to use this feature, which must be obtained directly from OpenAI in addition to Opti.Tax. Where required, hsp offers cost-effective support with both the booking and the set-up process.
Very easy to understand and use, so that everyone can benefit from AI.
The AI assistant now takes care of tedious and annoying tasks.

How AI takes the strain off professionals
Why integrated AI is more effective than a separate chat window
The key advantage lies in the context. The AI function is thus embedded within the technical structure of Opti.Tax. This means that users do not have to copy content between different applications. Instead, they can generate, evaluate and process suggestions directly in the correct location. This reduces discontinuities and improves traceability.
Use safely and responsibly
A separate OpenAI account or API key is required to use the service. In this regard, OpenAI, Inc. states that, by default, it does not use incoming or outgoing data from business customers or the API platform to train its AI models. Regardless of this, organisations should define their own data protection, authorisation and approval policies and should not publish unverified AI results.
