AI Tools

In this section, we offer a set of recommended Generative AI tools whose use can enhance our teaching. However, we remark that currently the University cannot offer any license for them, so we clarify whether they are available and/or free.

Please, be mindful that the tools shown here are not specific to uc3m, but general ones. Therefore, it is crucial to remember that they should be used with caution. You should never send or introduce any personal data, nor -according to European Union regulations- use them to detect behaviors or infer emotions (stress, detachment, exhaustion, frustration) of the students during the evaluation process. Then, most of the cases where AI systems are going to be applied for assessment purposes will likely be considered as high risk systems, requiring special caution and additional obligations. However, you can use them without restriction as an aid in case of exam preparation or in other of your non-assessment teaching environments. These tools are trained by interaction with the users, so you cannot guarantee the privacy of the data used, and eventually you may lose track of the information that you upload, as since that moment it becomes part of the tool's knowledge. The uc3m cannot guarantee, and is not responsible for, that these tools are designed and operate in full compliance with applicable rules and regulations, so their use must be especially cautious to minimize risks.
