About us

Gradr.ai is a service provided by Tribble AS. We are a software company in Oslo founded by former students at and with support from NTNU and organizations affiliated with the innovation environment at NTNU such as Spark* and Engage from C.E.E.

Our vision is that it should not be possible to pass off texts created by artificial intelligence as one's own original work.

Since we launched Gradr.ai in June 2023, thousands of teachers have adopted the service in their daily work, and the number of schools and teachers using the service is growing rapidly in Norway, Sweden, Denmark, and Finland.

Our core values are openness, honesty, and innovation.

We are proud that we contribute to more transparency and higher academic integrity in schools every day. We are also concerned that technological innovation should not come at the expense of privacy. Therefore, we always work with data security and privacy in focus, and do not use data from students and teachers to train our machine learning models.

We are working proactively to expand the functions we offer in Gradr.ai to help teachers in their teaching work, achieve better precision on our plagiarism tool, and expand to support more languages.
