Danish Language Council: Big differences in chatbots' answers about Danish

The Danish Language Council (Dansk Sprognævn) has examined how good different chatbots are at giving advice on linguistic correctness in Danish. This is stated in the council's own announcement about the new issue of its member magazine Nyt fra Sprognævnet (2026/3, October 2026).

The study was carried out by three council employees and covered six chatbots. A chatbot is a program you can type with, and which answers questions in everyday language.

Five topics in the test

The chatbots were tested with questions in five areas:

- punctuation, such as commas and periods - orthography, meaning how words are spelled - morphology, which covers inflection and word formation - syntax - morphosyntax

Big differences

The council concludes that there are large differences in how well the individual chatbots give correct and thorough answers about linguistic correctness.

The results are described in the article "Jagten på den gode og sikre chatbot" (The hunt for the good and reliable chatbot). It deals with whether chatbots can be trusted when you seek language advice.

What is not stated

The council's short summary does not say which six chatbots were tested, which specific questions they were given, or how the individual chatbots performed. Nor does it state how the test was carried out in detail.

The study was conducted by the council's own employees and has not been independently assessed. It is also not stated that anyone else has covered it.
