+### API settings
+Extra menus are available for each API you set (contextmenu: when you write click on the table or on an annotation in the pdf reader). For Bard and Open AI, you can set the models you want to use. You can set the maximum token used for OpenAI as well. \
+The plugin has simple default prompt for each action. You can set your own in "AI custom prompts". Remember that when you change them, the menus would mean something completely different from the label (If you change paraphrase prompt into something else for example). \
+Last, you can set the language for Google and DeepL translation the label of the contextmenu will change accordingly.
