I’ve been waiting forever. At this state, I’m not sure if I should continue taking notes in Marginnote because I’m not even sure if this app will continue to be relevant in near future.
AI features were promised to be shipped in August and here we are in mid September without any meaningful updates.
We apologize for keeping you waiting for so long. However, AI is a brand-new exploration for us, and we are making small but steady progress every day—whether in terms of features, interactions, or bug fixes. We will be launching exciting AI functionalities that are fully adapted to MarginNote, rather than just simple integrations. This will undoubtedly take time to polish, but we are all striving for it.
If you wish to use AI in MarginNote right now, you are welcome to try the AI plugin. Thank you for your understanding and patience. 
Is there an English version to the AI extension?
yes we have
Please add a link to it or provide a name of it. I would appreciate it!
Click the download link to start downloading. Most of the content inside is in English, and you may use the API of your own GPT or other similar models
Can we get a tutorial on how to integrate this API to iPad version of MN4?
Do you mean the use of the plugin? For the API, you can use ChatGPT’s API (or rather, the API key—a string of numbers and characters) and copy it into the plugin.
Apologies for being a dumb newbie with AI.
Are you saying I can use AI features if MarginNote with a different AI service than what is built into MN4? That is, if I already pay for AI service elsewhere (ChatGPT, NotebookLM) I can connect the two?
Yes, this is based on the AI plugin linked in the previous message.
