A language model only knows what it saw during training. Ask it about today's weather or this morning's news and it may guess.
One IA plugins fix that. When a question needs live data, One IA quietly checks the weather, the news, a web page or a GitHub project, then answers with what it found.
Notion works with your own account: connect it once from the Plugins page, then ask One IA to search, read or create your pages.
