ChatGPT has a new "Company knowledge" feature for Business, Enterprise & Edu. You connect company apps like Slack, Google Drive, and others. Then you can chat with it to get info drawn from those sources, like "where did we leave off on this project" or "when was the idea for this thing first floated"?

Here's the announcement with screenshots & here's the documentation. If you're eligible to use it you'll see a button when you start a new chat.
