The Opus 2 AI assists feature includes Canvases, which allows you to pre-analyze any document or groups documents.
Performing an AI analysis on a document can sometimes take a little time. If you have a large number of documents that you want to analyze, putting them in a canvas will automatically perform an AI analysis on those documents so that when you access them at a different point in time you do not need to wait for the analysis to take place.
When you put a group of documents into a canvas, an orange semi-circle will indicate that the documents are being analyzed. A green circle with a tick indicates that all the documents in that canvas are ready.
You can create a new canvas by clicking on the
symbol and providing a name and optional color for the canvas.
To add documents to your canvas, simply use the tic boxes to select the relevant documents from your folders then click and drag the 
icon to the desired canvas.
You can also click the Actions dropdown and select 'Add to canvas'
**Please note that you do not need to add a document to a canvas in order to perform an AI analysis.**
The AI assist tool can still be accessed directly from any document in your project. The canvas feature simply allows you to put larger sets of documents through an analysis in advance of when you want to access them.
