I think this looks super duper promising, congratulations on the design and feel of the product. I do use a canvas tool and notion too, and I've been looking for something that combines them, but haven't found anything yet. I'd like to give some feedback that would make me more likely to use this. The biggest thing I was looking for in combining the two tools was to add canvases inside of pages, rather than pages inside canvases. Pages inside canvases doesn't seem that helpful to me, and also doesn't keep the hierarchical structure I like in Notion. The second thing is about how quickly I can add things on the canvas. Right now I have to keep selecting what I want to put there, which is pretty tedious when one is adding a lot of new blocks. The canvas app I use now is called Deepnotes. There I just double click, and the basic canvas block gets added automatically. Personally I don't even need any other type of block, but this might be different for other people. Anyway, I saved the app, looking forward to see how it will develop.
