Doesn't Google already have a notes app (Keep) and a document app? How about improving the existing products rather than launching something new. This is clearly something that you can add to Keep and remove later if it is a failure.
Google product managers get bonuses for launching new product, not for improving existing products. It really warps their product portfolio and undermines long term support for products. This is why they have launched a series of chat apps and them let each one languish.
