Automatically create a knowledge base from your notes, Google Docs and Gmail - is that useful?

Hi everyone,

I'm working on a note taking tool that's able to link across your notes, Google docs and Gmail and suggest you snippets of relevant information while writing.

I decided to work on this because I had the problem of linking snippets of user interviews stored in Google Docs, chats and email to features I was working on in the past. I tried different note taking tools but they can't really do that and I always had to copy and paste from the source.

The core 3 benefits are:

→ Linking between documents happens automatically. As soon as you type a name or a company for example, the tool will suggest relevant information across your notes and documents without tagging.
→ You can drag & drop paragraphs of text from a note, Google Doc or email to create a live reference.
→ Navigating between different external documents with a bird's eye view, so you don't have to switch tabs and windows.

Here's a walk-through of what I'm working on: https://imgur.com/idhH5y3

Would that be something useful?

How would you validate this idea?
