No surprises.

An assistant that only answers questions is basically a search box. The useful ones do things, like filing notes, linking them, merging them and tidying up. Anything with that much access to your notes has to be something you can trust.

That trust comes from being able to check. You should be able to make it ask before it changes anything. It should show every change as a before and after, and if an edit looks like it has dropped some of your words, it should tell you straight away. Any clean-up should be undoable in one step.

It’s what you’d expect from a colleague with the keys to your files: tell me what you did, and let me undo it.
