General chatbots are great for things they have general data about. "What was that movie where..." type things. They don't help with individualized information, unless you feed the same type of information as Recall type solutions gather anyways. Perhaps you don't have much individualized information, or perhaps you just remember it all very aptly - it shouldn't be hard to imagine differently though.

My main usage problem with Recall type solutions is less with lack of something to promise and more with lack of ability to deliver. Especially for local-only solutions. The concept can be great as can be, but it needs to be damn near foolproof to beat out how much we already remember.
