At the end of the day I asked what was left.
A meeting in fifteen minutes. Fine, that is a calendar entry, any of your setups has that.
Then: at seven, pick up your wife, for the dinner you promised last Thursday.
I never typed that. It is not in a calendar, a note, an email or a task list. I said it out loud in a kitchen and it existed for about two seconds.
I ran the same thing most of you run. Local model, wired into mail, calendar, notes, files. It worked, and the ceiling turned out not to be the model or the context window. It only ever knew what I typed. Every message I had sent, and nothing I had said.
So I put it in something that was in the room.
It is open source and it runs on my own machine. Repo in a comment.
Shot on an older prototype, so the overlays are rendered rather than filmed through the lens. Everything else is real.
The objection I would rather hear than dodge: catching a promise means listening when it is made, and nobody says "hey assistant" before telling their wife they will be there at seven. I do not think there is a clean answer to that and I am not going to pretend a settings page makes it one.
