What People Say
Gave it my messy notes from three meetings. Got a plan I could actually send.
It caught a mistake in my spreadsheet I'd have shipped to a client.
I paste the whole codebase now. It remembers what we discussed forty messages ago.
First AI that pushed back on me instead of agreeing with everything.
Turned a 90-page policy doc into the four rules that apply to me.
My drafts sound like me now. It edits, it doesn't rewrite.
Asked it to plan a week of dinners around what was in my fridge. Nailed it.
I use it for work and my mother uses it for her doctor letters.
