Kai's verdictS-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for open-source model APIs. The default in this space.
