Weaknesses

Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for open-source model APIs. The default in this space.
