| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | S-tier inside Photoshop (Generative Fill). B-tier standalone. | A-tier. Bet on this one — the Sparkpage format is genuinely new. |
