| Kai's verdict | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for solo + free. The best free option, hands down. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. |
