| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for academic research. Nothing else comes close for systematic reviews. | A-tier. Great price/performance. Go here if ElevenLabs is too expensive. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. |
