| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform. |
