Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
