Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
