Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Still early. Manus is more flexible for less money.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
