Kai's verdictS-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
