| Kai's verdict | If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.) | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. | A-tier for sales teams. B-tier for solo users. |
