| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | If you're doing neuro-AI research, this is the plumbing you've been manually building for years — finally done right by the team that actually runs these experiments at scale. Extremely narrow use case, but within that lane it looks genuinely best-in-class. (Verdict pending Phi's full review.) | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier in its category. The first AI music tool I'd actually listen to. |
