Strengths	Very strong motion + physics Often beats Runway on realism Great price	Most mature video workflow Character consistency via Act-One Gen-4 quality is production-grade	Great enterprise story Works in your existing IDE Chat + autocomplete	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous
Weaknesses	UX is rough for English speakers Queue times	Expensive at scale Still needs post-editing	Less agentic than Cursor/Claude Code Model quality varies	Writing quality trails Claude Over-refusals on edge content UI is cluttered
Kai's verdict	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	S-tier. Market leader with reason. Start here for serious video.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
