Kai's verdict	A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
