Kai's verdictA-tier. Best for cinematic image-to-video. Pair with Runway for coverage.A-tier. Niche but beloved. If you've outgrown Notion, try this.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.
