Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for text-in-image. Use this for posters, Midjourney for art.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.
