Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.
