Category	Agents	Design	Writing	Video
Pricing	$500/mo	Included with Figma plans	Free + $12/mo	Free + $24-$65/mo
Best for	Engineering teams offloading tickets. Ops/platform work.	Designers already on Figma.	Essays, long-form drafts, thinking on the page.	Course creators, multilingual marketers, anyone scaling video content.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	First drafts with Make Designs Rename/rearrange layers automatically Natural language asset search	Clean writing UX — distraction-free +++ prompt triggers AI help Collaboration + AI feedback together	Clone your face + voice in 2 minutes Instant translation into 40+ languages with lip sync Avatars look less uncanny than competitors
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	Features vary by plan + region Still rolling out	Less feature-rich than Google Docs AI ceiling below dedicated tools	Pricey for serious volume Long shots still feel off Ethics — easy to misuse
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	A-tier. No reason not to use it if you're on Figma. Not worth switching for.	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
