Best for	Engineering teams offloading tickets. Ops/platform work.	Replacing Google for any question where you want a cited answer in seconds.	Frontend devs, PMs prototyping UIs, anyone on Next.js.	Podcasters, course creators, anyone editing talking-head content.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	Edit audio/video by deleting text Overdub (voice clone) for fixes Strong collaboration + remote recording
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	Not a general chatbot Answers can be shallow on complex topics	Best for shadcn stack Iterating can be fiddly	Not a traditional NLE — some workflows awkward Overdub ethics require care
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier. If you're on Vercel/shadcn, this is cheating.	S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
