Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
