Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for model-shopping. I use this for every prototype before committing.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
