Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for text-in-image. Use this for posters, Midjourney for art.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.
