Kai's verdictB-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.A-tier if you already pay Gemini. B-tier standalone.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
