Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
