Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier in its niche. The only one that actually gets emotion right.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
