Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier. If you're on Vercel/shadcn, this is cheating.
